rpc: convert all uid and gid variables to u_int.

Follow a similar change in Solaris and linux where the uid and
gid variables were made more similar to what the system expects.
In our case we use u_int which is what XDR can manage,

Complete revert of r239963 (from head).

The attempt to merge changes from the linux libtirpc caused
rpc.lockd to exit after startup under unclear conditions.

Reported by: David Wolfskill

MFC r239963:

Bring some changes from Bull's NFSv4 libtirpc implementation.

____

Fixed infinite loop in svc_run()
____

__rpc_taddr2uaddr_af() assumes the netbuf to always have a
non-zero data. This is a bad assumption and can lead to a
seg-fault. This patch adds a check for zero length and returns
NULL when found.
____

Changed clnt_spcreateerror() to return clearer
and more concise error messages.
____

Converted all uid and gid variables of the type uid_t and gid_t.
____

libtirpc: set r_netid and r_owner in __rpcb_findaddr_timed

These fields in the rpcbind GETADDR call are being passed uninitialized
to CLNT_CALL. In the case of x86_64 at least, this usually leads to a
segfault. On x86, it sometimes causes segfaults and other times causes
garbage to be sent on the wire.

rpcbind generally ignores the r_owner field for calls that come in over
the wire, so it really doesn't matter what we send in that slot. We just
need to send something. The reference implementation from Sun seems to
send a blank string. Have ours follow suit.
____

libtirpc: be sure to free cl_netid and cl_tp

When creating a client with clnt_tli_create, it uses strdup to copy
strings for these fields if nconf is passed in. clnt_dg_destroy frees
these strings already. Make sure clnt_vc_destroy frees them in the same
way.

Breath deep and take __P out of the system include files.

# This appears to not break X11, but I'm having problems compiling the
# glide part of the server with or without this patch, so I can't tell
# for sure.

$Id$ -> $FreeBSD$

Resolve conflicts.

Back out all of yesterdays include file changes.

Make a lot of include-files self-contained. I excluded the patches changing
int's to gid_t and uid_t - should I commit these, too?

Closes PR misc/2625.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Fix a bunch of spelling errors in the comment fields
of a bunch of system include files.

Remove trailing whitespace.

Use the header files that are compatible with the code just moved over
from 1.1.5.

Install RPC headers from include, like they always should have been.
