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.

  New configure option --enable-obsolete-rpc makes the deprecated RPC
  headers and functions available at compile time as they were before
  version 2.14.  This option will be removed at some time in the future
  after the TI-RPC library becomes fully sufficient for the needs of
  existing applications.

This reverts commit ab09b221594f12d90a63d29cbf5488d91f39d3f3.

The lawyers now say the copy in glibc isn't contained in the
agreement.
