regcomp.c: Use colors for -Dr metanotation
Use a different color for the metanotation than the code points being
output under Debugcolor. The default is to have stand out mode for the
code points, and not for the meta.

Add environment variable for -Dr: PERL_DUMP_RE_MAX_LEN
The regex engine when displaying debugging info, say under -Dr, will elide
data in order to keep the output from getting too long. For example,
the number of code points in all of Unicode matched by \w is quite
large, and so when displaying a pattern that matches this, only the
first some number of them are printed, and the rest are truncated,
represented by "...".
Sometimes, one wants to see more than what the
compiled-into-the-engine-max shows. This commit creates code to read
this environment variable to override the default max lengths. This
changes the lengths for everything to the input number, even if they
have different compiled maximums in the absence of this variable.
I'm not currently documenting this variable, as I don't think it works
properly under threads, and we may want to alter the behavior in various
ways as a result of gaining experience with using it.

This branch will only be true if the answer to the previous branch was
also true, so can just move it to within that to avoid an unnecessary
test.

regcomp.c: Clarify -Dr output under /l
It is now redundant to indicate that an ANYOF node is for locale, as the
regnode type ANYOFL now clearly indicates that. But also sometimes the
node is only vaid if the runtime locale is a UTF-8 one. That was not
clearly indicated.

regcomp.c: optimization for qr/[...]/il
Certain matches are calculated as being legal only when the current
execution time local is a UTF-8 one. However, a character class can
have multiple components (and usually does), and some of those components
may be duplicates of some of these matches, and be valid regardless of
the locale. This commit removes them from the tentative list, and if it
goes to zero, clears it. This will improve execution time slightly.

regcomp.c: Avoid a segfault
I stumbled across this in adding more code elsewhere, so I don't know
how to trigger it. This is in the intersection routine for two
inversion lists. The corresponding union code correctly handles the
case when the input is NULL, so just copy that to here.

Change private function to static
This function was used outside the file it contains, but was only
defined (by #ifdef's) for those few internal core files for which it was
needed. Now all those uses have gone, save for the one file. Better to
make it static so no one can circumvent those #ifdef's.

regcomp.c: Fix -Dr bug
It was using a wrong length calculation, which under some circumstances
caused the output to include extra bytes. Also I added comments, and

PATCH: [perl 127537] /\W/ regression with UTF-8
This bug is apparently uncommon in the field, as I was the one who
discovered it. It requires a complemented posix class, like \W or \S,
in an inverted character class, like [^\Wfoo] in a pattern that also has
a synthetic start class generated by the regex optimizer for it .
The fix is trivial.

regcomp.c, toke.c: swap functions being inline static
grok_bslash_x() is so large that no compiler will inline it. Move it to
dquote.c from dq_inline.c. Conversely, move form_octal_warning() to
dq_inline.c. It is so tiny that the function call overhead is scarcely
smaller than the function body.
This also moves things in embed.fnc so all these functions. are not
visible outside the few files they are supposed to be used in.
