Make perls compiled with -Accflags=-DPERL_DEBUG_READONLY_COW to turn

We do this using mmap to allocate memory and then mprotect to mark

We have to do this at the safesysmalloc level, because some code does
SvPV_set with buffers it allocates on its own via safemalloc().
Unfortunately this means many things are allocated using mmap that
will never be marked read-only, slowing things down considerably, but
I see no other way.
Because munmap and mprotect need to know the length, we use the
existing sTHX/perl_memory_debug_header mechanism used already by
PERL_TRACK_MEMPOOL and store the size there (as PERL_POISON already
does when PERL_TRACK_MEMPOOL is enabled). perl_memory_debug_header is
a struct positioned at the beginning of every allocated buffer, for
tracking things.

[perl #118817] avoid using 2 handles to write to the debug output
Previously the tests were run with the following config:
NonStop=0 TTY=db.out LineInfo=db.out
This meant that the debugger would write the prologue, command prompts
and their results and the epilogue to one handle, and any line trace
information to the second handle. Since those handles didn't share a
file position, the line trace info would overwrite the prologue, and
the epilogue would overwrite part of the line trace info.
When TTY=vt100 on Redhat systems this made the epilogue just long
enough to overwrite the line trace data that a test matched against,
causing the test to fail.
To fix this, I avoided setting LineInfo:
NonStop=0 TTY=db.out
and since LineInfo defaults to using the TTY handle, both types of
content are written to db.out *without* overwriting each other.
Unfortunately this broke some other tests, since the command prompts
which were overwritten by line trace information are now mixed in with
the line traces - I've modified the tests that failed to account for
the included command lines.

Don't multiply define _new_invlist_C_array.
It's now an external function in regcomp.c, so it doesn't need to
also be defined in re_comp.c. And in fact it mustn't be as the VMS
linker warns with:
%ILINK-W-MULDEF, symbol PERL__NEW_INVLIST_C_ARRAY multiply defined
module: RE_COMP
which becomes a run-time error.

regexec.c: Don't skip trying POSIX class if [] has individ char

PATCH: [perl #120675] Unexpected tainting via regex using locale
introduced a bug in which under /li matching a bracketed character class
that contains both characters and POSIX classes would skip matching
against any POSIX class. The example in the added test illustrates the
problem:
"h" =~ /[g\w]/li; # Failed! in C locale

fix missing _rotl64 symbol on Visual C 2003
Due to a bug in the CRT (msvcr71.dll), these 2 functions are not defined
in any lib Perl can use (static link CRTs dont apply, Perl only uses DLL
CRTs), but they are available as intrinsics. This solves a link error
about missing symbol __rotl64 in hv.obj, from usage in hv_func.h, on 32 bit
USE_64_BIT_INT VC 2003 builds. _rotr64 is included for completeness. This
fix is filed as [perl #120925].

Merge branch into blead to compile into C all POSIX classes...
This series of commits creates C compile time inversion lists for the
remaining POSIX classes that didn't have them, plus IDStart and IDCont
which are used with the 'utf8' pragma, plus one that is used for
compiling regular expressions.
This should allow faster start up times for Perl programs that use these
on code points 256 and above, while having negligible effect on programs
that don't. It also leads to some simplification of core code, and
removal of two arrays of smaller inversion lists.

regexec.c: Use compiled-in POSIX definitions
This changes the regex engine to not go out to the disk when needing to
find the definitions of POSIX classes, but to use the compiled-in ones
introduced earlier in this commit series.

IDStart and IDCont no longer go out to disk
These are the base names for various macros used in parsing identifiers.
Prior to this patch, parsing a code point above Latin1 caused loading
disk files. This patch causes all the information to be compiled into
the Perl binary.

isWORDCHAR_uni(), isDIGIT_utf8() etc no longer go out to disk
Previous commits in this series have caused all the POSIX classes to be
completely specified at C compile time. This allows us to revise the
base function used by all these macros to use these definitions,
avoiding reading them in from disk.

Move initialization of PL_XPosix_ptrs[] to perl.c
This was performed unconditionally in regcomp.c. However, future
commits will use this from other code. Almost all (but not completely
all) Perl code uses regular expressions, so only rarely will this small
amount of initialization be performed when it currently isn't.

Rmv PL_Posix_ptrs
Previous commits in this series have removed all uses of this global
array. This completely removes it.
Since it is a global, consideration need be given to possible uses of it
outside the core. It has never been externally documented, and is an
opaque structure whose internals have changed with every release. The
functions used to access it are almost all static to regcomp.c; those
few that aren't have been hidden from all but the few .c files that need
to have access to them, via #if's.

regcomp.c: Rmv remaining uses of PL_Posix_ptrs
Previous commits have removed all but a few uses of PL_Posix_ptrs. This
removes the rest. ASCII is the same whether over all code points, or
just the ASCII range, so we can substitute the version for all code
points. There is an extra intersection introduced by this commit during
the construction of a synthetic start class under /a and /aa, but the
performance hit should be negligible.
