Basically the msg ring interrupt was being re-enabled
inside a spinlock as the thread set it self up for rescheduling.
This won't work since inside the re-enable is another

stopped and debugger may modify or drop the signal. After the changes to
keep process-targeted signals on the process sigqueue, another thread
may note the old signal on the queue and act before the thread removes
changed or dropped signal from the process queue. Since process is
traced, it usually gets stopped. Or, if the same signal is delivered
while process was stopped, the thread may erronously remove it,
intending to remove the original signal.
Remove the signal from the queue before notifying the debugger. Restore
the siginfo to the head of sigqueue when signal is allowed to be
delivered to the debugee, using newly introduced KSI_HEAD ksiginfo_t
flag. This preserves required order of delivery. Always restore the
unchanged signal on the curthread sigqueue, not to the process queue,
since the thread is about to get it anyway, because sigmask cannot be
changed.
Handle failure of reinserting the siginfo into the queue by falling
back to sq_kill method, calling sigqueue_add with NULL ksi.
If debugger changed the signal to be delivered, use sigqueue_add()
with NULL ksi instead of only setting sq_signals bit.

Add video clipping support but with the caveats below.
Background info:
Video clipping allows the user to provide either a series of clip rectangles
or a clip bitmap to the driver and have the driver mask the video according
to the clipping specs provided.
Adding support for clipping to the FreeBSD Linux emulator is problematic
because it seems that this feature is not supported by many drivers and
therefore it is ignored by many applications. Unfortunately, when not
using it, rather than passing in a null clipping list, some apps leave the
clipping fields uninitialized, casuing random values to be passed in. In
the case where the driver does not use the clipping info, this is not a
problem (although it is bad form). But the Linux emulator does not know
which drivers will use this and which won't, so the Linux emulator must
try to handle this clip list, and deal gracefully with cases where the
values seem to be uninitialized.
Video clipping info is passed in using the VIDIOCSWIN ioctl in two fields
in the video_window structure: the integer clipcount and the pointer clips.
How the linuxulator handles this from this commit on:
* if (clipcount == VIDEO_CLIP_BITMAP)
The clips variable is a void * pointer to a 128*625 byte
(1024*625 bit) memory area containing a bitmap of the clipping area.
The pointer in the video_window structure is copied, but no
video_clip structures are copied.
* if (clipcount > 0 && clipcount <= 16384)
The clips variable is pointer to a list of video_clip structures. Up
to clipcount structures are copied and passed to the driver.
The upper limit of 16384 was imposed here so that user code that does
not properly initialize clipcount falls through below and no attempt
is made to copy an uninitialized list. This value was found by
examining Linux drivers that support the clip list.
* else
The clipcount is either negative (but not VIDEO_CLIP_BITMAP), zero or
positive (> 16384).
All these cases are treated as invalid data. Both the clipcount field
and clips pointer are forced to zero/NULL and passed to the driver.
It should be noted that, at the time of developing this V4L emulator code,
the pwc(4) V4L driver does not support clipping.
