Add support for the Zybo and similar boards to ZEDBOARD kernel.

Ensure that all arm kernel configs contain ALT_BREAK_TO_DEBUGGER and not
BREAK_TO_DEBUGGER if they have a serial console (most do). A burst of
serial line noise (such as unplugging a usb serial adapter) can look like
a break and drop a working system into the debugger. The alt break sequence
(<CR>~^B) works fine on both serial and non-serial consoles.

Use the new gic option on all configs that need it.

Clean up the ARM kernel configs to use 'include<space><tab>"file"'.

Move the first batch of common armv6 options to std.armv6.

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.

In preparation for the next cycle of official ARM images, add ARM_NEW_PMAP
to supported kernels.

This is a temporary solution and should be reverted when ARM_NEW_PMAP is
enabled by default.

Remove MODULES_OVERRIDE="" and WITHOUT_MODULES="ahc" from armv6 configs.

These are left over from long ago when there was no way to load modules
on early armv6 platforms, and when there was a build problem with ahc
that has long since been fixed, and they just keep getting copy-pasted
into new configs.

Remove "New" label from NFSCL/NFSD now that they are the only NFS
client/server. While here, remove duplicate NFSCL from sys/conf/NOTES.

Add SMP support for Zedboard.

In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

Make all the comments '# ' and align to same column. This fixes the
rampently incosnsitent usage which made cut and paste from one file
to another look ugly.

Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture. Move the other contents into each of the individual
config files.

Revert r260440. I didn't realize that most of this change was already
in effect due to r250753. That is sufficient for all SoCs with a 32 byte
cache line size. Systems with 64 byte cache lines will need the option;
that will be done in a separate commit.

Thanks to loos@ for pointing out r250753.

Add option USB_HOST_ALIGN to configs that contain 'device usb'. Setting
this to the cache line size is required to avoid data corruption on armv4
and armv5, and improves performance on armv6, in both cases by avoiding
partial cacheline flushes for USB IO.

All these configs already exist in 10-stable. A few that don't (and
thus can't be MFC'd yet) will be committed separately.

Enable VFP on the Zedboard.

Back out r253779 & r253786.

Decouple yarrow from random(4) device.

* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.

* random(4) device doesn't really depend on rijndael-*. Yarrow, however, does.

* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
random_adaptor is basically an adapter that plugs in to random(4).
random_adaptor can only be plugged in to random(4) very early in bootup.
Unplugging random_adaptor from random(4) is not supported, and is probably a
bad idea anyway, due to potential loss of entropy pools.
We currently have 3 random_adaptors:
+ yarrow
+ rdrand (ivy.c)
+ nehemeiah

* Remove platform dependent logic from probe.c, and move it into
corresponding registration routines of each random_adaptor provider.
probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.

* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload'ed.

* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.
