utf8.h: White-space only

I believe this makes the macro easier to read
utf8.c: Silence Win32 compiler warnings

The Win32 compiler doesn't realize that the values in these places can
be a max of 255.  Other compilers don't warn.
Revert "Optimise if/unless wrt OP_AND/OP_OR/OP_DOR. Also optimise OP_OR/OP_DOR chains."

PATCH: [perl #120041] regcomp.c missing parens and broken STCLASS

This was caused by a problem in commit
43a64b8b430604bd4d76fd256a5babdccaf0ab2b
which was masked by problems in commit
a0dd42312a1f26356d2fdf49656e45b77c2cefb5.

The first commit deleted a line it shouldn't have.  I thought that a
variable wasn't modified before reaching that line, but it turns out it
was because another variable is set to point to its address, and was
modified inside a subroutine call.  The other two lines deleted in the
first commit are ok to have deleted.

The second commit masked the problems of the first by omitting some
necessary grouping parentheses, which caused things to not work as
intended, and we didn't have a good test case in our suite to find this
problem.  (Thanks to Lukas Mai for spotting the problem and submitting a
test case.)
regcomp.c: Fix up confusing comment

This was discussed as part of [perl #120041].
Update Getopt-Long to CPAN version 2.42

Changes in version 2.42
-----------------------

* Fix bug https://rt.cpan.org/Ticket/Display.html?id=88707
Update CPAN-Meta-YAML to CPAN version 0.010

  [DELTA]

0.010     2013-09-23 13:11:20 America/New_York

  - Generated from ETHER/YAML-Tiny-1.55.tar.gz

  - Fix broken test when copying from YAML-Tiny

  - updated Makefile.PL logic to support PERL_NO_HIGHLANDER

0.009     2013-09-23 10:16:19 America/New_York

  - Generated from ETHER/YAML-Tiny-1.55.tar.gz

  - Makefile.PL will use UNINST=1 on old perls that might have
    an old version incorrectly installed into the core library path
Update Parse-CPAN-Meta to CPAN version 1.4409

  [DELTA]

1.4409    2013-09-23 13:17:18 America/New_York

    - updated Makefile.PL logic to support PERL_NO_HIGHLANDER

1.4408    2013-09-23 11:06:35 America/New_York

    [FIXED]

    - Installation on Perls < 5.12 will uninstall older versions installed
      due to being bundled with ExtUtils::MakeMaker
Update CPAN-Meta-Requirements to CPAN version 2.125

  [DELTA]

2.125     2013-09-23 14:51:14 America/New_York

    - Better fix than 2.123.  On old perls, rather than install into
      'core', we continue to install into the proper 'site' library,
      but force UNINST=1 when necessary to remove stale copies
      from ExtUtils::MakeMaker

  - Installation on Perls < 5.12 will uninstall older versions installed
    due to being bundled with ExtUtils::MakeMaker
Regen META files for CPAN::Meta update
Fix ext/File-Glob/t/threads.t filenames for VMS.

As noted in

http://www.nntp.perl.org/group/perl.perl5.porters/2013/09/msg208134.html

zero-length extensions always get a trailing dot on VMS, and the
easiest workaround is to always use an explicit extension.

Porting/Maintainers.pl - Remove most MAINTAINER fields

Remove the MAINTAINER field if it was 'p5p' (or 'blead', which was the case for
Unicode::UCD, presumably in error) or if there is a DISTRIBUTION field. Only a
few MAINTAINER fields are now left, for modules with non-'p5p' maintainers but
no CPAN distribution. For modules now having no MAINTAINER field, the maintainer
is understood to be either the Perl 5 Porters if there is no DISTRIBUTION field
or the UPSTREAM field is 'blead', or else the CPAN author whose PAUSE user ID
forms the first part of the DISTRIBUTION value.

Set up a legacy MAINTAINER field for backwards compatibility with existing
functionality in Porting/Maintainers, Porting/corecpan.pl and
Porting/corelist.pl.

The latter program now omits modules such as Attribute::Handlers from %upstream
and %bug_tracker in CoreList.pm because the MAINTAINER is now understood to be
'p5p' since the UPSTREAM field is 'blead'. Previously it was included because a
non-'p5p' MAINTAINER was given, but that was really at odds with UPSTREAM being
'blead'.
Porting/Maintainers.pl - Use PAUSE user IDs

Since we now encourage the use of the DISTRIBUTION field to find the PAUSE
user ID of the maintainer rather than explicitly listing most maintainers,
it makes sense to also use PAUSE user IDs where possible for the few
MAINTAINERS that are still given explicitly.
Porting/Maintainers.pl - Consistent quotes
Porting/Maintainers.pl - No need to list IGNORABLES as EXCLUDED
Porting/corelist.pl - Fix breakage since commit c676c8385f
