  hundreds of events at once using DROP DATABASE.

A prerequisite for several fulltext and XML bugs.
MY_CHARSET_HANDLER now has a new function "ctype"
to detect a type of the next character in a string
(i.e. digit, letter, space, punctuation, control, etc),
which now works correctly for both 8bit and multibyte charsets.
Previously only 8bit charsets worked correctly,
while any multibyte character was considered as letter
in multibyte charsets.
Many files:
  Adding new function
Makefile.am:
  Adding build rules for uctypedump,
  a dump tool to create my_uctype.h
  using Unicode Character Database file.
m_ctype.h:
  Adding declaration of my_uni_ctype,
  ctype data for Unicode.
  Adding new member into MY_CHARSET_HANDLER
Makefile.am:
  Adding my_uctype.h into noinst_HEADERS
my_uctype.h, uctypedump.c:
  new files:
  ctype data for unicode,
  and the tool to generate it from 
  a Unicode Character Database file.
