pmc2c ATTR type parsing is naive

[Infinoid]

pmc2c can't handle an attr declaration that looks like:

    ATTR void (*custom_free_func)(void *ptr, void *priv);

cotto++ tells me this stuff is at lib/Parrot/Pmc2c/Parser.pm around line 133. I'm creating this ticket just so I won't forget about it.

a first attempt to fix ATTR parsing, causes some test failures

I've uploaded a first draft of a patch to fix this issue and allow arbitrary function pointers to be used as ATTR types. Unfortunately, this patch causes a few test failures that I haven't figured out yet.

Thanks to help from Infinoid++ I found the remaining problems, fixed them, and committed in r38353.
