62b6224e37 wasapi: Increase thread priority to reduce glitches
This is particularly important when running in exclusive mode because
any delays will immediately cause glitching.

The MinGW version in Cerbero is too old, so we can only enable this when
building with MSVC or when people build GStreamer for MSYS2 or other
MinGW-based distributions.

To force-enable this code when building with MinGW, build with
CFLAGS="-DGST_FORCE_WIN_AVRT -lavrt".

6ecbb7556a wasapi: Allow opening devices in exclusive mode
This provides much lower latency compared to opening in shared mode,
but it also means that the device cannot be opened by any other
application. The advantage is that the achievable latency is much
lower.

In shared mode, WASAPI's engine period is 10ms, and so that is the
lowest latency achievable.

In exclusive mode, the limit is the device period itself, which in my
testing with USB DACs, on-board PCI sound-cards, and HDMI cards is
between 2ms and 3.33ms.

We set our audioringbuffer limits to match the device, so the
achievable sink latency is 6-9ms. Further improvements can be made if
needed.

3f7e29d5b3 Add new 'proxy' element to stream data between pipelines
This keep-it-simple plugin is useful when you want to pipe arbitrary
data to a different pipeline within the same process. Some advantages
over appsink/appsrc, the inter elements, etc:

* Ease of use. Buffers, events, and caps are transmitted as-is without
  copying or serialization.
* Enables zerocopy (especially DMABUF) transparently without any
  special-casing.
* Enables usage with sinks or elements that are unreliable and may
  throw errors and need re-initialization, such as a network sink, a
  USB device sink (v4l2), etc.
* Transmits arbitrary data, not just audio/video/subs
* Can easily implement 1 producer pipeline -> N dynamic consumer
  pipelines within a single process when combined with the `tee`
  element.

All queries, events, buffers, and buffer lists are proxied. State
changes, clocks, and base times for the two pipelines are independent
since the upstream and downstreams continue to be different pipelines.

1894293d63 webrtcbin: an element that handles the transport aspects of webrtc connections
SDP's are generated and consumed according to the W3C PeerConnection API
available from https://www.w3.org/TR/webrtc/

The SDP is either created initially from the connected
sink pads/attached transceivers as in the case of generating an offer or
intersected with the connected sink pads/attached transceivers as in
the case for creating an answer.  In both cases, the rtp payloaded streams
sent by the peer are exposed as separate src pads.

The implementation supports trickle ICE, RTCP muxing, reduced size RTCP.

f6cb16ab8c gdpdepay: don't use allocator if it has custom alloc
gdpdepay element uses the decide_allocation to fetch the downstream
allocator. Nonetheless it is possible that allocate uses a custom
alloc function, which is not usable by gdpdepay, crashing later the
application when the allocater buffer is NULL.

This patch checks for the allocator flags and reset it if the
allocator has a custom alloc function.

538ccb6093 wasapi: Correctly set ringbuffer segsize/segtotal
This will set the actual-latency-time and actual-buffer-time of the sink
and source.

We completely ignore the latency-time/buffer-time values set
on the element because WASAPI is happiest when it is reading/writing at
the default period. Improving this will likely require the use of the
IAudioClient3 interfaces which are not available in MinGW yet.

cedc7d4def codecparser: vp8: Fix range decoder init
According to the vp8 spec, the first partition (size can be derived from
the frame header) should have all compressed header information and we
implemented gst codecparser based on that. But it doesn't seem to be the
case with some of the streams (#792773) and libvpx
works fine because it uses the whole frame size (not the first partition
size) to initialize the bool decoder.

e9aa117200 srtp: Support libsrtp2
For libsrtp 1, add defines that translate the new namespaced identifiers
to the old unnamespaced ones. Also move the code for setting and getting
a stream's ROC into two compat functions that match libsrtp2's API.

It seems that libsrtp2 properly supports changing the ROC without having
to touch the sequence numbers afterwards, given that srtp_set_stream_roc
sets a pending_roc field, so the entire roc_changed dance should not be
needed anymore. The compat functions for libsrtp 1 just contain our
preexisting hacks, however, so it's still needed there.

libsrtp2 has no means of discovering the streams in the session, so to
create the stats structure we need to iterate over our own set of SSRCs.
For this we also need to re-add the previously removed ssrcs_set to the
encoder.
