The side effect of not filtering on V4L2_CAP_VIDEO_CAPTURE is that every device
is enumerated twice. Because we look up devices by name, and the device that
supports V4L2_CAP_VIDEO_CAPTURE seems to always appear first in /dev/video,
this does not seem to end up with us ever choosing an inappropriate device. We
might get away with just filtering device names from the list, but if the order
of devices ever changed in /dev/video there could be problems.

In this bug we're moving away from monolithic JNI headers to class-specific
headers so that we don't have to rebuild the world every time we make a change
to a JNI interface.

The current code will only set the TranmissionOffset extension if
capture_time_ms is > 0, but when adjusting timestamps for rtx packets, it is
adjusted without first checking to see if it is valid, which will cause invalid
values of capture_time_ms to be written to TranmissionOffset, leading to assertion
failures.
This bug is still present on tip of libwebrtc, so we'll also need to prepare a
patch for upstream.

This imports a few fixes from tip of libwebrtc, which now supports mid, rid
and rrid. The rtx packet is now allocated as max_packet_size_, which is
necessary to have enough capacity for the rrid. It takes the
CopyHeaderAndExtensionsToRtxPacket function from upstream, which omits
copying extensions that should not be copied over, such as rid. It is necessary
to make AllocateExtension and FindExtension public in order for this
function to work.
It then copies the rid from the source packet over to rrid in the rtx packet.
Upstream has code for this as well, but taking it would require more
extensive changes to our copy of libwebrtc. We can drop these local
modifications with the next update.

In order for the SendSideCongestionController to work properly, it needs the
timestamp at which the packets were sent. This is set by calling
Call::OnSentPacket when a packet is sent. Without the sent timestamp, it drops
the estimated available bandwidth so low that only one simulcast stream will
be allocated any bandwidth.

Upstream has removed the mode used when use_desktop_relative_cursor_position_
is set to false as well as the associated override of OnMouseCursorPosition,
so the next time we update libwebrtc, this is the behaviour we will have.
Enabling it now fixes cursor display on Linux, which at the moment only works
for some windows.

I think inner_window_ was added to handle the fact that window_ may not be
the same as child_window which could throw off the coordinates. Since we made
these modifications, upstream has added the XTranslateCoordinates call that
handles this case, so our local modifications are no longer necessary.

This requires --build-peers-said-large-imports-were-ok since
third_party/rust/mp4parse/src/lib.rs is 113KB. This code is just moving from
media/mp4parse-rust to third_party/rust, so it's not really adding to net code
size.

With rtx enabled, we can't just switch ssrcs when we receive a packet with an
unrecognized ssrc. This changes the ReceiveRTPPacket call to take the entire
rtp header, and then examines the payload type. If the payload type is
associated with rtx or ulpfec, the ssrc will not be changed. This is what is
done by the libwebrtc unsignaled ssrc change code, so this behaviour should
match what Chrome does.

This changes the constructor to not take any parameters for consistency
with how the other parameters are handled. It also fixes serialization, the
current code will output an ascii character rather than the numeric value.
