Add a new function newSVpvn_flags(), which takes a third parameter of
flag bits. Right now the only flag bit is SVf_UTF8, which will call
SvUTF8_on() on the new SV for you. Provide a wrapper newSVpvn_utf8(),
which takes a boolean, and passes in SVf_UTF8 if that is true.
Refactor the core to use it where possible. It makes the source code
clearer and smaller, but seems to be swings and roundabouts on object

Replace our assert-which-can-be-caught-by-eval with the real deal from
the standard C library. Make ours available as Perl_assert(), if you
really want that.
assert() is only #include'd if you compile with -DDEBUGGING.

Remove the definitions of Null(), Nullch, Nullfp, Nullsv and PL_na
when PERL_CORE is defined. (Which, "obviously", is only in code
within the perl source tree, which we control). Nullop remains, and
would be moderately invasive to remove.

Hateful software that sends my cursor keys as packets that can get
split, and more hateful software that decides that split packets
means not-a-cursor-key.

By moving the "can't upgrade downwards" croak() in Perl_sv_upgrade()
after the type changing logic, we allow sv_upgrade() from SVt_NV to
SVt_IV to "work" (SVt_NV beomes SVt_PVNV in the type changing logic)
which simplifies the code for Perl_sv_setiv() slightly.
