Caps may change the framerate used and the frame counting approach for
timestamps, needs to account for this by taking a snapshot of the current frames
and running time to add to all subsequent produced frames. Code is mostly taken
from videotestsrc.

The download element relied on a fuzzy translation from GStreamer format to a
DRM fourcc, and then all supported modifiers for that fourcc. Since !9306 this
was fixed to only enumerate that way when direct import is used.
Flag direct upload to the transform caps helper, so that we now enumerate all
non-external formats again.

When using direct DMABuf upload, supported DRM formats and modifiers
pairs should be translated to RGBA. Instead of overwriting the translation
to RGBA, which may endup having nothing to override, we introduce a new
flag for the transform helper, so it can do direct translation.
This fixes a regression introduced by !9306, and fixes more negotiations
issues.
Fixes#4525

Some WebRTC implementations such as Pion are unhappy if the
profile-level-id isn't returned with a compatible profile as the
RFC requires. Let's try to reform it
In practice, the correct way to do this would be to not use caps
intersection, but to instead implement the correct RFC compliant
SDP O/A negotiation of formats.

When doing direct dmabuf upload, we rely on the GL stack for doing the color
transformation. The caps we transform from GL to DMABuf are always with a format
of RGBA. Instead of listing all GstVideoFormat and translating them back into
DRM formats, simply list all supported DRM format for the context.
This enable rendering DRM formats that don't have an shader based emulation
implemented such as NV15.

The transformation was fuzzy, adding random modifiers to the list. Use the newly
introduce helpers from 1.26 to precisely convert GStreamer formats to a DRM
fourcc and modifier pair and vice-versa.
This fixes support for formats that have a GstVideoFormat value and requires a
modifier.

Prevent race condition where gst_play_sink_do_reconfigure() could be called
from a pad probe while stream synchronizer pads are being released during
GST_STATE_CHANGE_PAUSED_TO_READY transition.
The race occurred when:
1. State change starts releasing stream synchronizer pads
2. Pads are unblocked earlier in the state change, allowing events to flow
3. A streaming thread triggers sinkpad_blocked_cb -> gst_play_sink_do_reconfigure
4. Reconfiguration tries to use already-released pad pointers
5. New pad creation fails with assertion in gst_pad_iterate_internal_links
The fix adds GST_PLAY_SINK_LOCK around the pad cleanup to ensure atomic
cleanup and prevent concurrent access during state transitions.

A user-supplied window handle (external_view) becomes the superView
of internal_view, which is closed with [view removeFromSuperview].
This fails silently if external_view = NULL (no handle supplied).
Call [win_internal_id close] in this case. Fixes#4432.

The copy of the exact same stream-start event prevents the multiqueue's sink
event function from being called because it is already stored on both pads at
link time
The text streams are no longer considered sparse by the multiqueue, so
interleave calculation is broken and makes us consume a lot of ram and we can
end up killed by the kernel because of this
