Remove ChangeLog files from git repository

This information is tracked fully in the git repository, so
no point having the ChangeLog duplicate it, and it interferes
with grepping the repository.

We are going to create the ChangeLogs on the fly when generating
tarballs going forward (with a limited history), since it's still
valuable for tarball consumers to be able to easily see a list of
recent changes.

v4l2src: Fix crash in renegotiation

This regression was introduce by fix for making buffer pool thread safe. When
we renegotiate, the pool will be setup after we set the format. But the code
has been simplified to only get the pool once before, which caused a null
pointer deref.

webrtc: Fix possible use-after-free of GstWebRTCICETransport

Because of the asynchronous resolving of mDNS ICE candidates it is
possible that GstWebRTCICE outlives webrtcbin. This in turn prolongs
the lifetime of the GstWebRTCNiceStream objects via refs in
nice_stream_map. Thus the GstWebRTCICETransport objects held in
GstWebRTCNiceStream may be invalid at the time they are accessed by
the _on_candidate_gathering_done() callback since GstWebRTCNiceStream
doesn't take a reference to them. Doing so would create a circular
reference, so instead this commit introduces weak references to the
transport objects and then we can check if the objects are valid before
accessing them.

vaav1dec: Use gst_va_base_dec_set_output_state().

vavp9dec: Use gst_va_base_dec_set_output_state().

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3480>

va: Add and use common decode negotiate vmethod.

This vmethod can be used by decoders with the same VA decoder reopen logic:
same profile, chroma, width and height.

Also a new public method called gst_va_base_dec_set_output_state() with the
common GStreamer code for setting the output state, which is always called by
the negotiate vmethod.

In order to do this refactoring, new variables in vabasedec have to be populated
by the decoders:

* width and height define the resolution set in VA decoder. In the case of H264
  would be de coded_width and codec_height, or max_width and max_height in AV1.
* output_info is the downstream video info used for negotiation in
  gst_va_base_dec_set_output_state().
* input_state, from codec parent class shall be also held by vabasedec

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3480>

va: Add and use gst_va_base_dec_prepare_output_frame().

This helper will do downstream negotiation and later will

H265 and AV1 decoders don't use this approach since their output
frame allocation is different.

win32ipc: Add WIN32 shared memory videosrc/sink elements

Windows supports various IPC methods but that's completely
different form that of *nix from implementation point of view.
So, instead of adding shared memory functionality to existing
shm plugin, new WIN32 shared memory source/sink elements
are implemented in this commit.

Each videosink (server) and videosrc (client) pair will communicate
using WIN32 named pipe and thus user should configure unique/proper
pipe name to them (e.g., \\.\pipe\MyPipeName).
Once connection is established, videosink will create named shared memory
object per frame and client will be able to consume the object
(i.e., memory mapped file handle) without additional copy operation.

Note that implementations under "protocol" directory are almost
pure C/C++ with WIN32 APIs except for a few defines and debug functions.
So, applications can take only the protocol part so that the application
can send/receive shared-memory object from/to the other end
even if it's not an actual GStreamer element.

rtpsession: Support disabling late adjustment of ntp-64 header ext

Currently in rtp_session_send_rtp(), the existing ntp-64 RTP header

This commit provides the ability to configure whether or not to update

update-ntp64-header-ext boolean property. The property is also exposed

decodebin3: Properly reset when going back to READY

Clear the remaining stream-related fields when going from PAUSED to READY, and
use when disposing.

Fixes various issues when re-using decodebin3/playbin3

decodebin3: Don't output bogus GST_MESSAGE_STREAMS_SELECTED

When `is_selection_done` is called, it checks that all the requested streams are
present in the active stream list ...

... except there could very well be a (about to be removed) stream from the
previous selection present.

Therefore filter the list of streams we add to the message by the streams which
are actually requested.

Fixes issues when switching between different stream types (ex: video-only to
audio-only).

Use the correct SSRC(s) when routing a RTCB FB FIR

Previously we tried to route an incoming RTCP FB FIR to the correct ssrc
using the "media source" component of the RTCP FB message. However,
according to RFC5104 (section 4.3.1.2) the "media source" SHALL be set
to 0. Instead the ssrc(s) in use are propagated via the FCI data. Now
a specific GstForceKeyUnit event is sent for every ssrc.

rtpsource: Track the seqnum for senders

RTP source statistics are tracked for local senders by
treating them as a receiver of their own outbound packets.

Accordingly, track the highest packet seqnum so that the
packets-lost calculation generates a sensible number instead
of always reporting -$number_of_packets_sent

kmssink: Fix compilation without kernel headers

There was a drm/drm_mode.h included added recently, drm/ is usually
referencing the linux kernel header, but we only requires the libdrm
headers to be installed. On top of this, including drm_mode.h is never
needed as its already included by drm.h.

h265parse: Add the missing timestamp when splitting a frame.

When splitting a frame, the gst_buffer_copy_region() does not copy
the timestamp correctly for sub frames when the offset is not 0.
We still need those timestamps for each output sub frame.

rtspsrc: Don't replace 404 errors with "no auth protocol found"

When getting a "404 Not Found" response from the DESCRIBE request, the
source produced a "No supported authentication protocol was found" error
instead of passing on the 404, which was confusing.

Only produce this error message when we're handling a response of "401
Unauthorized" without a compatible WWW-Authenticate header.

The legacy emulation in DRM/KMS drivers badly interact with GStreamer and

vsync (which is handled internally by the emulation) in order to regain the
full framerate.

pad: Fix sticky event ordering for instant-rate-change

The event type for instant-rate-change events was poorly chosen,

different to the value of the event type to fix that up.
