spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

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.

Simplify kvm symbol resolution and error handling. The symbol table
nl_symbols will eventually be organized into several modules depending
on MK_* variables.

Convert netstat to use libxo.

While printing out the WSID and CPU ID only the first time it appears for
each workstream, rather than on every protocol, is prettier, it makes
machine-parsing of netstat -Q output a lot harder. Repeat the information
and hope that the user forgives us slightly dense formatting.

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.

Prefer vocabulary of 'Current' and 'Limit' to 'Value' and 'Maximum' in

Teach netstat -Q to work with -N and -M by adding libkvm versions of data
query routines. This code is necessarily more fragile in the presence of
kernel changes than querying the kernel via sysctl (the default), but
useful when investigating crashes or live kernel state via firewire.

Currently supports only reporting on live systems via sysctl, kmem support
needs to be edded.
