0aee49bdf8 all: Update copyright header.
This updates the copyright header to all be the same, which is
pretty much an update of where to mail request for a copy of the GPL
and the years of the MPD project. This also puts all committers under
'The Music Player Project' umbrella. These entries should go
individually in the AUTHORS file, for consistancy.

0cf4f09e4f output_api: removed audio_output_get_name()
Use config_get_block_string("name") instead of audio_output_get_name().

585f81ece1 output_api: don't include config.h
If an output plugin requires config.h, it should include it directly.

83ce0e5325 mixer_api: replaced method "control()" with "{get,set}_volume()"
The method control() is too complicated, and overengineered.  Replace
it with two trivial functions: get_volume() and set_volume().

80702fa3a2 output_api: moved "struct audio_output_plugin" to output_plugin.h
If we move the plugin struct to a separate header, we don't have to
include the big fat output_api.h everywhere.

a5c0394007 output_api: moved "enum output_command" to output_internal.h
Now that the output_command enum isn't exposed to output plugins
anymore, we can hide its definition within output_internal.h.

e2f22229a6 output_api: include "config.h" without "../"
Including "../config.h" breaks on some systems.

231636b9eb output_api: moved the command check out of method pause()
Move the "while" loop which checks for commands to the caller
ao_pause().  This simplifies the pause() method, and lets us remove
audio_output_is_pending().

a2e0b71aad output_api: removed audio_output_closed()
The function is only used by the MVP output plugin, and this one call
is wrong.

ea515494cb added prefix to header macros
"LOG_H" is a macro which is also used by ffmpeg/log.h.  This is
ffmpeg's fault, because short macros should be reserved for
applications, but since it's always a good idea to choose prefixed
macro names, even for applications, we are going to do that in MPD.

58c5bee9f0 output: use bool for return values and flags
Don't return 0/-1 on success/error, but true/false.  Instead of int,
use bool for storing flags.

71351160b1 don't include os_compat.h

os_compat.h.

6e21e24cae audio_output: added method pause()
pause() puts the audio output into pause mode: if supported, it may
perform a special action, which keeps the device open, but does not
play anything.  Output plugins like "shout" might want to play silence
during pause, so their clients won't be disconnected.  Plugins which
do not support pausing will simply be closed, and have to be reopened
when unpaused.

This pach includes an implementation for the shout plugin, which
sends silence chunks.

c13e8b5146 audio_output: added function audio_output_is_pending()
The function audio_output_is_pending() returns whether there is a
pending command.  This is useful for output plugins as a break
condition for longer loops.

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.

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.

a0103dd05c output: replace audio_output.*Func with audio_output.plugin

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.
