/*
* Idioms used in this code:
*
*
* Consuming the next input character
*
* To consume the next input character, the code does this: if (++pos ==
* endPos) { break stateloop; } c = checkChar(buf, pos);
*
*
* Staying in a state
*
* When there's a state that the tokenizer may stay in over multiple
* input characters, the state has a wrapper |for(;;)| loop and staying
* in the state continues the loop.
*
*
* Switching to another state
*
* To switch to another state, the code sets the state variable to the
* magic number of the new state. Then it either continues stateloop or
* breaks out of the state's own wrapper loop if the target state is
* right after the current state in source order. (This is a partial
* workaround for Java's lack of goto.)
*
*
* Reconsume support
*
* The spec sometimes says that an input character is reconsumed in
* another state. If a state can ever be entered so that an input
* character can be reconsumed in it, the state's code starts with an
* |if (reconsume)| that sets reconsume to false and skips over the
* normal code for consuming a new character.
*
* To reconsume the current character in another state, the code sets
* |reconsume| to true and then switches to the other state.
*
*
* Emitting character tokens
*
* This method emits character tokens lazily. Whenever a new range of
* character tokens starts, the field cstart must be set to the start
* index of the range. The flushChars() method must be called at the end
* of a range to flush it.
*
*
* U+0000 handling
*
* The various states have to handle the replacement of U+0000 with
* U+FFFD. However, if U+0000 would be reconsumed in another state, the
* replacement doesn't need to happen, because it's handled by the
* reconsuming state.
*
*
* LF handling
*
* Every state needs to increment the line number upon LF unless the LF
* gets reconsumed by another state which increments the line number.
*
*
* CR handling
*
* Every state needs to handle CR unless the CR gets reconsumed and is
* handled by the reconsuming state. The CR needs to be handled as if it
* were and LF, the lastCR field must be set to true and then this
* method must return. The IO driver will then swallow the next
* character if it is an LF to coalesce CRLF.

* to omit parts of it: The second dimension of the
* table is null when no character reference starts with
* the character corresponding to that row.
*
* The int value HILO_ACCEL (by these indeces) is zero
* if there exists no character reference starting with
* that two-letter prefix. Otherwise, the value is an
* int that packs two shorts so that the higher short is
* the index of the highest character reference name
* with that prefix in NAMES and the lower short
* corresponds to the index of the lowest character
* reference name with that prefix. (It happens that the
* first two character reference names share their
* prefix so the packed int cannot be 0 by packing the
* two shorts.)
*
* NAMES is an array of byte arrays where each byte
* array encodes the name of a character references as
* ASCII. The names omit the first two letters of the
* name. (Since storing the first two letters would be
* redundant with the data contained in HILO_ACCEL.) The
* entries are lexically sorted.
*
* For a given index in NAMES, the same index in VALUES
