Laszlo Ersek ffbb5ae3ba MdeModulePkg: RegularExpressionDxe: support free(NULL)
The ISO C standard says about free(),

  If ptr is a null pointer, no action occurs.

This is not true of the FreePool() interface of the MemoryAllocationLib
class:

  Buffer must have been allocated on a previous call to the pool
  allocation services of the Memory Allocation Library. [...] If Buffer
  was not allocated with a pool allocation function in the Memory
  Allocation Library, then ASSERT().

Therefore we must not forward the argument of free() to FreePool() without
checking.

Oniguruma is a regular expressions library.
The characteristics of this library is that different character encoding
for every regular expression object can be specified.

Supported character encodings:

  ASCII, UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE,
  EUC-JP, EUC-TW, EUC-KR, EUC-CN,
  Shift_JIS, Big5, GB18030, KOI8-R, CP1251,
  ISO-8859-1, ISO-8859-2, ISO-8859-3, ISO-8859-4, ISO-8859-5,
  ISO-8859-6, ISO-8859-7, ISO-8859-8, ISO-8859-9, ISO-8859-10,
  ISO-8859-11, ISO-8859-13, ISO-8859-14, ISO-8859-15, ISO-8859-16

Install

 Case 1: Unix and Cygwin platform

   1. ./configure
   2. make
   3. make install

   * uninstall

     make uninstall

   * test (ASCII/EUC-JP)

     make atest

   * configuration check

     onig-config --cflags
     onig-config --libs
     onig-config --prefix
     onig-config --exec-prefix



 Case 2: Win32 platform (VC++)

   1. copy win32\Makefile Makefile
   2. copy win32\config.h config.h
   3. nmake

      onig_s.lib:  static link library
      onig.dll:    dynamic link library

  * test (ASCII/Shift_JIS)
   4. copy win32\testc.c testc.c
   5. nmake ctest



Regular Expressions

  See doc/RE (or doc/RE.ja for Japanese).


Usage

  Include oniguruma.h in your program. (Oniguruma API)
  See doc/API for Oniguruma API.

  If you want to disable UChar type (== unsigned char) definition
  in oniguruma.h, define ONIG_ESCAPE_UCHAR_COLLISION and then 
  include oniguruma.h.

  If you want to disable regex_t type definition in oniguruma.h,
  define ONIG_ESCAPE_REGEX_T_COLLISION and then include oniguruma.h.

  Example of the compiling/linking command line in Unix or Cygwin,
  (prefix == /usr/local case)

    cc sample.c -L/usr/local/lib -lonig


  If you want to use static link library(onig_s.lib) in Win32,
  add option -DONIG_EXTERN=extern to C compiler.

ToDo

  ? case fold flag: Katakana <-> Hiragana.
  ? add ONIG_OPTION_NOTBOS/NOTEOS. (\A, \z, \Z)
 ?? \X (== \PM\pM*)
 ?? implement syntax behavior ONIG_SYN_CONTEXT_INDEP_ANCHORS.
 ?? transmission stopper. (return ONIG_STOP from match_at())

and I'm thankful to Akinori MUSHA.
