spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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 evdev protocol support for bluetooth keyboards and mouses

User-visible changes:

"-u" is added to to list of command line options supported by bthidd.
Use it to enable evdev support. uinput and evdev modules should be
kld-loaded or compiled into the kernel in that case.

bthidd_evdev_support rc.conf variable is added to control enabling of
evdev support in bthidd startup script. Possible values are: "YES", "NO",
"AUTO"(default). Setting bthidd_evdev_support to "AUTO" inserts "-u" option
if kernel is compiled with EVDEV_SUPPORT option enabled.

Support for consumer HID usage page keyboard events is implemented. Most of
them are available only through evdev protocol.

kern.evdev.rcpt_mask sysctl is checked, so "sysctl kern.evdev.rcpt_mask=12"
should be executed if EVDEV_SUPPORT is compiled into kernel.

It is recommended to regenerate bthidd.conf entries with bthidcontrol(8)
"Query" command to set user-friendly names of bluetooth devices.

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.

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

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.

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

Temporarily put ugly workaround in place to make sparc64 build happy.
panther is down at the moment, so better fix will follow later.

Update bthidd(8) code and hook it up to the build.
bthidd(8) now was integrated with vkbd(4) and supports
multiple keyboards via vkbd(4)/kbdmux(4).

The code was tested with Apple Bluetooth keyboard and
SE k700i cell phone (remote control feature).
