These decoders have been moved into their own subfolders under the
extras/decoders folder:
extras/decoders/libvorbis
extras/decoders/libopus
In addition to being relocated, they have also been split into separate
.c/h pairs. They now work like a more conventional library. The
implementation of these libraries have also been decoupled from the
miniaudio implementation which means they depend only on the header
section of miniaudio.h now.
With this change the custom_decoder and custom_decoder_engine examples
have been updated. To compile these you now need to link in the
miniaudio_libvorbis.c and miniaudio_libopus.c files via your build
tool. For your own code, you can still include the .c files directly
into your code if you want to compile as a single translation unit.
The data source implementation of a ma_pcm_rb could possibly return a
frame count of 0 which would in turn result in
ma_data_source_read_pcm_frames() returning MA_AT_END which does not
make sense for a ring buffer since it has no notion of an end.
This is useful because MA_ASSERT is only defined in the implementation
section of miniaudio.h which can cause issues when people copy/paste
the code and use it in a file that does not have visibility of the
implementation.
Note that there are still more references to implementation-defined
macros, but these have been moved to the public section in the dev-0.12
branch so I'm not bothering to change those just yet.

With this commit, custom backends can now be implemented as
self-contained modules that can easily be plugged in and mixed and
matched depending on a programs requirements. The order in which
custom backends are specified in the context config determine their
priority.
This commit updates the custom_backend example by moving the SDL
code out into its own file in "extras/backends/sdl". The example will
now just include the SDL code files like normal. This represents a more
realistic scenario.
