Currently, when we generate the list of supported video codecs that will
be signaled in SDP, we start with the internal video codecs and then
append the external video codecs. When we create a video encoder for a
given codec, we prefer an external encoder over an internal encoder.
This CL lists the external video codecs first in SDP instead, so that we
consistently prefer external video codecs over internal.
The reason for doing this is that we will otherwise prefer an internal
SW H264 encoder over an external HW H264 encoder if the H264 profiles
differs.

Replace the use of webrtc::VideoEncoderFactory with
cricket::WebRtcVideoEncoderFactory and remove the adapter classes
between these two factory types.
Some code changes were necessary in order to accomplish this:
* Move SimulcastEncoderAdapter from
webrtc/modules/video_coding/codecs/vp8 to webrtc/media/engine (that's
where it's used).
* Rename simulcast_unittest.h to simulcast_test_utility.h and make it
into it's own target, because it's used from both
simulcast_unittest.cc and simulcast_encoder_adapter_unittest.cc.
* Remove ownership of the encoder factory from SimulcastEncoderAdapter,
and make the necessary changes in surrounding code.
The goal with this CL is to clean up the code, and also to free up
the name webrtc::VideoEncoderFactory for future use.

Some frames are already marked as 'timing frames' via video-timing RTP header extension. Timestamps along full WebRTC pipeline are gathered for these frames. This CL implements reporting of these timestamps for a single
timing frame since the last GetStats(). The frame with the longest end-to-end delay between two consecutive GetStats calls is reported.
The purpose of this timing information is not to provide a realtime statistics but to provide debugging information as it will help identify problematic places in video pipeline for outliers (frames which took longest to process).

I used a command like this to update the paths:
perl -pi -e "s/webrtc\/base/webrtc\/rtc_base/g" `find webrtc/rtc_base -name "*.cc" -o -name "*.h"`

Timing information is gathered in EncodedImage,
starting at encoders. Then it's sent using RTP header extension. In the
end, it's gathered at the GenericDecoder. Actual reporting and tests
will be in the next CLs.

WebRtcVideoChannel and and WebRtcVideoEngine seem to have been removed, and only WebRtcVideoChannel2 and WebRtcVideoEngine2 remain, which removes the need for the "2" postfix.
