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/

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.

ndbm.h: Add a comment pointing out our non-compliance with POSIX.

Changing it to full conformance breaks the ABI.

Fix prototype of dbm_open().

The last argument of dbm_open() should be a mode_t according to POSIX;
not an int.

Let dbm's datum::dptr use the right type.

According to POSIX, it should use void *, not char *. Unfortunately, the
dsize field also has the wrong type. It should be size_t. I'm not going
to change that, as that will break the ABI.

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 the Berkeley clause 3's.
Add a few $FreeBSD$

Namespace: dbm_forder() and dbm_dirfno() are BSD extensions.

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

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