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.

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

mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

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.
