acc4a0ba2d output: make "struct audio_output" opaque for output plugins
We have eliminated direct accesses to the audio_output struct from
the all output plugins.  Make it opaque for them, and move its real
declaration to output_internal.h, similar to decoder_internal.h.

Pass the opaque structure to plugin.init() only, which will return the
plugin's data pointer on success, and NULL on failure.  This data
pointer will be passed to all other methods instead of the
audio_output struct.

63fb1efb5c output: added audio_output_closed()
The JACK output plugin needs to reset its "opened" flag when the JACK
server fails.  To prevent it from accessing the audio_output struct
directly introduce the API function audio_output_closed().

3be5db0430 output: added audio_output_get_name()
Reduce direct accesses to the audio_output struct from the plugins:
this time, eliminate all accesses to audio_output.name.  The name is
required by some plugins for log messages.

3cae6856b8 output: pass audio_format to plugin.init() and plugin.open()
Pass the globally configured audio_format as a const pointer to
plugin.init().  plugin.open() gets a writable pointer which contains
the audio_format requested by the plugin.  Its initial value is either
the configured audio_format or the input file's audio_format.

d32f49a90b output: one thread per audio output
To keep I/O nastiness and latencies away from the core, move the audio
output code to a separate thread, one per output.  The thread is
created on demand, and currently runs until mpd exits.

3aa4564b56 output: removed audio_output.sameInAndOutFormats
Eliminate sameInAndOutFormats and check with audio_format_equals()
each time it this information is needed.  Another 4 bytes saved.

56cf54e880 output: removed audio_output.convertAudioFormat
Instead of checking convertAudioFormat, we can simply check if
reqAudioFormat is defined.  This saves 4 bytes in the struct.

755d55075d output: renamed method names
No CamelCase.  Also don't declare typedefs for the methods.

3f6fe915eb output: const plugin structures
Since the plugin struct is never modified, we should store it in
constant locations.

a0103dd05c output: replace audio_output.*Func with audio_output.plugin
Instead of copying all that stuff from the audio output plugin to the
audio output structure, store a pointer to the plugin.

3b09c54b67 output: renamed typedef AudioOutput to struct audio_output
Also rename AudioOutputPlugin to struct audio_output_plugin, and use
forward declarations to reduce include dependencies.

bed2a49fe9 output: added output_api.h
Just like decoder_api.h, output_api.h provides the audio output API
which is used by the plugins.
