printf: Fix up %p to %pP
In order to avoid landmines later with future extensions to %p,
disallow %p by itself. The danger is that we'll have something
like: printf("%pFOO", myptr), and then later will add a %pF
extension, but miss this printf (maybe the string is split, maybe
it's just missed).
Missing a conversion during extension is worse than just seeing a
print like <ptr_val>OO, since %pF likely reaches through the
pointer and interprets its contents according to whatever F means.
Convert existing uses of %p to %pP, so they're explicitly printing
a pointer value, giving us flexibility to extend in the future.
