We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

The new RtpHeaderExtension handling works better with variable length
header extensions, and the new RtpStreamId implementation takes
advantage of it. This is useful to us because we'll be able to add
MID support using the same mechanism.

This enables apm logging by setting the apm_debug_dump variable in gyp.mozbuild.
Prior to this change, some files were including apm_data_dumper.h with logging
enabled and some were not.
This also removes the AEC* C interface and calls into webrtc::Trace directly.
Whatever historical reasons for having a C interface into these calls no
longer seems to apply. In addition reserving a buffer for the base file name
and then ensuring it was null terminated caused an ASAN "stack-buffer-overflow"
while testing. This was because it was not handling an empty base file
name properly. This would not normally happen if AEC logging was enabled through
about:webrtc, but it still seems safer to use std::string.

Do not only rely on the dimensions retrieved via FrameSizeChange. Both the webrtc::VideoFrameBuffer object and layers::Image know about their dimensions.
We still need to keep the FrameSizeChange mechanism so that the attached media element know about its size before a frame is ready to be displayed.
We will revisit this problem later.
Additionally, don't assume that the frame's stride is the same as the frame's width. It may be true with the software decoders currently used, but it's not the norm.

We detect when a PSSH is contained in a MOOF and stash them in the
mp4_demmuxer::Moof object. When the mp4_demuxer::SampleIterator returns a
sample, we check whether it's the first sample from its MOOF, and if so, we
attach any PSSH boxes from that MOOF to the sample. The TrackBuffersManager
checks samples upon demux, to see whether they have any EME init data attached,
and if so dispatches thoses to the HTMLMediaElement in 'encrypted' events.

This removes the disabled TestDummyVideoWithTransport. It was disabled because
it was too flaky to run in automation. It is now broken locally as well due to
threading changes. Given that we can test whether the VideoConduit sends video
well enough in mochitests, I don't see any reason to invest time in fixing it
here, given that it is unlikely to work well in automation anyway.
This also rewrites the MaxFs tests to avoid sending a frame as that results in
a shutdown hang when run in automation.
I have checked that the TestDummyAudioWithTransport continues to work locally,
but I've left it disabled.

Both of these libraries call into libm for various reasons, but by
linking with the C++ compiler on most platforms, they never had to
declare their dependency on libm. Future changes will make these
libraries link with the C compiler, which won't automatically link with
libm, so we need to make the dependency explicit prior to that change.
We can avoid the symbol visibility problem by putting
sanitizer/asan_interface.h in the config/system-headers.

The MoofParser's used by the MP4Demuxer, can grow very large as it keeps adding new tables and is never reset.
Once we have demuxed all data present in the MP4 media segment, we no longer require the samples table for that media segment and we can drop it from the index.
Unfortunately. some websites (in particular some using live video) use media segments containing a single sample in order to (incorrectly) reduce latency. While this is a very bad approach from a performance perspective it does happen in the wild.

This refactor is for exposing necessary symbols of libpng for freetype2 in a

exposed only on Android. And whether these symbols are exposed solely depends
on the target platform checking. A better way to decide whether or not to
expose these symbols would be checking the dependency of freetype2 directly.
When I added this check during the modifications for Bug 1345511 (Move
nICEr stun local address discovery to an IPC call to enable future
sandbox restrictions on content process) I originally thought this was

time the following method(s) is called:
PeerConnectionMedia::EnsureTransports() ->
GatherIfReady() ->
EnsureIceGathering_s()
