Can you rename it to something with a more obvious name? "p3" doesn't
mean anything to me. Perhaps "lib/external" ?

Please update lib/, which is there to update
some of these libraries. (I've got a pending patch to make it update zlib)

Can you move each library in a separate commit? Git doesn't deal well
with moves of lots of files unless you specify the magic options (see
e.g. the output of "git log lib/zlib").
