Add a workaround needed to fix a bug of Arasan Host Controller where it may
lose the contents of consecutive writes (that happens within two SD card
clock cycles).
This fixes the causes of instability during the SD card detection and
identification on Raspberry Pi (which happens at 400 kHz and so was much
more vulnerable to this issue).
Remove the previous workaround which clearly can't provide the same effect.

Add a driver for the TI watchdog.
The TI watchdog timer is present on BeagleBone's. Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled. We need to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog. This
is also a reflection of the watchdog(9) API.
In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.

fwsectors and fwheads used to be somehwat arbitrary. However, they are
used to align partitions in gpart. We also try to align partitions by
stripe size when creating new media. Align these two concepts by
making fwsectors the same as the stripe size. Select a sensible number
of heads so we wind up with about 20 cylinders. This number was
selected to keep the rounding effects to a few percent while keeping
the number of cylinder groups low.
Sadly, it is not possible to make these numbers match the numbers used
by SD card readers. There apperas to be much variation between brands
so there's no one universal number. These numbers are also not aligned
to the stripe size, so some performance problems may still be present
when SD cards are created this way.
Also, these numbers will differ from the far less common SD to ATA
adapters, which present a different, but more uniform, set of numbers
that also happened to match the old defaults.
Nothing should change for current users. Any suboptimal performance
caused by misalignment will still be there. gpart will honor the
partitions that aren't on proper boudnaries, but editing the partition
tables may result in different alignments being used than before when
editing things natively.
Ideally, there'd be some way to override these values in the disk
subsystem by the user for the USB adapter use case where all "native"
notions of geometry disappear. This does not implement that.

Prevent ZFS leaking pool free space
When processing async destroys ZFS would leak space every txg timeout
(5 seconds by default), if no writes occurred, until the pool is totally
full. At this point it would be unfixable without a pool recreation.
In addition if the machine was rebooted with the pool in this situation
would fail to import on boot, hanging indefinitely, as the import process
requires the ability to write data to the pool. Any attempts to query the
pool status during the hung import would not return as the import holds
the pool lock.
The only way to import such a pool would be to specify -o readonly=on
to the zpool import.
zdb -bb <pool> can be used to check for "deferred free" size which is where
this lost space will be counted.

When vnode bypass cannot be performed on the cdev file descriptor for

restores the special handling for terminals by calling the deadfs VOP,
instead of always returning ENXIO for destroyed devices or revoked

pointers to the functions, to instead of VOP_PANIC.
