rpc.lockd: Explicitly cast enum nlm_stats values to enum nlm4_stats.

NLM 4 status values are a superset of the older NLM protocol so these
casts are safe while pacifying -Wenum-conversion warnings from GCC.

spdx: initial adoption of licensing ID tags.

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.

Initially, only tag files that use BSD 4-Clause "Original" license.

Actually use the loop interation limit so carefully computed on the
previous line to prevent buffer overflow. This turns out to not be
important because the upstream xdr code already capped the object
size at the proper value. Using the correct limit here looks a lot
less scary and should please Coverity.

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.

- Import the HEAD csup code which is the basis for the cvsmode work.

- Use svc_getrpccaller() rather than svc_getcaller() for using
xt_rtaddr member of SVCXPRT structure. This allows to use IPv6
address stored in "struct sockaddr_storage" in "struct netbuf".
- Output the reason of getnameinfo() error.

Make rpc.lockd bind to a reserved port, since there are NFS clients
which ignore NLM requests not coming from a reserved port.

Make this compile cleanly. It passes WARNS=2, but I haven't checked
it is so on more platforms.

When receiving NLM_GRANTED_RES or NLM4_GRANTED_RES lock granted messages
from the NFS server, following contention on a lock by this or another
client, immediately notify the waiting process that the lock has been
granted via a wakeup. Without this change, the client rpc.lockd will
not wakeup the waiting process until it next re-polls the lock (sometime
in the next ten seconds), which can lead to marked latency across all
potential lockers, as the lock is held by the client for the duration.

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.
