This complies with the perlcritic policy
Subroutines::RequireFinalReturn, which is a severity 4 policy. Since we
only currently check at severity level 5, the policy is raised to that
level until we move to level 4 or lower, so that any new infringements
will be caught.
A small cosmetic piece of tidying of the pgperlcritic script is
included.

Fix all perlcritic warnings of severity level 5, except in
src/backend/utils/Gen_dummy_probes.pl, which is automatically generated.

Avoid compile problems with defines being redefined after the removal of
the #if blocks.
Change script to use shell functions for simplicity.
This is slower than the original coding but avoids the problem of
including files in an unpredictable order. Aside from being more
trustworthy, we can get rid of some exclusions that were formerly
made for what turn out to be ordering or re-inclusion problems.
I also modified it to include libpq's exported files in the check.
ecpg should be included as well, but I'm unclear on which ecpg .h
files are meant to be included by clients.
This alters various incidental uses of C++ key words to use other similar
identifiers, so that a C++ compiler won't choke outright. You still
(probably) need extern "C" { }; around the inclusion of backend headers.

Also add a script cpluspluscheck to check for C++ compatibility in the
future. As of right now, this passes without error for me.
compiler warning, specifically #ifdef or #if defined tests on symbols
that are defined in a file not included. The results are a bit noisy
and require care to interpret, but it's a lot better than no tool at all.
