Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed.  Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.

(This commit also modifies the following modules: UI,
deps/media-playback, coreaudio-encoder, decklink, linux-alsa,
linux-pulseaudio, mac-capture, obs-ffmpeg, obs-filters, obs-libfdk,
obs-outputs, win-dshow, and win-wasapi)

Adds surround sound audio support to the core, core plugins, and user
interface.

Compatible streaming services: Twitch, FB 360 live
Compatible protocols: rtmp / mpeg-ts tcp udp
Compatible file formats: mkv mp4 ts  (others untested)
Compatible codecs: ffmpeg aac, fdk_aac, CoreAudio aac,
		   opus, vorbis, pcm (others untested).
Tested streaming servers: wowza, nginx
	 HLS, mpeg-dash : surround passthrough
Html5 players tested with live surround:
	 videojs, mediaelement, viblast (hls+dash), hls.js
Decklink: on win32, swap channels order for 5.1 7.1
         (due to different channel mapping on wav, mpeg, ffmpeg)
Audio filters: surround working.
Monitoring: surround working (win macOs linux (pulse-audio)).
VST:	 stereo plugins keep in general only the first two channels.
	 surround plugins should work (e.g. mcfx does).
OS: win, macOs, linux (alsa, pulse-audio).
Misc: larger audio bitrates unlocked to accommodate more channels
NB: mf-aac only supports mono and stereo + 5.1 on win 10
         (not implemented due to lack of usefulness)

Closes jp9000/obs-studio#968

This is to prevent confusion both when prefixing commits and when
reading the directory structure for the first time.

(Note: This commit also modifies coreaudio-encoder, win-capture, and
win-mf modules)

This reduces logging to the user's log file.  Most of the things
specified are not useful for examining log files, and make reading log
files more painful.

The things that are useful to log should be up to the front-end to
implement.  The core and core plugins should have minimal mandatory
logging.

When an encoder has been removed (such as CoreAudio) and the audio
bitrates currently configured no longer are available to the current
audio encoders anymore, it would cause GetAACEncoderForBitrate to return
false with no encoder available.

To fix the issue, instead just choose the closest bitrate relative to
the current bitrate (rounded up).

Adds Microsoft Media Foundation AAC Encoder that supports
96k to 192k bitrates.  This plugin is only enabled on Microsoft
Windows 8+ due to performance issues found on Windows 7.
