spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

ar: Avoid overwriting the stdout file stream pointer

This doesn't work with musl, which defines stdout as FILE * const.
Instead, explicitly pass the desired output stream to ar_read_archive().

No functional change intended.

Previously ar and ranlib returned with exit status 0 (success) in the
case of a missing file or other error. Update to use error handling
similar to that added by ELF Tool Chain after that project forked
FreeBSD's ar.

Previously ar would report an error like "ar: fatal: Write error"
without including additional errno information. Change warnings and
errors to include archive_errno() so that the user may have some idea
of the reason for the failure.

usr.bin/ar: use standard 2-Clause FreeBSD license

Many licenses on ar files contained small variations from the standard
FreeBSD license text. To avoid license proliferation switch to the usual
standard 2-clause FreeBSD license for those files where I have obtained
permission from all of the listed copyright holders.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

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.

No functional change intended.

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

Add -D (deterministic) option to ar.
When set, it forces all timestamps and owners to zero and
modes to 0644. Useful for producing libraries that are
bitwise identical across multiple build runs.

Removed ar(1)'s support for compressed archives. This change removes
ar(1)'s dependencies on compressor libraries -lz, -lbz2 and -llzma and
fixes building HEAD on some versions of FreeBSD[78]. Option -j and -z
is now accepted but ignored.

Compressed ar(1) archives are not useful without a ld(1) that can read
them. Also, the current ar(1) compression scheme prevents random
access of archive members and needs to be redesigned anyway.

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.

Add support for option "-M", which is used to operate ar(1) in a
script mode like the MRI(Microtec Research Inc.) "librarian" program.

Originally this option is provided by Binutils ar(1) to ease the
transition for developers who are used to writing "librarian" scripts.

We added this option to BSD ar(1) because:

1. Further improve the compatibility with Binutils ar(1).
2. There are still a few software using this -M option. (at least one
in our ports collection)

Suggested by: rink & erwin

GNU ar did NOT implment option -q as a synonym of -r as the manual
page stated, thus BSD ar(1) option -q, which was implemented based on
the GNU ar manual page, turns out to be incompatible with GNU ar -q.

This change will make BSD ar(1) -q a *REAL* GNU ar -q:

1. It will update symbol table. (same as unfixed version)
2. It will NOT compare new members spcified in the command line args
with existing members, instead, append them directly.
