Subject: [PATCH] pextlib1.0: Sort includes, declare getline(3)

Linux requires stdio.h for getline(3), and fails without it. glibc >=
2.10 defines getline(3) in _XOPEN_SOURCE >= 700. We ship a getline.h
compat implementation, but that doesn't get included unless HAVE_GETLINE
isn't defined, which isn't the case on Linux.
