uvideo: increase isochronous transfer depth for throughput
Increase NFRAMES_MAX from 40 to 128 and IXFERS from 3 to 5 to keep
more packets in flight on the USB bus. This brings throughput from
~13.5 MB/s to ~21 MB/s (for comparison on the same camera webcamd
provided ~20MB/s.
The linux driver also uses 5 IXFERS (but only 32 NFRAMES_MAX)

uvideo: add Camera Terminal controls
Implement UVC Camera Terminal (CT) controls per UVC 1.5 specification
Table A-12. This adds support for camera-specific controls that are
separate from the Processing Unit controls already supported.

uvideo: add kqueue support
Add EVFILT_READ kqueue filter so applications using kqueue/kevent
can efficiently wait for video frames instead of polling.

uvideo: import uvideo(4) driver from OpenBSD
Port the uvideo(4) driver from OpenBSD. This provides
native USB Video Class (UVC) support for webcams and video capture
devices.
The main changes are adaptation for:
- USB transfer callback model
- isoc data extraction via usbd_copy_out(),
- V4L2 struct alignment for ABI compatibility with v4l_compat.
Note that this implementation can coexist with webcamd.

tools/test/stress2/misc/msdos12.sh: fix permission issue
This test runs with rights of an un-privileged user writing to a file
system only writable by the owner. Since no UID was provided in the
mount command, the owner of the file system was "root", and thus
writing was not allowed for $testuser. Fix this issue by mounting
with "-u $testuser".

tools/test/stress2/misc/all.debug.inc: skip undefined variables
On my ZFS based systems, no allocations occur with tags "newblk" or

tools/test/stress2/misc: Add msdosfs tests for surrogate pairs
Test msdos22.sh creates 1000 files with long random names consisting
of only ASCII characters. The mount is performed without -L option,
therefore no use of iconv to convert between character sets.
Test msdos23.sh mixes some non-ASCII characters into the file names.
The file system is therefore mounted with -L C.UTF-8 to include tests
of the conversions between UTF-8 and UTF-16.
Test msdos24.sh adds emojis to the names to test the (not yet
committed) support of UTF-16 surrogate pairs in filenames.

fs/msdosfs: add support for file namws with surrogate pairs
Long file names are using UTF-16 symbols to represent international or
special characters. The implementation in FreeBSD did not support the
"Supplementary Private Use Area-B" (PUA-B), which requires a surrogate
pair to be represented in UTF-16 (Unicode code points beyond U+FFFF).
The PUA-B is used to represent emoji characters, which are supported
in file names on other common operating systems. The motivation for
this change was that removable media written on another system were
only partially readable on FreeBSD, since they contained emojis in
file names.
A test script that verifies correct operations on files names with
emojis has been added to the tools/test/stress2/misc directory under
the name msdos24.sh.

auditd: Fix signal handling
Rewrite the main loop to use ppoll() instead of just blocking on read,
blocking the signals we care about when we aren't polling.
I didn't bother replacing alarm() with setitimer(); the alarm code
is dead anyway since there is no way for max_idletime to acquire a
non-zero value.
While here, avoid leaking the pid file and trigger descriptors to the
log child.
