stop ~ in format modifying format string
Currently, the format parser converts ~ or ~~ in a format string into
blank spaces. Since the previous-but-one commit, it only does it in a copy
rather than the original string, but this still defeats the "if the string
is the same don't recompile" mechanism.
Fix this by leaving the ~ alone in the format string, but instead cause
FF_LITERAL to convert '~' to ' ' when appending to the target.
Also, in S_doparseform(), improve the processing of '~~': previously
it only skipped one '~', and processed the second '~' on the next loop;
this happened to work, but it's less unexpected to process both chars at
once.
I've also added some tests, but these don't actually test whether the
format gets re-compiled: I couldn't think of a way to do that short of
checking the output of perl -Df. Instead the tests I added were based
around making sure I didn't break anything related to ~~ formatting.
I also improved the description string for some of the existing tests.

RT #91032: formline: bugs with non-string formats
When the format SV used by formline isn't a simple POK (such as
ties, overloads, or stringified refs), many many things go wrong,
and SEGVs ensue.
Originally, pp_formline forced the SV to a PV, and then assumed it could
rely on the resulting SvPVX value. Recent commits fixed this to
skip the force (good), but then broke things such as:
* in the absence of POK or pPOK, $^A was grown by 0 bytes rather than the
length of the format, so the buffer overran;
* the compiled format stored indexes into the original format string
to refer to chunks of content text and the like. If there's no real
SvPVX around, that's bad.
* Stuff like tie and overload could return different format strings on
each get, but the format would not be re-compiled (but would index into
the new string anyway)
Also, the format compiler would convert strings like '~~' into blanks
in the original format SV.
The easiest way to fix all these is to save a copy of the original string
at the time it is compiled. This can conveniently be stored in the mg_obj
slot of the fm magic (the compiled format already goes in mg_ptr).
This way we're always guaranteed to have an unadulterated copy of the
string to mess with.
Also, the ~~ self-modification now happens to the copy rather than the
original.
Now each time formline is called, we also compare the current value of the
SV with the stored copy, and if it's changed (e.g. tie with a FETCH that
returns different values each time), then we recompile.
Note that the recompile test is currently defeated by the ~~ modification,
so re-compiles unnecessarily (but safely) in that case. A fix for that is
coming next.

That's not "in other words", these are totally different

Use L<> rather than C<> in the Updated Modules section of perldelta.
Previous perldeltas have been inconsistent with each other as to whether to
use L<> to C<> (but internally consistent). perldelta5140.pod uses L<>, which
is more useful, as it provides a direct link to fuller documentation at the
point where the reader is likely to want to follow it.
Switch the two existing entries from C<> to L<>, and update the perldelta
template to suggest L<>.

[perl #85026] Deleting the current iterator in void context
Looking at the delete code I see another strange thing. If the delete
of the current iterator is done with the G_DISCARD flag, the corres-
ponding value is not freed and survives until the lazy deleted entry
gets removed on the next hash iteration. This is easily demonstrated
like this:
perl -wle '
sub DESTROY { print "DESTROY" }
%a=(a=>bless[]);
each %a;
delete $a{a};
print "END"
'
This prints:
END
DESTROY
notice the difference with:
perl -wle '
sub DESTROY { print "DESTROY" }
%hash = (a => bless[]);
each %hash;
$dummy = delete $hash{a}; $dummy = 0;
print "END"
'
This prints:
DESTROY
END
This is easily solved by always replacing the deleted entry value with
&PL_sv_placeholder. It actually simplifies the code a bit except for the
fact that the mro_method_changed from free_hash_ent now has to be done
in hv_delete

[perl #85026] deleting elements in a HASH iterator
Internally a perl HASH is an array of single linked chains of entries.
Deleting an element means removing the correct chain entry by replacing
the pointer to the removed entry with a pointer to the next entry and
then freeing the deleted entry
However, if the deleted element is the current entry the deleted entry
is kept after removing it from the chain and the LAZYDEL flag is set.
Only on the next iteration is the element actually removed and the
iterator is set to the next entry.
However, if you delete the current iterator and then delete the next
element in the same chain the "next" pointer of the iterator is not
updated because the iterator is not on the chain anymore. That means
that when the next iteration looks up the iterator next pointer it
will point to the freed memory of the second element.
This patch fixes the places where the delete is done. Drawback is that
you may never forget to do the lazydel fixup in at any place where the
entry chain gets shortened.
