Teach autodoc.pl about 'o' functions.

That is, functions with no #define foo Perl_foo. I'm not certain this is
the right way to do it, as I don't really understand which flags autodoc
honours from which places; currently, it's necessary to put the 'o' flag
on the =for apidoc line or it will be ignored.
