+Bug 1410214: Part 2 - Add a stub Hunspell FileMgr that allows it to read URLs. r=masayuki
+
+This will allow us to store dictionaries in packed extension XPIs and/or
+omni.ja, which should give us a significant startup performance win.

+# About Hunspell
+
+Hunspell is a free spell checker and morphological analyzer library
+and command-line tool, licensed under LGPL/GPL/MPL tri-license.
+
+Hunspell is used by LibreOffice office suite, free browsers, like
+Mozilla Firefox and Google Chrome, and other tools and OSes, like
+Linux distributions and macOS. It is also a command-line tool for
+Linux, Unix-like and other OSes.
+
+It is designed for quick and high quality spell checking and
+correcting for languages with word-level writing system,
+including languages with rich morphology, complex word compounding
+and character encoding.
+
+Hunspell interfaces: Ispell-like terminal interface using Curses
+library, Ispell pipe interface, C++/C APIs and shared library, also
+with existing language bindings for other programming languages.
+
+Hunspell's code base comes from OpenOffice.org's MySpell library,
+developed by Kevin Hendricks (originally a C++ reimplementation of
+spell checking and affixation of Geoff Kuenning's International
+Ispell from scratch, later extended with eg. n-gram suggestions),
+see http://lingucomponent.openoffice.org/MySpell-3.zip, and
+its README, CONTRIBUTORS and license.readme (here: license.myspell) files.
+
+Main features of Hunspell library, developed by László Németh:

+  - Unicode support
+  - Highly customizable suggestions: word-part replacement tables and
+    stem-level phonetic and other alternative transcriptions to recognize
+    and fix all typical misspellings, don't suggest offensive words etc.
+  - Complex morphology: dictionary and affix homonyms; twofold affix
+    stripping to handle inflectional and derivational morpheme groups for
+    agglutinative languages, like Azeri, Basque, Estonian, Finnish, Hungarian,
+    Turkish; 64 thousand affix classes with arbitrary number of affixes;
+    conditional affixes, circumfixes, fogemorphemes, zero morphemes,
+    virtual dictionary stems, forbidden words to avoid overgeneration etc.
+  - Handling complex compounds (for example, for Finno-Ugric, German and
+    Indo-Aryan languages): recognizing compounds made of arbitrary
+    number of words, handle affixation within compounds etc.
+  - Custom dictionaries with affixation
+  - Stemming
+  - Morphological analysis (in custom item and arrangement style)
+  - Morphological generation
+  - SPELLML XML API over plain spell() API function for easier integration
+    of stemming, morpological generation and custom dictionaries with affixation
+  - Language specific algorithms, like special casing of Azeri or Turkish
+    dotted i and German sharp s, and special compound rules of Hungarian.
+
+Main features of Hunspell command line tool, developed by László Németh:
+
+  - Reimplementation of quick interactive interface of Geoff Kuenning's Ispell
+  - Parsing formats: text, OpenDocument, TeX/LaTeX, HTML/SGML/XML, nroff/troff
+  - Custom dictionaries with optional affixation, specified by a model word
+  - Multiple dictionary usage (for example hunspell -d en_US,de_DE,de_medical)
+  - Various filtering options (bad or good words/lines)
+  - Morphological analysis (option -m)
+  - Stemming (option -s)

+# Dependencies
+
+Build only dependencies:
+
+    g++ make autoconf automake autopoint libtool
+
+Runtime dependencies:
+
+|               | Mandatory        | Optional         |
+|---------------|------------------|------------------|
+|libhunspell    |                  |                  |
+|hunspell tool  | libiconv gettext | ncurses readline |
+
+# Compiling on GNU/Linux and Unixes
+
+We first need to download the dependencies. On Linux, `gettext` and
+`libiconv` are part of the standard library. On other Unixes we
+need to manually install them.
+
+For Ubuntu:
+
+    sudo apt install autoconf automake autopoint libtool
+
+Then run the following commands:
+
+    autoreconf -vfi
+    ./configure
+    make
+    sudo make install
+    sudo ldconfig
+
+For dictionary development, use the `--with-warnings` option of
+configure.
+
+For interactive user interface of Hunspell executable, use the
+`--with-ui option`.
+
+Optional developer packages:
+
+  - ncurses (need for --with-ui), eg. libncursesw5 for UTF-8
+  - readline (for fancy input line editing, configure parameter:
+    --with-readline)
+
+In Ubuntu, the packages are:
+
+    libncurses5-dev libreadline-dev
+
+# Compiling on OSX and macOS
+
+On macOS for compiler always use `clang` and not `g++` because Homebrew
+dependencies are build with that.
+
+    brew install autoconf automake libtool gettext
+    brew link gettext --force
+
+Then run autoreconf, configure, make. See above.
+
+# Compiling on Windows
+
+## Compiling with Mingw64 and MSYS2
+
+Download Msys2, update everything and install the following
+    packages:
+
+    pacman -S base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-libtool
+
+Open Mingw-w64 Win64 prompt and compile the same way as on Linux, see
+above.
+
+## Compiling in Cygwin environment
+
+Download and install Cygwin environment for Windows with the following
+extra packages:
+
+  - make
+  - automake
+  - autoconf
+  - libtool
+  - gcc-g++ development package
+  - ncurses, readline (for user interface)
+  - iconv (character conversion)
+
+Then compile the same way as on Linux. Cygwin builds depend on
+Cygwin1.dll.
+
+# Debugging
+
+It is recommended to install a debug build of the standard library:
+
+    libstdc++6-6-dbg
+
+For debugging we need to create a debug build and then we need to start
+`gdb`.
+
+    ./configure CXXFLAGS='-g -O0 -Wall -Wextra'
+    make
+    ./libtool --mode=execute gdb src/tools/hunspell
+
+You can also pass the `CXXFLAGS` directly to `make` without calling
+`./configure`, but we don't recommend this way during long development
+sessions.
+
+If you like to develop and debug with an IDE, see documentation at
+https://github.com/hunspell/hunspell/wiki/IDE-Setup
+
+# Testing
+
+Testing Hunspell (see tests in tests/ subdirectory):
+
+    make check
+
+or with Valgrind debugger:
+
+    make check
+    VALGRIND=[Valgrind_tool] make check
+
+For example:
+
+    make check
+    VALGRIND=memcheck make check
+
+# Documentation
+
+features and dictionary format:
+
+    man 5 hunspell
+    man hunspell
+    hunspell -h
+
+http://hunspell.github.io/
+
+# Usage
+
+After compiling and installing (see INSTALL) you can run the Hunspell
+spell checker (compiled with user interface) with a Hunspell or Myspell
+dictionary:
+
+    hunspell -d en_US text.txt
+
+or without interface:
+
+    hunspell
+    hunspell -d en_GB -l <text.txt
+
+Dictionaries consist of an affix (.aff) and dictionary (.dic) file, for
+example, download American English dictionary files of LibreOffice
+(older version, but with stemming and morphological generation) with
+
+    wget -O en_US.aff  https://cgit.freedesktop.org/libreoffice/dictionaries/plain/en/en_US.aff?id=a4473e06b56bfe35187e302754f6baaa8d75e54f
+    wget -O en_US.dic https://cgit.freedesktop.org/libreoffice/dictionaries/plain/en/en_US.dic?id=a4473e06b56bfe35187e302754f6baaa8d75e54f
+
+and with command line input and output, it's possible to check its work quickly,
+for example with the input words "example", "examples", "teached" and
+"verybaaaaaaaaaaaaaaaaaaaaaad":
+
+    $ hunspell -d en_US
+    Hunspell 1.7.0
+    example
+    *
+
+    examples
+    + example
+
+    teached
+    & teached 9 0: taught, teased, reached, teaches, teacher, leached, beached
+
+    verybaaaaaaaaaaaaaaaaaaaaaad
+    # verybaaaaaaaaaaaaaaaaaaaaaad 0
+
+Where in the output, `*` and `+` mean correct (accepted) words (`*` = dictionary stem,
+`+` = affixed forms of the following dictionary stem), and
+`&` and `#` mean bad (rejected) words (`&` = with suggestions, `#` = without suggestions)
+(see man hunspell).
+
+Example for stemming:
+
+    $ hunspell -d en_US -s
+    mice
+    mice mouse
+
+Example for morphological analysis (very limited with this English dictionary):
+
+    $ hunspell -d en_US -m
+    mice
+    mice  st:mouse ts:Ns
+
+    cats
+    cats  st:cat ts:0 is:Ns
+    cats  st:cat ts:0 is:Vs
+
+# Other executables
+
+The src/tools directory contains the following executables after compiling.
+
+  - The main executable:
+      - hunspell: main program for spell checking and others (see
+        manual)
+  - Example tools:
+      - analyze: example of spell checking, stemming and morphological
+        analysis
+      - chmorph: example of automatic morphological generation and
+        conversion
+      - example: example of spell checking and suggestion
+  - Tools for dictionary development:
+      - affixcompress: dictionary generation from large (millions of
+        words) vocabularies
+      - makealias: alias compression (Hunspell only, not back compatible
+        with MySpell)
+      - wordforms: word generation (Hunspell version of unmunch)
+      - hunzip: decompressor of hzip format
+      - hzip: compressor of hzip format
+      - munch (DEPRECATED, use affixcompress): dictionary generation
+        from vocabularies (it needs an affix file, too).
+      - unmunch (DEPRECATED, use wordforms): list all recognized words
+        of a MySpell dictionary
+
+Example for morphological generation:
+
+    $ ~/hunspell/src/tools/analyze en_US.aff en_US.dic /dev/stdin
+    cat mice
+    generate(cat, mice) = cats
+    mouse cats
+    generate(mouse, cats) = mice
+    generate(mouse, cats) = mouses

+
+Appendix:  Understanding Affix Code
+
+
+An affix is either a  prefix or a suffix attached to root words to make 
+other words.
+
+Basically a Prefix or a Suffix is set of AffEntry objects
+which store information about the prefix or suffix along 
+with supporting routines to check if a word has a particular 
+prefix or suffix or a combination.
+
+The structure affentry is defined as follows:
+
+struct affentry
+{
+   unsigned short aflag;    // ID used to represent the affix
+   std::string strip;       // string to strip before adding affix
+   std::string appnd;       // the affix string to add
+   char numconds;           // the number of conditions that must be met
+   char opts;               // flag: aeXPRODUCT- combine both prefix and suffix 
+   char   conds[SETSIZE];   // array which encodes the conditions to be met
+};
+
+
+Here is a suffix borrowed from the en_US.aff file.  This file 
+is whitespace delimited.
+
+SFX D Y 4 
+SFX D   0     e          d
+SFX D   y     ied        [^aeiou]y
+SFX D   0     ed         [^ey]
+SFX D   0     ed         [aeiou]y
+
+This information can be interpreted as follows:
+
+In the first line has 4 fields
+
+Field
+-----
+1     SFX - indicates this is a suffix
+2     D   - is the name of the character flag which represents this suffix
+3     Y   - indicates it can be combined with prefixes (cross product)
+4     4   - indicates that sequence of 4 affentry structures are needed to
+               properly store the affix information
+
+The remaining lines describe the unique information for the 4 SfxEntry 
+objects that make up this affix.  Each line can be interpreted
+as follows: (note fields 1 and 2 are as a check against line 1 info)
+
+Field
+-----
+1     SFX         - indicates this is a suffix
+2     D           - is the name of the character flag for this affix
+3     y           - the string of chars to strip off before adding affix
+                         (a 0 here indicates the NULL string)
+4     ied         - the string of affix characters to add
+5     [^aeiou]y   - the conditions which must be met before the affix
+                    can be applied
+
+Field 5 is interesting.  Since this is a suffix, field 5 tells us that
+there are 2 conditions that must be met.  The first condition is that 
+the next to the last character in the word must *NOT* be any of the 
+following "a", "e", "i", "o" or "u".  The second condition is that
+the last character of the word must end in "y".
+
+So how can we encode this information concisely and be able to 
+test for both conditions in a fast manner?  The answer is found
+but studying the wonderful ispell code of Geoff Kuenning, et.al. 
+(now available under a normal BSD license).
+
+If we set up a conds array of 256 bytes indexed (0 to 255) and access it
+using a character (cast to an unsigned char) of a string, we have 8 bits
+of information we can store about that character.  Specifically we
+could use each bit to say if that character is allowed in any of the 
+last (or first for prefixes) 8 characters of the word.
+
+Basically, each character at one end of the word (up to the number 
+of conditions) is used to index into the conds array and the resulting 
+value found there says whether the that character is valid for a 
+specific character position in the word.  
+
+For prefixes, it does this by setting bit 0 if that char is valid 
+in the first position, bit 1 if valid in the second position, and so on. 
+
+If a bit is not set, then that char is not valid for that postion in the
+word.
+
+If working with suffixes bit 0 is used for the character closest 
+to the front, bit 1 for the next character towards the end, ..., 
+with bit numconds-1 representing the last char at the end of the string. 
+
+Note: since entries in the conds[] are 8 bits, only 8 conditions 
+(read that only 8 character positions) can be examined at one
+end of a word (the beginning for prefixes and the end for suffixes.
+
+So to make this clearer, lets encode the conds array values for the 
+first two affentries for the suffix D described earlier.
+
+
+  For the first affentry:    
+     numconds = 1             (only examine the last character)
+
+     conds['e'] =  (1 << 0)   (the word must end in an E)
+     all others are all 0
+
+  For the second affentry:
+     numconds = 2             (only examine the last two characters)     
+
+     conds[X] = conds[X] | (1 << 0)     (aeiou are not allowed)
+         where X is all characters *but* a, e, i, o, or u
+         
+
+     conds['y'] = (1 << 1)     (the last char must be a y)
+     all other bits for all other entries in the conds array are zero

+#   Changelog:
+#
+#   2000-01-05  Björn Jacke <bjoern.jacke@gmx.de>
+#               - first version with translation rules derived from
+#                 metaphone.cc distributed with aspell 0.28.3
+#               - "TH" is now representated as "@" because "0" is a
+#                 meta character
+#               - removed TH(!vowel) --> T; always use TH --> # instead
+#               - dropped "^AE" -> "E" (redundant)
+#               - "ing" is transformed to "N", not "NK"
+#               - "SCH(EO)" transforms to "SK" now
+#               - added R --> SILENT if (after a vowel) and no (vowel or
+#                 "y" follows) like in "Marcy" or "abort"
+#               - H is SILENT in RH at beginning of words
+#               - H is SILENT if vowel leads and "Y" follows
+#               - some ".OUGH.."  --> ...F exceptions added
+#               - "^V" transforms to "W"
+#   2000-01-07  Kevin Atkinson <kevinatk@home.com>
+#               Converted from header to data file.
+#
+#   2007-08-23  László Németh <nemeth AT OOo>
+#               Add PHONE header and PHONE keywords
