35151f35ec Add histogram stats for average send delay of sent packets for a sent video stream. The delay is measured from a packet is sent to the transport until leaving the socket.
- "WebRTC.Video.SendDelayInMs"

Change so that PacketOption packet id is always set in RtpSender (if having a TransportSequenceNumberAllocator).
Add SendDelayStats class for computing delays.
Add SendPacketObserver to RtpRtcp config and register SendDelayStats as observer.
Wire up OnSentPacket to SendDelayStats.

5f0b83b7fb Enabling rtcp-rsize negotiation and fixing some issues with it.
Sending of reduced size RTCP packets should be enabled only if it's
enabled in the send parameters (which corresponds to the remote description).

Since the RTCPReceiver's RtcpMode isn't used at all, I removed it to ease
confusion.

10880011d9 Support multiple rtx codecs.
Adds negotiation of rtx codecs for red and vp9. To keep backwards
compatibility with older Chrome versions, this change includes two
hacks:
1. Red packets will be retransmitted over the rtx codec associated with
   vp8 if no rtx codec is associated with red. This is how Chrome does
   it today and ensures that we still can send red over rtx to older
   versions.

2. If rtx packets associated with the media codec (vp8/vp9 etc) are
   received and red has been negotiated, we will assume that the sender
   incorrectly has packetized red inside the rtx header associated with
   media. We will therefore restore it with the red payload type
   instead, which ensures that we can still receive rtx associated with
   red from old versions.

Offering multiple rtx codecs to older versions should not be a problem
since old versions themselves only try to negotiate rtx for vp8.

ac547a6538 Remove channel ids from various interfaces.
Starts by removing channel/engine id from ViEChannel which propagates
down to the RTP/RTCP module as well as the transport class.

IncomingVideoStream::RenderFrame() is untouched for now but receives a
fake id instead of the previous channel id. Added a TODO to remove it
later but the RenderFrame call is implemented in a lot of
platform-dependent files and should probably remove the "manager" aspect
of renderers, so preferring to do it separately

91d6edef35 Add RTC_ prefix to (D)CHECKs and related macros.
We must remove dependency on Chromium, i.e. we can't use Chromium's base/logging.h. That means we need to define these macros in WebRTC also when doing Chromium builds. And this causes redefinition.

Alternative solutions:
* Check if we already have defined e.g. CHECK, and don't define them in that case. This makes us depend on include order in Chromium, which is not acceptable.
* Don't allow using the macros in WebRTC headers. Error prone since if someone adds it there by mistake it may compile fine, but later break if a header in added or order is changed in Chromium. That will be confusing and hard to enforce.
* Ensure that headers that are included by an embedder don't include our macros. This would require some heavy refactoring to be maintainable and enforcable.
* Changes in Chromium for this is obviously not an option.

242e22b055 Refactor RTCP sender
The main purpose of this CL is to clean up RTCPSender::PrepareRTCP, but
it has quite a few ramifications. Notable changes:

* Removed the rtcpPacketTypeFlags bit vector and don't assume
  RTCPPacketType values have a single unique bit set. This will allow
  making this an enum class once rtcp_receiver has been overhauled.

* Flags are now stored in a map that is a member of the class. This
  meant we could remove some bool flags (eg send_remb_) which was
  previously masked into rtcpPacketTypeFlags and then masked out again
  when testing if a remb packet should be sent.

* Make all build methods, eg. BuildREMB(), have the same signature.
  An RtcpContext struct was introduced for this purpose. This allowed
  the use of a map from RTCPPacketType to method pointer. Instead of
  18 consecutive if-statements, there is now a single loop.
  The context class also allowed some simplifications in the build
  methods themselves.

* A few minor simplifications and cleanups.

The next step is to gradually replace the builder methods with the
builders from the new RtcpPacket classes.

Reformat to current code style, remove non-const references, use
scoped_ptr, remove empty comments and dead code, etc..

fe7a80c38c Prevent sender RTCP signals for receive-only channels.
Since RTCP packets are delivered to both senders and receivers that
correspond the receivers currently log that NACKed packets are missing,
since they have no direct connection to the sending side or the RTP
packet history. Also preventing triggering on SR requests and PLI/FIR.

e62202fedf Support handling multiple RTX but only generate SDP with RTX associated with VP8.
This implementation registers RTX-APT map inside RTP sender and receiver.
While it only generates SDP with RTX associated with VP8 to make it
compatible with previous Chrome versions.

Should add following changes after reaches stable,
* Use RTX-APT map for building and restoring RTP packets.
* Add RTX support for RED or VP9 in Video engine.
* Set RTX payload type for RED inside FecConfig in EndToEndTest.
