include: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Replace Sun Industry Standards Source License for Sun RPC code with a
3-clause BSD license as specified by Oracle America, Inc. in 2010.
This license change was approved by Wim Coekaerts, Senior Vice
President, Linux and Virtualization at Oracle Corporation.

__BEGIN_DECLS and __END_DECLS in cdefs.h take care of the
__cplusplus mangling issues so most of the definitions
were redundant.

In the few places where they were not redundant we should
use BSD style instead of the guards used upstream.

Fix RPC headers for C++

C++ mangling will cause trouble with variables like __rpc_xdr

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add compatibility functions for the AF_LOCAL RPC transport stuff
that used to live in RPC 4.0. This is needed for yppasswd and
rpc.yppasswdd to work correctly. Patch supplied by Martin Blapp.

Add a new clnt_control() request `CLSET_CONNECT' that controls
whether or not connect(2) is used for UDP client sockets. The default
is not to connect(), so existing clients will see no change in
behaviour.

The use of connect(2) for UDP clients has a number of advantages:
only replies from the intended address are received, and ICMP errors
pertaining to the connection are reported back to the application.

Add a CLSET_ASYNC command, which allows us to (ab)use the clnt_dg transport
to make asynchronous RPCs. This is needed to help fix ypbind, which can no
longer override the clnt_dg_call() method (formerly the clntudp_call()
method) due to all the internal descriptor locking code in TI-RPC. Turning
on this flag allows us to send an RPC request, then return immediately,
and handle a reply later, rather than being forced to do the request
and reply in a single function call.

Also fix a byte ordering bug: when clnt_dg_call() increments the XID
prior to transmitting a request, it uses the raw value, which is wrong.
The XID is stored in network byte order, i.e. big-endian. The CLSET_XID
and CLGET_XID commands in clnt_dg_control() use ntohl()/htonl() to get
the byte ordering right, but because clnt_dg_call() does not do this,
using CLSET_XID/CLGET_XID doesn't actually work, unless you're on a
big endian host, which we aren't (yet). Fix clnt_dg_call() to byte swap
properly when doing the increment.

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.

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.

This commit was manufactured by cvs2svn to create branch 'WPAUL'.

Remove trailing whitespace.
