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.
