This changes the way backends update the internal data format in
response to a device reroute. With this change we'll be able to remove
the `channelMap` and `internalChannel` map members from the `ma_device`
struct which should reduce its size by ~1KB.
This changes `write_pcm_frames()` so that when `pFramesWritten` is null,
the write is treated as all or nothing. If the entire write cannot be
performed, nothing at all will be written and `MA_NO_SPACE` will be
returned. The same applies with `read_pcm_frames()` and `pFramesRead` in
which case `MA_NO_DATA_AVAILABLE` will be returned.
The reason for this change is that if the called passes in null for
these values, they'll have no way to know how many frames were actually
written or read. Therefore the most practical way to treat it is as all
or nothing.
This is a wrapper around `ma_ring_buffer` and is more specialized
towards audio. It is a data source and replaces `ma_pcm_rb` which will
be removed in a future commit.

This improves on the old ring buffer by having a much simpler
implementation and a much simpler API that does not require the caller
to do reading and writing in a loop.
Future commits will be removing the old ring buffer.

This uses `getDisplayMedia()`. Support for this is extremely browser and
system specific so I'm not advertising support for this documentation.

The `onGetEncodingFormat` callback has been removed and replaced with an
`onInfo`. This new callback fills out a struct with the supported
encoding format (is recognized by miniaudio), in addition to the name of
the decoding backend, and the decoding library and vendor.
* Devices are now enumerated properly. It will enumerate input or output
ports depending on the device type, and then group by the client name.
The client name will be considered a "device" from the perspective of
miniaudio. The number of local ports will be the channel count.
* The port auto-connection process is now done in init() rather than
start(). I do not know why this was ever in start() in the first
place.
* Port auto-connection will now be restricted to the client ports. The
old system would connect across multiple clients which is just a
nonsensical way of doing. If more ports are requested than are
available on the client, the excess ports will just not be connected.
