Stop Constant(%s) errors from leaking
This error message uses yyerror, so it doesn’t abort immediately, but

If there are ten accumulated errors, however, yyerror croaks with a

In that circumstance these messages were leaking scalars.
Instead of creating an SV especially to hold the message to pass to
yyerror and then freeing it afterwards, we can instead use Perl_form,
which reuses the same SV every time (PL_mess_sv), eliminating that
leak. In doing so, we can also combine this with another yyerror/
return in the vicinity, avoiding duplicate code.
The sv passed to S_new_constant was also leaking. When there is no
error, it is currently mortalised. When there is an error, it also
needs to be mortalised, in case it is a fatal error. So this commit
changes it to mortalise it unconditionally. This means we have to
SvREFCNT_inc the return value on error.

add PERL_NO_GET_CONTEXT to xs template in h2xs.PL
An XS module not using PERL_NO_GET_CONTEXT is extremely inefficient under
threaded Perls. Prevent PERL_NO_GET_CONTEXT-less modules in the future
by making it a default. Many XS modules are created with h2xs.

Stop renamed packages from making reset() crash
This only affected threaded builds. I think the comments in the added
test explain well enough what was happening.
The solution is to store a stashpad offset in the pmop, instead of the
name of the stash. This is similar to what was done with cop stashes
in
d4d03940c58a.
Not only does this fix the crash, but it also makes compilation faster
and saves memory (no separate malloc for every m?pat?).
I had to move Safefree(PL_stashpad) later on in perl_destruct, because
freeing a pmop causes the PL_stashpad to be accessed, and pmops can be
freed during sv_clean_all. Its previous location was not a problem
for cops, as PL_stashpad[cop->cop_stashoff] is only accessed when
PL_curcop==that_cop and Perl code is running, not when cops are freed.

Don’t use PMf_ONCE flag for split-to-array
Currently the PMf_ONCE flag has two purposes. It is used to indicate
that m?? must match only once. That’s what distinguishes m?? and m//
internally. The other use indicates that @x = split... modifies the
array in place.
Whenever the split op is modified to point straight to the array, the
PMf_ONCE flag is set. pp_split checks both whether there is an array
attached to the op (via a GV in the pad under threads, or a pointer
from the op to the GV under non-threaded builds) and whether the
flag is set.
This makes the flag redundant in the split case.
Removing its use here not only simplifies the code and removes redun-
dant bit-fiddling, but also makes this comment in toke.c, added by
ad639bfb6, come true:
/* This is the only point in the code that sets PMf_ONCE: */
(That was actually harmless, as it doesn’t hurt to have a stash refer-
ring to pmops that don’t use the PMf_USED flag, and the PMf_ONCE flag
is set for split way after that code is run. It is also unnecessary
for split, as that bookkeeping code in toke.c only applies to the m??
use of PMf_ONCE.)
This commit also removes a gimme != G_ARRAY check that thas been
redundant since
a6d8037e26a.

more dTHX optimizations in /win32/*
In some places, where there is a higher risk of a NULL my_perl happening
at an unknown point in the future IMO new scopes were created. In other
places dTHXa(NULL) and aTHXa were used to avoid large whitespace changes.
win32_rename and win32_getenv I determined would have no benefit from
changing them. More context passing was added to static funcs called by
win32_kill and win32_waitpid removing the need to move the dTHXs in the

[perl #115818] Don’t croak for /[.zog.]/
/[.zog.]/ produces a warning, because the POSIX syntax is not used
correctly. It must be /[[.zog.]]/.
/[[.zog.]]/ croaks, because that POSIX syntax has not been imple-
mented yet.
There is currently a croak for the former, too, even though it is
the latter syntax that is forbidden. There is no reason to forbid
the former.
The reason for warning is that /[.zog.]/ is a regular character
class (equivalent to [.zog]), so it might not do what the programmer
intended. If that is why we warn, it doesn’t make sense to croak.
After all, perl is only guessing that the programmer *might* have made
a mistake.
This makes /[.foo.]/ similar to /[:foo:]/, which warns and then acts
like /[:fo]/.
