This commit has evolved from the original work to include Capsicum
integration.  As part of that, it only opens the host audio devices once
and leaves them open, instead of opening and closing them on each guest
access.  Thanks to Peter Grehan and Marcelo Araujo for their help in
bringing the work forward and providing some of the final techncial push.

Previously if we had a FONTBOUNDINGBOX or DWIDTH entry that had missing
or invalid values and and failed sscanf, we would proceeded with
partially initialized bounding box / device width variables.

VOP_GETPAGES intentionally tries to read beyond EOF, so fuse_read_biobackend
can't rely on bp->b_resid > 0 indicating a short read.  And adjusting
bp->b_count after a short read seems to cause some sort of resource leak.
Instead, store the shortfall in the bp->b_fsprivate1 field.

Resolve the incorrect use of srcdir and builddir references for
various files in the build system.  These have crept in over time
and went unnoticed because when building in the top level directory
srcdir and builddir are identical.

With this change it's again possible to build in a subdirectory.

    $ mkdir obj
    $ cd obj
    $ ../configure
    $ make

had been done years ago.  I did.  All this time we've only compiled a LINT
kernel for TARGET_ARCH=arm.  Now separate LINT-V5 and LINT-V7 configs are
generated and built.

There are two new files in arm/conf, NOTES.armv5 and NOTES.armv7, containing
some of what used to be in the arm NOTES file.  That file now contains only
the bits that are common to v5 and v7.

The makeLINT.mk file now creates the LINT-V5 and LINT-V7 files by concatening
sys/conf/NOTES, arm/conf/NOTES, and arm/conf/NOTES.armv{5,7} in that order.

Port the code to block on turnstile instead of yielding, to lock-less
delayed invalidation. The yield might cause tight loop due to priority
inversion.

Since it is impossible to avoid race between block and wake-up, arm
1-tick callout to wakeup when thread blocks itself.

into existing files for sugid processes.

Despite using real user id pronounces the intent, it actually breaks
suid coredumps, while not making any difference for non-sugid
processes.  The reason for the breakage is that non-existent core file
is created with the effective uid (unless weird hacks like SUIDDIR are
configured).

Then, if user enabled kern.sugid_coredump, core dumping should not
overwrite core files owned by effective uid, but we cannot pretend to
use real uid for dumping.

perform a TLB invalidation.  A barrier suffices.  (See r343876.)

Add a comment to pmap_enter_quick_locked() in order to highlight the
fact that it does not replace valid mappings.

Correct a typo in one of pmap_enter()'s comments.
