Subject: [PATCH] fix #131649 - extended charclass can trigger assert
The extended charclass parser makes some assumptions during the
first pass which are only true on well structured input, and it
does not properly catch various errors. later on the code assumes
that things the first pass will let through are valid, when in
fact they should trigger errors.

Subject: [PATCH] Perl_my_setenv(); handle integer wrap
RT #133204
Wean this function off int/I32 and onto UV/Size_t.
Also, replace all malloc-ish calls with a wrapper that does
overflow checks,
In particular, it was doing (nlen + vlen + 2) which could wrap when
the combined length of the environment variable name and value
exceeded around 0x7fffffff.
The wrapper check function is probably overkill, but belt and braces...
NB this function has several variant parts, #ifdef'ed by platform
type; I have blindly changed the parts that aren't compiled under linux.
