MFC r258578, r258580, r258581 (by hrs):
Replace Sun RPC license in TI-RPC library with a 3-clause BSD license
with the explicit permissions.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

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.

Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

Bring in required TLI library routines to support this.

Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.

This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).

The submitter has agreed to continue on and bring us up to the
1999 release.

Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.

Many userland updates were done to bring the code up to par with
the recent RPC API.

There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.

While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.

New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.

Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.

Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

$Id$ -> $FreeBSD$

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.

First commit of a series of cleanups for the libc rpc code which has been
suffering a bad case neglect for the last few years.

- Add full prototypes, including to function pointers.
- Make the wire protocols 64-bit type safe, eg: 32 bit quantities are
int32_t, not long. The orginal rpc code was implemented when an int
could be 16 bits.

Obtained from: a diff of FreeBSD vs. OpenBSD/NetBSD rpc code.

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

Remove trailing whitespace.

Forward-declare `struct rpc_err' so that it isn't declared inside a
prototype when <rpc/clnt.h> isn't included.

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.
