* create new unicode props as defined in POSIX spec (optionally use them in ↵Yves Orton2008-11-071-12/+34
| | | | | | | | | | | | | | | | | | | | the regex engine) Perlbug #60156 and #49302 (and probably others) resolve down to the problem that the definition of \s and \w and \d and the POSIX charclasses are different for unicode strings and for non-unicode strings. This broke the character class logic in the regex engine. The easiest fix to make the character class logic sane again is to define new properties which do match. This change creates new property classes that can be used instead of the traditional ones (it does not change the previously defined ones). If the define in regcomp.h: #define PERL_LEGACY_UNICODE_CHARCLASS_MAPPINGS 1 is changed to 0, then the new mappings will be used. This will fix a bunch of bugs that are reported as TODO items in the new reg_posixcc.t test file. p4raw-id: //depot/perl@34769

We've already done this at least twice. (Yes, some of the assertions are after code that would already have SEGVd because it already deferences a pointer, but they are put in to make it easier to automate checking that each and every case is covered.)
