b55dfb5313 Add feature options for almost all plugins
The only plugins remaining are those that haven't been ported to Meson
yet, and msdk. Also, the tests are still automagic.

a9b40eebc0 decklink: keep the internal time we send to decklink always increasing
Otherwise decklink seems to hold onto the latest frame and may cause a
flash in the output if the played sequence has a framerate less than the
video output.

Scenario is play for N seconds, pause, flushing seek to some other position,
play again.  Each of the play sequences would normally start at 0 with
the decklink time.  As a result, the latest frame from the previous sequence
is kept alive waiting for it's timestamp to pass before either dropping
(if a subsequent frame in the new sequence overrides it) or displayed
causing the out of place frame to be displayed.

This is also supported by the debug logs from the decklink video sink
element where a ScheduledFrameCompleted() callback would not occur for
the frame until the above had happened.

It was timing related as to whether the frame was displayed based
on the decklink refresh cycle (which seems to be 16ms here),
when the frame was scheduled by the sink and the difference between
the 'time since vblank' of the two play requests (and thus start times
of scheduled playback).

31aafdbea5 decklink: Fix crash with closed-captions signal and 10-bit input
Only free the parser if there is one. If the format hadn't changed but
had always been 10-bit, there might genuinely be no parser.

beab2ee4dc decklink: fix initialization fails in windows binary
There is no log of gst_decklink_com_thread () which initializes COM.
The initialization part is not valid with #ifdef MSC_VER.
Windows binaries are built with gcc.
As with other codes, it was avoidable by setting it to G_OS_WIN32
instead of MSC_VER.

9bb905620c decklink: don't limit number of devices to 16
There is no fixed limitation for the number of devices on the
decklink API side according to BlackMagic. Many PC motherboards
are able support 6 decklink cards each with up to 8 inputs so
a limit of 16 might well be too low.

b5ff71fc3c decklinkaudiosrc: Extrapolate stream/hw reference timestamps when video frame is missing
Sometimes we might get an audio packet without a corresponding video
frame. In these cases, the stream and hardware reference timestamps
would be missing, because they're called on the video frame. Instead of
potentially breaking stuff downstream that might depend on these, we now
extrapolate them.

a3a7d2e0ff decklink: Detect gaps on incoming stream times, issue warnings
When we receive a video or audio buffer, we calculate the next stream
time based on the current stream time + buffer duration. If the next
buffer's stream time is after that, we issue a warning.

This happens because the stream time incoming from Decklink should be
really constant and without gaps. If there is a gap, it means that
something went wrong, e.g. the internal buffer pool is empty (too many
buffers queued up downstream).

Not only if the video sink is set to PLAYING so far. Also give more

86888d9918 decklinkaudiosink: Re-implement around GstBaseSink instead of GstAudioBaseSink
The Decklink and GstAudioBaseSink APIs don't fit very well together,
which causes various problems due to inaccuracies in the clock
calculations and the actual ringbuffer and GStreamer's copy getting of
sync.

Problems are audio drop-outs and A/V sync getting wrong after
pausing/seeking.

5ab660c4e2 decklink: Ignore some driver-set timecode flags
The "fields" flag is ignored because currently GStreamer doesn't support
having only top or only bottom fields inside a frame. The "drop frame"
flag is ignored because some occurrences have been spotted where it
wasn't set while it should have been. In practice, when we have 29.97 or
59.94 FPS, it's always drop-frame.

ca8c63080f decklink: Fix format specifier warnings in logging v2
HRESULT is unsigned long on Windows, but the Decklink headers define
it to 'int' on Linux. Confusingly, the defines that talk about the
possible return values for it use long constants. The easy fix would
be to change the linux/LinuxCOM.h header, but that's copied from the
decklink SDK.

Change the logging to always upcast to unsigned long while printing
HRESULT for consistency across platforms.
