This fixes issue https://github.com/obsproject/obs-studio/issues/6295 .
libvlc does some downmixing/upmixing when the number of channels
requested is less than the number of channels of the source.
We take advantage of that feature to avoid doing it with swresample
because we're missing info that libvlc is not giving (the exact channel
layout of the source).

The vlc plugin was keeping only up to two audio channels. It was overlooked when surround sound support was added to obs-studio. This commit remedies this oversight.

Makes the signal's behavior on-par with `obs_source_media_started`.
`obs_source_media_started` is emitted every time a file in the playlist
is played, and so therefore should `obs_source_media_ended`. In this
scenario, the loop setting is actually irrelevant to the behavior that
this signal should have.
Casting from char[] to uint32_t * is considered undefined behavior due
to different alignment requirements. Instead of using char[] for the new
value, this uses a macro to set a uint32_t directly.

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.
libvlc_media_new_path implies a file. To get media based upon URLs, use
libvlc_media_new_location. Additionally, if using a URL, it's best to
give it some playback caching/buffering, at least 100 milliseconds.
Closesjp9000/obs-studio#590
libVLC doesn't seem to provide full speaker configuration info, so when
downmixing audio from a file that had more than 2 channels, the audio
would sound wrong.
This change makes it so that libVLC does the downmixing to stereo rather
than libobs, just due to that lack of speaker configuration info.
Adds the ability to add video playlists via libvlc instead of via the
media source. This is mostly just being added as a secondary option to
the media source to reduce maintenance costs and save time. Currently
libff cannot pause/unpause/seek, and isn't programmed to handle
playlists yet.
If VLC is installed on the computer (with the same architecture) it will
allow video playback via libVLC. In the future, users should be able to
optionally download VLC libraries via the installer as well if they
don't want to necessarily install VLC to get the plugin working.
This plugin performs runtime linking instead of compile-time linking;
compiling VLC is not required, only its headers are required. To
compile, clone the VLC repository and set the VLCPath cmake variable to
point to the VLC repository directory.
