docs: explicitly declare gir build dependencies

As the path to the gir file is passed to hotdoc.generate_doc() and
not the build target itself, meson doesn't know about the dependency.

In turn, as the CI doesn't build everything before building the
documentation target, some gir files might not exist, for instance
in the case of gst-rtsp-server, causing the output documentation to
be empty.

The error occurred silently because hotdoc accepts wildcards for
*-sources arguments, thus it won't warn about a missing gir file as
it is legitimate for glob matching to resolve to nothing.

opusdec: Try harder to negotiate the upstream channels/rate preferences

gstelement: fix deadlock in gst_element_add_pad() when >=PAUSED

gst_element_add_pad() is supposed to activate the pad if the element
state is >= PAUSED and the pad is not already active.

Unfortunately, before this patch, the activation was performed while the
element lock was still taken, which ended causing a deadlock in
gst_pad_start_task() as it attempted to post `stream-status` message in
the element, which also requires the element lock.

Elements could work around this bug by activating the pad manually
before adding it to the element.

This patch fixes the problem by performing pad activation only after the
element lock has been released.

multiqueue: Fix potential deadlock with parallel release_pad calls

Commit d3a66f9851ea introduced a potential deadlock with two parallel release_pad
calls, where one could release the main multiqueue lock (qlock) while still
holding the reconf_lock and then calling other routines which in some conditions
may try to acquire qlock again. The second release_pad could already acquire the
qlock and then start waiting on reconf_lock, which may never be possible because
because the first one isn't releasing it until it can acquire qlock.

Fix it by holding reconf_lock for the whole durationg of qlock, making this
particular deadlock impossible.

qtmux: For video with N/1001 framerates use N as timescale instead of centiframes

This is recommended by various specifications for such framerates, while
for integer framerates we continue using centiframes to allow for some
more accuracy.

Using N means that no rounding error accumulates, eventually leading to
outputting a packet with a different duration.

Some tools such as MediaInfo determine that a stream is variable
framerate if any packet has a different duration than the others, and
there is no reason I can see for not using the full 4 bytes of
resolution that the mp4 timescale offers.

Example problematic pipeline:

```
videotestsrc num-buffers=5001 ! video/x-raw,framerate=60000/1001,width=320,height=240 ! \
videoconvert ! x264enc bitrate=80000 speed-preset=1 tune=zerolatency ! h264parse ! \
video/x-h264,profile=high-10 ! mp4mux ! filesink location="result2.mp4"
```

This results in a media file that MediaInfo detects as variable
framerate because the 5000th packet has duration 99 instead of 100.

With this patch, the timescale is 60000 and all packets have duration
1001.

cudabasetransform: Update CUDA stream on context update

CUDA stream must be associated with updated CUDA context

va: Delay the VAProcPipelineCaps query after context created.

The VAAPI vaQueryVideoProcPipelineCaps() requires the context as the
parameter. So far, we always pass VA_INVALID_ID and it can succeed.
But the API does not say that and in theory, a valid context is required.
Now the new platform really needs a valid context and so we have to
delay that query until the context is created.

qmlglsrc: Handle HiDPI scaling

When calculating the capture framebuffer size, include

qmlglsrc: Unmap buffer before adding sync meta

Adding a sync meta to a GstBuffer requires that it
be writable. Mapping the buffer with the video frame API
holds an extra ref on the buffer, so unmap before
trying to modify it.

nvdec: Don't use default CUDA stream

NVDEC launches CUDA kernel function (ConvertNV12BLtoNV12 or so)
when CuvidMapVideoFrame() is called. Which seems to be
NVDEC's internal post-processing kernel function, maybe
to convert tiled YUV to linear YUV format or something similar.

A problem if we don't pass CUDA stream to the CuvidMapVideoFrame()
call is that the NVDEC's internel kernel function will use default CUDA stream.
Then lots of the other CUDA API calls will be blocked/serialized.

To avoid the unnecessary blocking, we should pass our own
CUDA stream object to the CuvidMapVideoFrame() call

urisourcebin: Modify check for streams-aware adaptive demuxers

Using the "GstBin" flags to check if an adaptive demuxer is streams-aware isn't
a good idea since it prevents using elements which aren't bins.

Instead we see if a collection was posted by the demuxer by the time a pad is
added.

mpegts: Always clear packetizer on DISCONT push mode

If a discontinuity is detected in push mode, we need to clear the cached section
observations since they might have potentially changed.

This was only done properly when operating with TIME segments (dvb, udp,
adaptive demuxers, ...) but not with BYTE segments (such as with custom app/fd
sources).

We still don't want to flush out the PCR observations, since this might be
needed for seeking in push-based BYTE sources.

qtdemux: Always use `tfdt` if available in BYTE segments

This reverts the decision from
  https://bugzilla.gnome.org/show_bug.cgi?id=754230
where it was decided that we rather play safe and only use the `tfdt` if
it is "significantly different" to the sum of sample durations.

As the specification says

    If the time expressed in the track fragment decode time (‘tfdt’) box
    exceeds the sum of the durations of the samples in the preceding
    movie and movie fragments, then the duration of the last sample
    preceding this track fragment is extended such that the sum now
    equals the time given in this box.

we have to use the `tfdt` in general to allow for it to signal gaps in
the stream.

A muxer producing fragments might not yet know the full duration of the
last sample of a previous fragment if the next fragment starts with a
gap, and knowing the actual start of the next fragment would potentially
require to violate latency requirements.

Additionally, the existence of `tfdt` allows to avoid accumulating
rounding errors from summing up the durations.
