Problem: The "regex" library written by Henry Spencer
does not support tricky character sets like UCS2.
Fix: convert tricky character sets to UTF8 before calling
regex functions.

sql/item_cmpfunc.cc:
- Adding new method Item_func_regex::regcomp()
to share more code between fix_fields() and val_int()
- Adding conversion from ASCII-incompatible charsets like UCS2
to UTF8, because the "regexp" does not support these charsets
- Additional optimization: calculate flags for regcomp only
once in fix_fields, instead of every regcomp()
sql/item_cmpfunc.h:
Adding prototypes for new members and methods
mysql-test/include/ctype_regex.inc:
New BitKeeper file ``mysql-test/include/ctype_regex.inc''
Moving common regular expression tests into a separate
file and uncluding it into func_regexp and into many ctype_xxx tests.
