spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

bthidd(8): Add internal support for user-friendly name of remote devices.

Extend bthidd.conf format to store name of remote Bluetooth HID devices and
implement querying of this information with bthidcontrol(8) "Query" command.

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.

bthidd(8): Add support for vendor_id, product_id and version.

Extend bthidd.conf format to store vendor and product IDs of remote
Bluetooth HID devices to make possible implementation of device
specific quirks inside bthidd(8).
Add support for querying of this information from device's SDP records
with bthidcontrol(8) "Query" command.

Check l2cap socket initialisation and define L2CAP_SOCKET_CHECKED
This will fix build.

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

Do not request SDP attributes using ranges.
Apparently some devices do not like it.

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.

- Fix attribute id of HIDBatteryPower
- Fix two typos in comments

Start committing Bluetooth HID (Human Interface Device) support.
Note: bthidd(8) is still not complete. Need to commit kernel
support (a-la Linux /dev/input) to feed HID events into kernel.
Also need to write bthidd(8) and bthidd.conf(5) man pages.
