+ *
+ * In the case of the UTF-8 encoding, all multibyte characters all fall outside
+ * of the C/POSIX range of characters, so these functions are generally safe
+ * to use on UTF-8 strings. The programmer must be aware that each octet may
+ * not represent a distinct printable character in such encodings.

+ * RFC4648 and RFC7515 compliant BASE64, BASE64URL, BASE32, BASE32HEX
+ * and BASE16 encode/decode functions.
+ *
+ * The following encodings are supported:
+ *
+ * - Base 64 Encoding
+ *
+ * o Use flag APR_ENCODE_NONE
+ * o https://tools.ietf.org/html/rfc4648#section-4
+ *
+ * - Base 64 Encoding with URL and Filename Safe Alphabet
+ *
+ * o Use flag APR_ENCODE_URL
+ * o https://tools.ietf.org/html/rfc4648#section-5
+ *
+ * - Base 64 URL Encoding without Padding
+ *
+ * o Use flag APR_ENCODE_BASE64URL
+ * o https://tools.ietf.org/html/rfc7515#appendix-C
+ *
+ * - Base 32 Encoding
+ *
+ * o Use flag APR_ENCODE_NONE
+ * o https://tools.ietf.org/html/rfc4648#section-6
+ *
+ * - Base 32 Encoding with Extended Hex Alphabet
+ *
+ * o Use flag APR_ENCODE_BASE32HEX
+ * o https://tools.ietf.org/html/rfc4648#section-7
+ *
+ * - Base 16 Encoding
+ *
+ * o Use flags APR_ENCODE_NONE/APR_ENCODE_COLON
+ * o https://tools.ietf.org/html/rfc4648#section-8
+ *
+ * If a non valid character of any kind including whitespace is passed to any
+ * of the decoder functions, APR_BADCH will be returned. In this case decoding
+ * will still take place, but the results can not be trusted.
+ *
+ * If APR_ENCODE_RELAXED is passed to the decoder functions, decoding will be
+ * attempted up until the first non valid character. If this results in an
+ * invalid state in the decoder, such as but not limited to an odd number of
+ * base16 characters, APR_BADCH will still be returned.
+ *
+ * If APR_ENCODE_RELAXED is not passed to a decoder function, the decoding will
+ * be done in constant time regardless of whether the result returns APR_SUCCESS
+ * or APR_BADCH.
+ *
+ * If the dest parameter is NULL, the maximum theoretical buffer size is
+ * returned in the len field, including space for a terminating zero character
+ * if the destination is a string. This value can be used to allocate buffers
+ * of a suitable safe size.
+ *
+ * If the dest parameter is provided, the encoding or decoding will take place,
+ * and the actual number of characters written is returned in the len field,
+ * ignoring any terminating zero.
+ *
+ * Plain strings are not assumed '\0' terminated unless APR_ENCODE_STRING is
+ * provided.

+ * applications known to be able to decipher them. APR does not
+ * guarantee that it will compress the file into sparse segments

+ *
+ * PATTERN: [ followed by a class description followed by ]<br/>
+ * MATCHES: A single character described by the class description.
+ * (Never matches, if the class description reaches until the
+ * end of the string without a ].) If the first character of
+ * the class description is ^ or !, the sense of the description
+ * is reversed. The rest of the class description is a list of
+ * single characters or pairs of characters separated by -. Any
+ * of those characters can have a backslash in front of them,
+ * which is ignored; this lets you use the characters ] and -
+ * in the character class, as well as ^ and ! at the
+ * beginning. The pattern matches a single character if it
+ * is one of the listed characters or falls into one of the
+ * listed ranges (inclusive, case sensitive). Ranges with
+ * the first character larger than the second are legal but
+ * never match. Edge cases: [] never matches, and [^] and [!]
+ * always match without consuming a character.

+ * @param fmt The format string
+ * @param ap The arguments to use to fill out the format string.
+ *
+ * @remark
+ * <PRE>
+ * The extensions are:
+ *
+ * - %%pA takes a struct in_addr *, and prints it as a.b.c.d
+ * - %%pI takes an apr_sockaddr_t * and prints it as a.b.c.d:port or
+ * \[ipv6-address\]:port
+ * - %%pT takes an apr_os_thread_t * and prints it in decimal
+ * ('0' is printed if !APR_HAS_THREADS)
+ * - %%pt takes an apr_os_thread_t * and prints it in hexadecimal
+ * ('0' is printed if !APR_HAS_THREADS)
+ * - %%pm takes an apr_status_t * and prints the appropriate error
+ * string (from apr_strerror) corresponding to that error code.
+ * - %%pp takes a void * and outputs it in hex
+ * - %%pB takes a apr_uint32_t * as bytes and outputs it's apr_strfsize
+ * - %%pF same as above, but takes a apr_off_t *
+ * - %%pS same as above, but takes a apr_size_t *
+ *
+ * %%pA, %%pI, %%pT, %%pp are available from APR 1.0.0 onwards (and in 0.9.x).
+ * %%pt is only available from APR 1.2.0 onwards.
+ * %%pm, %%pB, %%pF and %%pS are only available from APR 1.3.0 onwards.
+ *
+ * The %%p hacks are to force gcc's printf warning code to skip
+ * over a pointer argument without complaining. This does
+ * mean that the ANSI-style %%p (output a void * in hex format) won't
+ * work as expected at all, but that seems to be a fair trade-off
+ * for the increased robustness of having printf-warnings work.
+ *
+ * Additionally, apr_vformatter allows for arbitrary output methods
+ * using the apr_vformatter_buff and flush_func.
+ *
+ * The apr_vformatter_buff has two elements curpos and endpos.
+ * curpos is where apr_vformatter will write the next byte of output.
+ * It proceeds writing output to curpos, and updating curpos, until
+ * either the end of output is reached, or curpos == endpos (i.e. the
+ * buffer is full).
+ *
+ * If the end of output is reached, apr_vformatter returns the
+ * number of bytes written.
+ *
+ * When the buffer is full, the flush_func is called. The flush_func
+ * can return -1 to indicate that no further output should be attempted,
+ * and apr_vformatter will return immediately with -1. Otherwise
+ * the flush_func should flush the buffer in whatever manner is
+ * appropriate, re apr_pool_t nitialize curpos and endpos, and return 0.
+ *
+ * Note that flush_func is only invoked as a result of attempting to
+ * write another byte at curpos when curpos >= endpos. So for
+ * example, it's possible when the output exactly matches the buffer
+ * space available that curpos == endpos will be true when
+ * apr_vformatter returns.
+ *
+ * apr_vformatter does not call out to any other code, it is entirely
+ * self-contained. This allows the callers to do things which are
+ * otherwise "unsafe". For example, apr_psprintf uses the "scratch"
+ * space at the unallocated end of a block, and doesn't actually
+ * complete the allocation until apr_vformatter returns. apr_psprintf
+ * would be completely broken if apr_vformatter were to call anything
+ * that used this same pool. Similarly http_bprintf() uses the "scratch"
+ * space at the end of its output buffer, and doesn't actually note
+ * that the space is in use until it either has to flush the buffer
+ * or until apr_vformatter returns.

+ *
+ * Instead, we maintain pools, and allocate items (both memory and I/O
+ * handlers) from the pools --- currently there are two, one for
+ * per-transaction info, and one for config info. When a transaction is
+ * over, we can delete everything in the per-transaction apr_pool_t without
+ * fear, and without thinking too hard about it either.
+ *
+ * Note that most operations on pools are not thread-safe: a single pool
+ * should only be accessed by a single thread at any given time. The one
+ * exception to this rule is creating a subpool of a given pool: one or more
+ * threads can safely create subpools at the same time that another thread
+ * accesses the parent pool.

+ *
+ * pools have nested lifetimes -- sub_pools are destroyed when the
+ * parent pool is cleared. We allow certain liberties with operations
+ * on things such as tables (and on other structures in a more general
+ * sense) where we allow the caller to insert values into a table which
+ * were not allocated from the table's pool. The table's data will
+ * remain valid as long as all the pools from which its values are
+ * allocated remain valid.
+ *
+ * For example, if B is a sub pool of A, and you build a table T in
+ * pool B, then it's safe to insert data allocated in A or B into T
+ * (because B lives at most as long as A does, and T is destroyed when
+ * B is cleared/destroyed). On the other hand, if S is a table in
+ * pool A, it is safe to insert data allocated in A into S, but it
+ * is *not safe* to insert data allocated from B into S... because
+ * B can be cleared/destroyed before A is (which would leave dangling
+ * pointers in T's data structures).
+ *
+ * In general we say that it is safe to insert data into a table T
+ * if the data is allocated in any ancestor of T's pool. This is the
+ * basis on which the APR_POOL_DEBUG code works -- it tests these ancestor
+ * relationships for all data inserted into tables. APR_POOL_DEBUG also
+ * provides tools (apr_pool_find, and apr_pool_is_ancestor) for other
+ * folks to implement similar restrictions for their own data
+ * structures.
+ *
+ * However, sometimes this ancestor requirement is inconvenient --
+ * sometimes it's necessary to create a sub pool where the sub pool is
+ * guaranteed to have the same lifetime as the parent pool. This is a
+ * guarantee implemented by the *caller*, not by the pool code. That
+ * is, the caller guarantees they won't destroy the sub pool
+ * individually prior to destroying the parent pool.
+ *
+ * In this case the caller must call apr_pool_join() to indicate this
+ * guarantee to the APR_POOL_DEBUG code.

+ * APR_RING_HEAD declaration.
+ *
+ * @warning For strict C standards compliance you should put the APR_RING_ENTRY
+ * first in the element struct unless the head is always part of a larger
+ * object with enough earlier fields to accommodate the offsetof() used
+ * to compute the ring sentinel below. You can usually ignore this caveat.

+/**
+ * The Ring Sentinel
+ *
+ * This is the magic pointer value that occurs before the first and
+ * after the last elements in the ring, computed from the address of
+ * the ring's head. The head itself isn't an element, but in order to
+ * get rid of all the special cases when dealing with the ends of the
+ * ring, we play typecasting games to make it look like one.
+ *
+ * Here is a diagram to illustrate the arrangements of the next and
+ * prev pointers of each element in a single ring. Note that they point
+ * to the start of each element, not to the APR_RING_ENTRY structure.
+ *
+ * <pre>
+ * +->+------+<-+ +->+------+<-+ +->+------+<-+
+ * | |struct| | | |struct| | | |struct| |
+ * / | elem | \/ | elem | \/ | elem | \
+ * ... | | /\ | | /\ | | ...
+ * +------+ | | +------+ | | +------+
+ * ...--|prev | | +--|ring | | +--|prev |
+ * | next|--+ | entry|--+ | next|--...
+ * +------+ +------+ +------+
+ * | etc. | | etc. | | etc. |
+ * : : : : : :
+ * </pre>
+ *
+ * The APR_RING_HEAD is nothing but a bare APR_RING_ENTRY. The prev
+ * and next pointers in the first and last elements don't actually
+ * point to the head, they point to a phantom place called the
+ * sentinel. Its value is such that last->next->next == first because
+ * the offset from the sentinel to the head's next pointer is the same
+ * as the offset from the start of an element to its next pointer.
+ * This also works in the opposite direction.
+ *
+ * <pre>
+ * last first
+ * +->+------+<-+ +->sentinel<-+ +->+------+<-+
+ * | |struct| | | | | |struct| |
+ * / | elem | \/ \/ | elem | \

+ * | next|--+ | head|--+ | next|--...
+ * +------+ +------+ +------+
+ * | etc. | | etc. |
+ * : : : :
+ * </pre>
+ *
+ * Note that the offset mentioned above is different for each kind of
+ * ring that the element may be on, and each kind of ring has a unique
+ * name for its APR_RING_ENTRY in each element, and has its own type
+ * for its APR_RING_HEAD.
+ *
+ * Note also that if the offset is non-zero (which is required if an
+ * element has more than one APR_RING_ENTRY), the unreality of the
+ * sentinel may have bad implications on very perverse implementations
+ * of C -- see the warning in APR_RING_ENTRY.
