Replace gv_fetchmethod() with a macro to call gv_fetchmethod_autoload()
with the extra TRUE argument.

[ 25895]
Replace hv_iternext() with a macro that calls hv_iternext_flags with
an extra 0 argument. Move the old body to mathoms.c

[ 25897]
Replace hv_magic() with a macro to call sv_magic() directly. Move the
old body to mathoms.c

[ 25898]
init_i18nl14n is a mathom.

[ 25900]
save_hints is a mathom.

[ 25901]
Functions that die aren't exactly well used code.
(ck_retarget, oopsCV, pp_padany, pp_threadsv, pp_mapstart)

[ 25903]
Replace is_utf8_string_loc() with a macro that passes the extra 0
argument to is_utf8_string_loc(). Correct the description of its
parameters in its POD.

[ 25905]
Replace uvuni_to_utf8() with a macro that passes the extra 0 argument
to uvuni_to_utf8_flags(). Move the old body to mathoms.c

[ 25906]
Given that sv_nosharing performs the same function as sv_nolocking
and sv_unnolocking (ie sweet FA), we might as well use the 1 function
to initialise all 3 variables, and elimiate the other two.
For some reason all 3 are listed as being in the public API. Daft.

[ 25907]
Perl_is_utf8_* share a lot of common code. Pull that out into a new
function S_is_utf8_common.

[ 25909]
is_utf8_alnum() and is_utf8_alnumc() can use is_utf8_common() too.

[ 25910]
const const bad bad.
gcc bad bad too, because it didn't grumble one bit. (or two, for that
matter).

[ 25911]
perlsio_binmode() is pretty much a mathom on UNIX platforms, but it is
used on Cygwin, at least.

[ 25916]
is_utf8_string_loc() is now a macro, don't use its Perl_-prefixed form

[ 25918]
Fixed threaded builds following change 25916

[ 25921]
uvchr_to_utf8() and utf8n_to_uvchr() are mathoms on ASCII based
systems, and not on EBCDIC, so some more thinking is going to be
needed here.

[ 25926]
A more elegant way to deal with utf8n_to_uvchr() and utf8n_to_uvuni().

[ 25946]
This should clear up 'Perl_do_exec' undefined; warnings on win32

[ 25947]
This *really* should clear up Win32's Perl_do_exec undefined warnings
