Rewrites the hardware decoding system with C++-style code instead of
C-style.

Removes support for hardware decoding h263, as we do not use the h263p
decoder, which is the codec with hardware support.

When decoding files, their audio is rematrixed to mono or stereo
depending on the negotiated format. Libswresample does not support
rematrixing from Dolby Surround 5.1, so skip over streams with this
layout. If the file only contains Dolby 5.1, switch back to default
audio input device.

If MediaDecoder::getStream is called before any frames are decoded,
lastTimestamp_ remains uninitialized.

1. Adds constness to streams in MediaRecorder; the latter shouldn't change
stream parameters.
2. addStream is called from recordData to simplify workflow; users need
only check that MediaRecorder is recording.
3. Fixes regression where multiple records couldn't happen in the same
call.
4. Fixes AudioSender not sending starting timestamp to help mix audio.
5. MediaStream::name is now used as key for the streams_ map, so it must
be constant, filter names are no longer hardcoded in the recorder.
6. fromPeer parameter is determined by checking if MediaStream::name
contains the string "remote".
7. Adds copy constructor to MediaStream.
8. Renames incrementStreams to incrementExpectedStreams to better reflect
what it does.
9. Removes keyframe triggers when starting a video record; we are
recording raw frames, so it doesn't matter if they're keyframes or not.
10. MediaRecorder supports more than 2 audio streams, but not video.
11. Move preview to very bottom right corner.
12. Fix potential Unchecked Return Value to NULL Pointer Dereference in
recordData() (CWE-690).

If FFmpeg was unable to find a framerate in avformat_find_stream_info,
fall back to the DeviceParams' framerate.

This was the case for certain Macs.

This is redundant, the information can already be found in the AVStream
object and is set by avcodec_parameters_to_context. Let FFmpeg take care
of these details.

Moves the recorder up one level to the VideoInput, VideoReceiveThread
and AudioReceiveThread, instead of the MediaDecoder (there's no
equivalent to the VideoInput in the audio layer).

Emits the RecordPlaybackStopped when the recording is stopped, so the
client can sync its recording state with the daemon, in case the daemon
stops recording by itself (rather than user intervention).

It better explains what the method does, as the recorder is not started

Falling back from hardware to software decoding requires only a
reinitialization of the AVCodecContext. Hardware decoding failure is no
longer bubbled up to the RTP session, which makes it much faster.

libavutil now covers the simple cases for creating and managing devices.
As Ring does not need to fine-tune these processes, most of the accel
code can be and has been removed.

Most hardware decoders output NV12, so skip extra conversions by
outputting NV12. Said pixel format is supported by everything that isn't
excessively old.

Correctly wraps video preferences and hardware acceleration
in ifdef preprocessor statements (RING_VIDEO and RING_ACCEL,
respectively). This fixes cases where Ring would not compile without
video or video acceleration. Video acceleration is now dependant on
the presence of video (--disable-video disables acceleration).

Change-Id: I087cc1dc794d0f19daa68cdaec09e126542147f9

Hardware acceleration is now correctly enabled/disabled using Ring's
config file. The setting was moved from DeviceParams/VideoSettings,
which are used for local video, to preferences under video.

The video preferences object calls serialize() on the video device
preferences, so as to not overwrite one another (they're under the
same section in the config file).
