Zack Weinberg 82f43dd2d1 Include shlib-compat.h in many sunrpc/nis source files.
Every file that uses libc_hidden_nolink_sunrpc or
libnsl_hidden_nolink_def needs to include shlib-compat.h.  Currently,
most of them are getting it via stdio.h, because libio.h refers to
SHLIB_COMPAT when _LIBC is defined, so it includes shlib-compat.h.  My
experimental patch to not install libio.h breaks that chain; stdio.h
no longer pulls in libio.h even for internal users.

Accordingly, this patch adds #include <shlib-compat.h> to many files
in sunrpc/ and nis/.  There are also a small number of really obvious
fixups to includes that caught my eye while proofreading the patch -
not including headers twice in a row, not worrying about portability
to Ultrix anymore, sort of thing.
