Regex library is switched to use new ctype tools

to allow usage of many character sets at a time.


include/m_ctype.h:
  Added condition to simplify migrating from old ctype
  Added new style toupper, tolower which accepts charset in first argument
regex/debug.c:
  Added charset argument
regex/debug.ih:
  added charset argument
regex/engine.c:
  added charset argument
regex/engine.ih:
  added charset arguent
regex/main.c:
  added charset argument
regex/regcomp.c:
  added CHARSET_INFO field
regex/regcomp.ih:
  Added charset argument
regex/regex.h:
  Added #include <m_ctype.h> for CHARSET_INFO
  Added charset argument for regcomp()
regex/regex2.h:
  New charset argument for ISWORD()
regex/regexec.c:
  New charset argument
regex/reginit.c:
  Move to new style ctype. 
  However still needs fixes:
    instead of single static cclass variable,
    each charset must have it's own variable.
sql/item_cmpfunc.cc:
  Pass charset field into regcomp()
  This will be fixed tommorow to use String->charset
    instead of default_charset_info
