include: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Remove $FreeBSD$: one-line .h pattern

Remove /^\s*\*+\s*\$FreeBSD\$.*$\n/

Indent protection and some other oops from the prvious commits.

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.

Allow certain headers to be included more easily.

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.

Remove clause 3 from Berkeley copyrights. Add a few $FreeBSD$'s.

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

RFC2349 (http://www.hypermail.org/rfcs/rfc2349.html) adds support
for negotiation of timeout and file size to the tftp protocol. This
is required by some firmware like EFI boot managers (at least on
HP i2000 Itanium servers) in order to boot an image using tftp. The
attached patch implements the RFC, and in doing so also implements
RFC2347; a generic tftp option extension.

style(9) the structure definitions.

Declare the various 2-byte values in TFTP as being `unsigned short'.
RFC 1350 isn't very explicit about this, but the use of signed
integers doesn't seem to make sense.

Should be in 2.2.5, but is probably too late to be verified completely.
