[PATCH 10/12] packfile.h: drop extern from function declarations




As CodingGuidelines recommends, we do not need an "extern" when
declaring a public function. Let's drop these. Note that we leave the
extern on report_garbage(), as that is actually a function pointer, not
a function itself.

I hesitated on this one, because it does have a minor conflict with pu.
But I just couldn't bring myself to add a new extern, nor to stick a
non-extern one amidst a bunch of others.
