t/porting/readme.t: Check Porting/README.pod consistency

This is a slightly expanded (or bloated) version of the patch
Dennis Kaarsemaker <dennis@kaarsemaker.net> submitted.
Fix Porting/README.pod so it passes its new test.

Added entries for sync-with-cpan and README.pod itself.  Rearranged
entries to be sorted consistently.
MANIFEST: add t/porting/readme.t

pad.c, S_cv_clone: Maintain the utf8-ness of the cloned cv

Because of a missing SvUTF8_on() in cv_clone(), these two were different:

    use utf8;
    eval "   sub foo ($;\x{30cd});"
    eval "my sub foo ($;\x{30cd});"

Because the lexical version would lose the UTF8 flag in the
prototype.
make sure the prototype actually matches

because:

a) I think it better demonstrates the fix, the following failed without
the patch:

./perl -Ilib -le 'my $proto = "\x{30cd}"; eval "sub f($proto) {}"; print prototype(\&f); print prototype(\&f) eq $proto'

b) I can envision bugs that might preserve UTF-8 but mis-manage the content
Reinstate UTF8f

This format string allows char*s to be interpolated with the
utf8ness and length specified as well, avoiding the need to create
extra SVs:

Perl_croak(aTHX_ "Couldn't twiggle the twoggle in \"%"UTF8f"\"",
                  UTF8fARG(is_utf8, len, s));

This is the second attempt.

I screwed up in commits 1c8b67b38f0a5 and b3e714770ee1 because
I didn’t really understand how varargs functions receive their
arguments.

They are like structs, in that different members can be different
sizes.  So therefore both ends--the caller and the called--*must* get
the casts right, or the data will be corrupted.

The main mistake I made was to use %u in the format for the first
argument and then retrieve it as UV (a simple typo, I meant unsigned
int or U32--I don’t remember).

To be on the safe side, I added a UTF8fARG macro (after SVfARG), which
(unlike SVfARG) takes three arguments and casts them explicitly, mak-
ing it much harder to get this wrong at call sites.
op.c:cv_ckproto_len_flags: do null checks first

Checking local variables for nullness is faster than calling ckWARN_d,
which involves a function call.

plus one typo fix
op.c: Remove dummy code from const_sv_xsub

This was added in commit 9cbac4c7 with no explanation.  It has been
#ifdeffed out since it was added.  That commit was supposedly just for
compiler warnings.  I think this was something else the author was
playing with that got combined in the same patch by mistake.
Revert "Make t/podcheck.t less sensitive"

This reverts commit f26da014a698383ac348973050af3e754752e6ab.

do not worry about long verbatim lines w/o env var

To run these tests, set PERL_POD_PEDANTIC in the environment.

This needs further testing, at least, to ensure that it behaves correctly
when regenerating the known problem files.
Run the pedantic checks when regenerating the database

Make the two checks of possible poor uses of C<>
pedantic checks.

Allow --pedantic to turn on those tests in addition to

op.c: Suppress compiler warning

Sorry, commit 08aff5359 was not quite ready and I pushed it too soon.

The purpose of the if block that it removed was to suppress a warn-
ing about an unused variable, but it was a very strange way of accom-
plishing that.

We have a much simpler way that takes only one line and expresses its
intent clearly.
