OBS already handles a couple of different audio formats, this expands
alsa input to try these additional formats for devices with weird format
support.

RNNoise symbols may collide with external ones provided by
libcodec2.so which FFMPEG may pull in automatically. Changing
the visibility of these symbols will guarantee the use of the
internal ones and not pick some (potential incompatible) from
outside.

For some reason, currently unknown, FFmpeg logging has to be set to
something in order for HLS to not fail on Windows, even if it's just an
empty function.
(Author comment: I don't feel comfortable not knowing why, my theory is
that FFmpeg has an issue with this internally with HLS on Windows
related to logging or how it's trying to log, I have absolutely no idea
what's going on and if someone can enlighten me or debug FFmpeg itself
it'd be real nice to know why.)
Adds a cmake variable (DEBUG_FFMPEG_MUX) which enables FFmpeg debug
output in the ffmpeg-mux subprocess, and if on Windows, shows the
console window of the ffmpeg-mux subprocess so the current output can be
seen.
For game capture, hook DXGI release function to release D3D objects if
the related swap chain is also being destroyed.
An added bonus is that the game capture hook will handle swap chain
recreation for applications that don't use ResizeBuffers.
Add and register an obs_output_info struct called
ffmpeg_hls_muxer. It uses ffmpeg's HLS muxer to stream output.
Add threading and buffer to reduce skipped frames.
Also add frame drop logic when there are too many packets in the
buffer for congestion control.
(Jim) Allows the ability to use stream keys with ffmpeg-mux -- this will
enable the ability to use it with certain services (such as YouTube)
which allow different protocols (such as HLS)
(Jim) Allows the ability to specify mux settings directly on the
output's structure itself rather than just via settings. This is useful
for network-based muxer outputs (such as HLS).
(Jim) printable_file allows the ability to keep a separate string for
logging which will not contain things like stream keys when used with
outputs such as HLS.
(Jim) Allows the ability to get a link from the service's settings about
a specific service selection the user chooses and display it as a "More
Info" button that the user can click to find out more information about
that particular service.
The frontend API event OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED was not
being triggered when hotkeys were used because it was only set to
trigger when the replay buffer button was clicked, not when a hotkey was
used. This fixes it so that the frontend event sends a signal to the
frontend so that hotkeys will actually work.
The path of coreaudio dll has changed in current versions of iTunes on
windows. The patch fixes the issue while keeping compatibility with
previous path.

EVGA/magewell devices seem to use the default system drivers rather than
custom drivers, which causes their audio to become decoupled and treated
as completely separate devices rather than as an audio pin on the video
device. Basically, this would cause those devices to not have audio by
default, and force the user to have to manually select the audio, which
is bad user experience.
We already had a workaround for this with elgato devices, so expand that
code to become a whitelist of devices, and include EVGA/magewell
devices.
Rivatuner Statistics Server calls vkGetInstanceProcAddr for
vkCreateDevice with a NULL instance. According to spec, this should
return NULL, but RTSS will dereference this and crash.
This change returns function pointers for every intercepted function
regardless of instance, which is enough to keep RTSS alive.
ffmpeg-mux does not notice if ffmpeg returns an error from
av_interleaved_write_frame() which means that OBS never knows if there is a
problem in ffmpeg.
This is the biggest issue for cases like srt:// or tcp:// streams that can
regularly fail. Without this change OBS never knows that something went wrong.
