232bc14718 mtx: reduce lock accesses
Instead of spuriously re-reading the lock value, read it once.

This change also has a side effect of fixing a performance bug:
on failed _mtx_obtain_lock, it was possible that re-read would find
the lock is unowned, but in this case the primitive would make a trip
through turnstile code.

This is diff reduction to a variant which uses atomic_fcmpset.

bb34e01cc2 Add a page queue for holding dirty anonymous unswappable pages.
On systems without a configured swap device, an attempt to launder pages
from a swap object will always fail and result in the page being
reactivated. This means that the page daemon will continuously scan pages
that can never be evicted. With this change, anonymous pages are instead
moved to PQ_UNSWAPPABLE after a failed laundering attempt when no swap
devices are configured. PQ_UNSWAPPABLE is not scanned unless a swap device
is configured, so unreferenced unswappable pages are excluded from the page
daemon's workload.

a9c1591389 Addition of clang nullability qualifiers.
Add two new qualifiers for use by the static checkers:

_Nonnull
The _Nonnull nullability qualifier indicates that null is not a meaningful
value for a value of the _Nonnull pointer type.

_Nullable
The _Nullable nullability qualifier indicates that a value of the
_Nullable pointer type can be null.

These were introduced in Clang 3.7. For more information, see:
http://clang.llvm.org/docs/AttributeReference.html#nonnull

We add these now without using them so that the GCC ports have time to
pick up the header change.

Apparently the libstand dosfs optimization is a bit too optimistic
and did introduce possible memory corruption.

This patch is backing out the bad part and since this results in
dosfs reading full blocks now, we can also remove extra offset argument
from dv_strategy callback.

The analysis of the issue and the backout patch is provided by Mikhail Kupchik.

36c6c3bf8e boot2 will deadlock if extended keys are used on text input
The boot2 family of bootblocks (zfsboot/gptzfsboot) are using separate
implementation if keyboard reading code, which has deadlock case when
extended key (arrows etc) are pressed.

The problem is about avoiding the noise from some systems, generating
false key events with scan code 1 and ascii code 00, so the code
does attempt to filter such cases out. Unfortunately the extended keys
also set ascii 0, and therefore the pressed key event is ignored and
the keypress is never read, resulting in infinite loop.

This update is moving the check to keyhit() function and is allowing
the rest of the code to process the extended keys.

* Change the worker lock to a normal mutex rather than a spin lock.
  Drivers shouldn't be doing netmap work from the fast interrupt
  handlers, so it's not required to be a spinlock.
