Make 4-arg substr check SvUTF8(target) after stringfying

resulting in malformed UTF8. Both tests added produced malformed utf8
strings before this commit.
Simply moving this:
if (!DO_UTF8(sv))
sv_utf8_upgrade(sv);
after the stringification is not enough to fix this, as the string
retrieved will be out of date after we do an upgrade. To avoid
stringifying twice, we use SvPV_force if there is a replacement. This
means rearranging if() blocks a little.
The use of SvPV_force also means that string overloading is no longer
called twice on the target scalar. This rearrangement also means
that targets upgraded to utf8 are no longer exempt from the refer-
ence warning. (Oh, and the test for that warning was not testing any-
thing in its no warnings test, because the target was no longer a ref-

Stop pos from panicking when overloading changes UTF8ness
This touches on issues raised in tickets #114410 and #114690.
If the UTF8ness of an overloaded string changes with each call, it
will make magic_setpos panic if it tries to stringify the SV multiple
times. We have to avoid any sv-specific utf8 length functions when
it comes to overloading. And we should do the same thing for gmagic,
too, to avoid creating caches that will shortly be invalidated.

Make sv_len_utf8 return a character count as documented
Brought up in ticket #114690.
sv_len_utf8 does not make sense. It assumes that the string is UTF-8.
If it is not, it just does the wrong thing. For magical variables, it
expects mg_length to return the number of characters, but it would
only sometimes do that until the previous commit, which restored it to
returning bytes for all scalars.
Since you have to know already that a string is in utf8 before you
can call sv_len_utf8, but sv_len_utf8 might call get-magic which will
change the utf8-ness, it really makes no sense as an API. Up till
now, it has been consistently buggy with any magic scalars.
So I have changed sv_len_utf8 to do exactly what the documentation
says: return the number of characters.
This also causes an existing buggy code path in sv_len_utf8_nomg to be
reached (SvCUR without checking SvPOK), so this fixes that too.

Deprecate mg_length; make it return bytes
mg_length returns the number of bytes if a scalar has length magic,
but the number of characters otherwise.
sv_len_utf8 used to assume that mg_length would return bytes. The
first mistake was added in commit
b76347f2eb, which assumed that
mg_length would return characters. But it was #ifdeffed out until
commit
ffc61ed20e.
Later, commit
5636d518683 met sv_len_utf8’s assumptions by making
mg_length return the length in characters, without accounting for
sv_len, which also used mg_length.
So we ended up with a buggy sv_len that would return a character
count for scalars with get- but not length-magic, and a byte count
otherwise.
In the previous commit, I fixed sv_len not to use mg_length at all. I
plan shortly to remove any use of mg_length (the one remaining use is
in sv_len_utf8, which is currently not called on magical values).
The reason for removing all calls to mg_length is that the returned
length cannot be converted to characters without access to the PV as
well, which requires get-magic. So length magic on scalars makes no
sense since the advent of utf8.
This commit restore mg_length to its old behaviour and lists it as
deprecated. This is mostly cosmetic, as there are no CPAN users. But
it is in the API, and I don’t know whether we can easily remove it.

Make pos less volatile when UTF8-ness can change
This was brought up in ticket #114690.
pos checks the length of the string and then its UTF8-ness. But the
UTF8-ness is not updated by length magic. So it can get confused if
simply stringifying a match var happens to flip the UTF8 flag:
$ perl -le '"\x{100}a" =~ /(..)/; pos($1) = 2; print pos($1); "$1";
print pos($1)'
2
1
$ perl -le '"\x{100}a" =~ /(.)/; pos($1) = 2; print pos($1); "$1"; print
pos($1)'
1
Malformed UTF-8 character (unexpected end of string) in match position
at -e line 1.
0
As pointed out in that ticket, length magic on scalars cannot work
properly with UTF8, so stop using it.

Historically the regex engine has assumed that any string passed to it

ways.
First, when at the end of string, the main loop of regmatch() still reads
in the 'next' character (i.e. the character following the end of string)
even if it doesn't make any use of it. This precludes using memory mapped
files as strings for example, since the read off the end would SEGV.
Second, the matching algorithm often required the trailing character to be
\0 to work correctly: the test for 'EOF' was "if next char is null *and*
locinput >= PL_regeol, then stop". So a random non-null trailing char
could cause an overshoot.
Thirdly, some match ops require the trailing char to be null to operate
correctly; for example, \b applied at the end of the string only happens
to work because the trailing char (\0) happens to match \W.
Also, some utf8 ops will try to extract the code point at the end, which
can result in multiple bytes past the end of string being read, and
possible problems if they don't correspond to well-formed utf8.
The main fix is in S_regmatch, where the 'read next char' code has been
updated to set it to a special value, NEXTCHR_EOS instead, if we would be
reading past the end of the string.
Lots of other random bits in the regex engine needed to be fixed up too.
To track these down, I temporarily hacked regexec_flags() to make a copy
of the string but without trailing \0, then ran all the t/re/*.t tests
under valgrind to flush out all buffer overruns. So I think I've removed
most of the bad code, but by no means all of it. The code within the
various functions in regexec.c is far too complex to be able to visually
audit the code with any confidence.

regmatch() annotate ops and separate out branches
Annotate each 'case OP:' in the main switch in regmatch() to show
what regex pattern this implements. About half the ops had already been
done. Also add a blank line between each 'case' statement for readability.

regmatch(): do nextchr=*locinput at top of loop
Currently each branch in the main regmatch() loop is responsible
re-initialising nextchar to UCHARAT(locinput) if locinput is modified.
By adding
nextchr = UCHARAT(locinput);
to the head of the loop, we can remove most of the nextchar assignments
in the individual branches. We lose slightly for the zero-width assertions
like \b which will re-read the same nextchar, but this will make it
easier to handle non-null-terminated strings.

regmatch(): consolidate locinput++
There are several places in the code that increment locinput by 1 char
(which may or may not be 1 byte) then update nextchr.
Consolidate these into a single code block with the others goto'ing it.
This actually reduces the code more than it appears, since the CCC_TRY*
macros expand into several branches, each of which repeatthe
increment code.

Stop declaring non-exported externs to non-core XS modules [perl #114516]
Hide the perl.h declarations of gete?[ug]id and getlogin on Win32 since
they are already declared in win32/win32.h, nearer to their definitions
(stub functions for UNIX compatibility) in win32/win32.c.
Also only declare them, and kill(pg)?, sbrk, chown and mkstemp, under
PERL_CORE anyway since they are not exported: including declarations for
non-exported functions just hides compiler errors about the symbols being
undefined, which doesn't help when trying to fix subsequent errors from
the linker about the symbols being unresolved. (Actually, all but sbrk,
chown and mkstemp get indirected through the perlhost layer normally
anyway, but it doesn't hurt to still hide the declarations, and helps in
the case of PERL_IMPLICIT_SYS not being defined, where only kill is
redefined to something which is exported.)
The declarations of the set[ug]id stub functions remain for now because
those two symbols are currently exported.

A better fix for leaking array assignment
Instead of filling up the mortals stack with as many SVs as there are
elements, just call get-magic before creating the new SV.
(This is not so easy for hashes, as we have keys as well, and
