* Function fnmatch() as specified in POSIX 1003.2-1992, section B.6.
* Compares a filename or pathname to a pattern.
/* Authored by William A. Rowe Jr. <wrowe; apache.org, vmware.com>, April 2011
*
* Derived from The Open Group Base Specifications Issue 7, IEEE Std 1003.1-2008
* as described in;
* http://pubs.opengroup.org/onlinepubs/9699919799/functions/fnmatch.html
*
* Filename pattern matches defined in section 2.13, "Pattern Matching Notation"
* from chapter 2. "Shell Command Language"
* http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13
* where; 1. A bracket expression starting with an unquoted <circumflex> '^'
* character CONTINUES to specify a non-matching list; 2. an explicit <period> '.'
* in a bracket expression matching list, e.g. "[.abc]" does NOT match a leading
* <period> in a filename; 3. a <left-square-bracket> '[' which does not introduce
* a valid bracket expression is treated as an ordinary character; 4. a differing
* number of consecutive slashes within pattern and string will NOT match;
* 5. a trailing '\' in FNM_ESCAPE mode is treated as an ordinary '\' character.
*
* Bracket expansion defined in section 9.3.5, "RE Bracket Expression",
* from chapter 9, "Regular Expressions"
* http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_03_05
* with no support for collating symbols, equivalence class expressions or
* character class expressions. A partial range expression with a leading
* hyphen following a valid range expression will match only the ordinary
* <hyphen> and the ending character (e.g. "[a-m-z]" will match characters
* 'a' through 'm', a <hyphen> '-', or a 'z').
*
* Supports BSD extensions FNM_LEADING_DIR to match pattern to the end of one
* path segment of string, and FNM_CASEFOLD to ignore alpha case.
*
* NOTE: Only POSIX/C single byte locales are correctly supported at this time.
* Notably, non-POSIX locales with FNM_CASEFOLD produce undefined results,
* particularly in ranges of mixed case (e.g. "[A-z]") or spanning alpha and
* nonalpha characters within a range.
*
* XXX comments below indicate porting required for multi-byte character sets
* and non-POSIX locale collation orders; requires mbr* APIs to track shift
* state of pattern and string (rewinding pattern and string repeatedly).
*
* Certain parts of the code assume 0x00-0x3F are unique with any MBCS (e.g.
* UTF-8, SHIFT-JIS, etc). Any implementation allowing '\' as an alternate
* path delimiter must be aware that 0x5C is NOT unique within SHIFT-JIS.
