317a1f09ed Use std::make_unique instead of absl::make_unique.
WebRTC is now using C++14 so there is no need to use the Abseil version
of std::make_unique.

This CL has been created with the following steps:

git grep -l absl::make_unique | sort | uniq > /tmp/make_unique.txt
git grep -l absl::WrapUnique | sort | uniq > /tmp/wrap_unique.txt
git grep -l "#include <memory>" | sort | uniq > /tmp/memory.txt

diff --new-line-format="" --unchanged-line-format="" \
  /tmp/make_unique.txt /tmp/wrap_unique.txt | sort | \
  uniq > /tmp/only_make_unique.txt
diff --new-line-format="" --unchanged-line-format="" \
  /tmp/only_make_unique.txt /tmp/memory.txt | \
  xargs grep -l "absl/memory" > /tmp/add-memory.txt

git grep -l "\babsl::make_unique\b" | \
  xargs sed -i "s/\babsl::make_unique\b/std::make_unique/g"

git checkout PRESUBMIT.py abseil-in-webrtc.md

cat /tmp/add-memory.txt | \
  xargs sed -i \
  's/#include "absl\/memory\/memory.h"/#include <memory>/g'
git cl format
# Manual fix order of the new inserted #include <memory>

a370556270 Refactor to free up PacketBuffer as soon as possible
The packets belonging to a frame were kept in PacketBuffer
until the frame was decoded. This CL clears the dependencies
of an existing RtpFrameObject to PacketBuffer so that we can
free up PacketBuffer as soon as the RtpFrameObject is created.

f00bf42d1c Add plumbing of RtpPacketInfos to each VideoFrame as input for SourceTracker.
This change adds the plumbing of RtpPacketInfo from RtpVideoStreamReceiver::OnRtpPacket() to VideoReceiveStream::OnFrame() for video. It is a step towards replacing the non-spec compliant ContributingSources that updates itself at packet-receive time, with the spec-compliant SourceTracker that will update itself at frame-delivery-to-track time.

abbc50e9b2 Move frame_type member from RtpDepacketizer::ParsedPayload to RTPVideoHeader
The latter is also a member of the former. This cleanup is also
a preparation for dropping WebRtcRTPHeader::frameType (or deleting
WebRtcRTPHeader right away), now that it's a video-specific member.

a556448138 Don't recreate the VideoReceiveStream on SetFrameDecryptor in the MediaEngine.
This change introduces new logic to allow the injection of the FrameDecryptor
into an arbitrary already running VideoReceiveStream without resetting it. It
does this by taking advantage of the BufferedFrameDecryptor which will
forcefully be created regardless of whether a FrameDecryptor is passed in
during construction of the VideoReceiver if the
crypto_option.require_frame_encryption is true. By allowing the
BufferedFrameDecryptor to swap out which FrameDecryptor it uses this allows the
Receiver to switch decryptors without resetting the stream.

This is intended to mostly be used when you set your FrameDecryptor at a point
post creation for the first time.

52426edef1 Modify BufferedFrameDecryptor to perform fine grained key requests.
The current Key Frame request system doesn't take into account failed
decryptions and this can lead to WebRTC spamming new key frame requests when
the issue is actually in the decryptor layer. To prevent this if frame
decryption is required for the PeerConnection key frame requests will not be
sent at 200ms intervals but will wait until the stream is decryptable before
utilizing this logic.

00765297a2 Add BufferedFrameDecryptor to cleanly deal with receiving encrypted frames.
This change introduces a new class BufferedFrameDecryptor that is responsible
for decrypting received encrypted frames and passing them on to the
RtpReferenceFinder. This decoupling refactoring was triggered by a new
optimization also introduced in this patch to stash a small number of
undecryptable frames if no frames have ever been decrypted. The goal of this
optimization is to prevent re-fectching of key frames on low bandwidth networks
simply because the key to decrypt them had not arrived yet.

The optimization will stash 24 frames (about 1 second of video) in a ring buffer
and will attempt to re-decrypt previously received frames on the first valid
decryption. This allows the decoder to receive the key frame without having
to request due to short key delivery latencies. In testing this is actually hit
quite often and saves an entire RTT which can be up to 200ms on a bad network.

As the scope of frame encryption increases in WebRTC and has more specialized
optimizations that do not apply to the general flow it makes sense to move it
to a more explicit bump in the stack protocol that is decoupled from the WebRTC
main flow, similar to how SRTP is utilized with srtp_protect and srtp_unprotect.

One advantage of this approach is the BufferedFrameDecryptor isn't even
constructed if FrameEncryption is not in use.

I have decided against merging the RtpReferenceFinder and EncryptedFrame stash
because it introduced a lot of complexity around the mixed scenario where some
of the frames in the stash are encrypted and others are not. In this case we
would need to mark certain frames as decrypted which appeared to introduce more
complexity than this simple decoupling.
