  2. regen/embed.pl: Handle m with p flags 

    Prior to this commit these were illegal.

This causes embed.fnc to generate macro 'Perl_foo' #defined to be  macro
'foo'.  If the macro name is all upper case, we instead get macro
'PERL_FOO' for 'FOO'.  This could be used to easily convert existing
macros into having long names should some become a name space pollution
problem.

This also documents in embed.fnc, under the 'm' flag discussion, how to
use this instead of placing things in mathoms.c, or creating stub
functions.
