This CL will start to distinguish H264 profiles during SDP negotiation.
We currently don't look at the H264 profile at all and assume they are
all Constrained Baseline Level 3.1. This CL will start to check profiles
for equality when matching, and will generate the correct answer H264
level.
Each local supported H264 profile needs to be listed explicitly in the
list of local supported codecs, even if they are redundant. For example,
Baseline profile should be listed explicitly even though another profile
that is a superset of Baseline is also listed. The reason for this is to
simplify the code and avoid profile intersection during matching. So
VideoCodec::Matches will check for profile equality, and not check if
one codec is a subset of the other. This also leads to the nice property
that VideoCodec::Matches is symmetric, i.e. iif a.Matches(b) then
b.Matches(a).

It would be enough to say we're removing EnableSrtpDebugging because
it's never called, but the story is a bit more interesting.
libsrtp's debugging facilities are gated behind the reasonably-named
ENABLE_DEBUGGING macro:
b17c065a8a/srtp/crypto/include/err.h (186)
This code was imported to WebRTC from libjingle, but neither WebRTC or
Chromium ever set ENABLE_DEBUGGING. Even if someone had ever called
EnableSrtpDebugging, it wouldn't have done anything.

This CL is a pure refactoring which should not result in any functinal
changes. It moves ownership of the RtcEventLog from webrtc::Call to the
webrtc::PeerConnection object.
This is done so that we can add RtcEventLog support for ICE events -
which will require the TransportController to have a pointer to the
RtcEventLog. PeerConnection is the closest common owner of both Call and
TransportController (through WebRtcSession).

This should bring back the build behavior we used to have with GYP

The only real difference between the two is that SetRtcpTransportChannel
had a workaround to prevent a signal from being emitted early.
Basically, in SetTransport, we want to switch the transport channels and
*then* update the state, rather than updating the state after changing
only one transport channel.
But this can be accomplished more easily by simply updating the state in
SetTransport directly.

Normally, when creating a data channel with an out-of-range ID,
createDataChannel returns nullptr. But due to an off-by-one
error, creating a data channel with ID 1023 returns a data channel
that silently fails later.
This probably occurred because it wasn't clear whether "kMaxSctpSid" was an
inclusive or exclusive maximum, so I changed the value to
"kMaxSctpStreams". This wasn't caught by unit tests because the
off-by-one error persisted to the unit tests as well.
Also getting rid of some dead code. We were adding SCTP streams to the
ContentDescription object but they weren't being used.

This change makes WebRTC no longer stop sending video when we receive an
EWOULDBLOCK error from the operating system. This was previously
causing calls on a slow link (where the first hop is slow) to rapidly
oscillate between starting and stopping video.
We still do need to stop sending packets if there is no known good
connection we can use for that. We used to generate a synthetic
EWOULDBLOCK error in that case. This CL replaces it with a different
code (ENOTCONN); EWOULDBLOCK no longer stops the stream but ENOTCONN
does.
I've updated all the places where we seemed to be generating EWOULDBLOCK
for reasons other than some buffer been full; please give it a thorough
look in case I missed something.
