396aa55958 ajasrc: Improve clock handling
Provide a clock from the source that is a monotonic system clock with
the rate corrected based on the measured and ideal capture rate of the
frames.

If this clock is selected as pipeline clock, then provide perfect
timestamps to downstream.

Otherwise, if the pipeline clock is the monotonic system clock, use the
internal clock for converting back to the monotonic system clock.

Otherwise, use the monotonic system clock time calculated in the above
case and convert that to the pipeline clock.

In all cases this will give a smoother time than the previous code,
which simply took the difference between the driver provided capture
time and the current real-time clock time, and applied that to the
current pipeline clock time.

86e3009448 ajasrc: Move frame drop detection after the frame transfer
Otherwise there's a small window between querying the state and doing
the transfer in which a frame could be dropped, and we would then output
the frame right after the dropped one as if it was the dropped frame.

d86a6715e1 aja: Replace global semaphore with per-device flock()
The global semaphore was never closed/unlinked, causing permission
denied issue if the device is later used by another user. Properly
removing the semaphore when stopping the pipeline would still leave it
open in case of a crash.

With a GStreamer specific name, it was also not preventing other apps to access
the device concurrently.

Finally, if the system has multiple cards, the lock should be per card
and not global (to be confirmed).

Fixes: #3283.

This shouldn't have been left at the top-level but was forgotten to be
moved when merging the repository histories.
