c363b16c63 sys: Remove DEV_RANDOM device option
Remove 'device random' from kernel configurations that reference it (most).
Replace perhaps mistaken 'nodevice random' in two MIPS configs with 'options
RANDOM_LOADABLE' instead.  Document removal in UPDATING; update NOTES and
random.4.

251a32b5b2 tun/tap: merge and rename to tuntap
tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).

This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp

[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).

ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.

(MFC commentary)

This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.

I have no plans to do this MFC as of now.

INTRNG is required on all armv6 and armv7 systems, so make it
standard.

638a5afda9 Move device statements out of std.imx* and into kernel config files.
In the armv4/5 world device statements in these files were common, but in
the v6/7 world, other socs don't put device statements into those files, so
this just brings imx5 and imx6 into line with the current conventions.

f82eace5b3 Build modules specific to imx5/imx6 only when building those kernels.
This adds sys/modules/imx with a SUBDIR makefile to make the whole
collection of modules that are specific to these SoCs.  Initially, that
"whole collection" consists of the if_ffec and imx_i2c drivers.

The if_ffec driver is referenced in its existing home in ../ffec rather
than moving it into the imx directory, because it's used by powerpc too,
but it is no longer built for all armv6/7 systems.

The imx_i2c driver is newly added as a module.

094fc1ed0f Tag all armv7 kernels as such in their machine config line.
Transition all boards that support arm cortex CPUs to armv7. This
leaves two armv6 kernels in the tree. RPI-B, which uses the BCM2835
which has a ARM1176 core, and VERSATILEPB, which is a qemu board setup
around the time RPI-B went in. Copy std.armv6 to std.armv7, even
though that duplicates a lot of stuff. More work needs to be done to
sort out the duplication.

8ef1f44afe Remove old COMPAT_FREEBSD options from the ARM kernel configs. We replaced
the ABI in 10.0, and have removed support for the old ABI in 11. As such
any of these options to provide compatibility prior to 10 are unneeded.

65c3de4e62 Create std.arm and std.armv6 config files and include the right one from
each of the existing kernel configs.  This gives a place to put config
that applies to the entire arch.

Add the ARM_NEW_PMAP option to std.armv6.  This is working well in early
testing and it's time for wide exposure, but it's still nice to be able
to fall back to the old implementation for testing when a problem comes
along.  Eventually the option and the old implementation will go away.

The opportunity now exists to move a whole lot of boilerplate from all the
arm kernel config files into std.arm*, but that's a commit for another day.

603eaf792b Renove faith(4) and faithd(8) from base. It looks like industry
have chosen different (and more traditional) stateless/statuful
NAT64 as translation mechanism. Last non-trivial commits to both
faith(4) and faithd(8) happened more than 12 years ago, so I assume
it is time to drop RFC3142 in FreeBSD.
