spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

Be bug compatible with other operating systems by allowing non-sequential
interface numbering for USB descriptors in userspace. Else certain USB
control requests using the interface number, won't be recognized by the
USB firmware.

Refer to section 9.2.3 in the USB 2.0 specification:
Interfaces are numbered from zero to one less than the number of concurrent interfaces
supported by the configuration.

lib: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.

lib: minor spelling fixes in comments.

No functional change.

libusb: Fix minor cast-qual warning.

Fix a warning triggered by the gcc + FORTIFY_SOURCE patches:

In function 'libusb20_parse_config_desc': lib/libusb/libusb20_desc.c:141:
warning: passing argument 1 of 'memcpy' discards qualifiers from pointer
target type

Add definition of some USB 3.0 descriptors to libusb 1.0 and libusb 2.0.
Some header file parts of this patch were taken from a patch submitted
by Maya Erez <merez@codeaurora.org> to the LibUSB developers list.

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.

Resort includes to match style(9) a bit more. No functional change
is expected after this commit.
