7deade8577 mixer: protect the mixer struct with a mutex 
In some rare cases, there was a race condition between the output
thread and the main thread: when you disable/enable an output device
in the main thread, this caused a crash in the output thread.  Protect
the whole mixer struct with a GMutex to prevent that.

a5017a2d7c mixer_api: moved functions to mixer_control.c 
mixer_control.h should provide the functions needed to manipulate a
mixer, without exposing the internal mixer API (which is provided by
mixer_api.h).

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.

a547d24eb2 mixer: check for init() failures 
When the init() method of a mixer plugin fails, mixer_new()
dereferences the NULL pointer.

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().

936449c622 mixer_api: removed struct mixer_data 
The mixer plugins should re-use the mixer struct and incorporate it in
their object class.

dc575106c2 mixer: merged methods "init" and "configure" 
Both methods are always called together.  There is no point in having
them separate.  This simplifies the code, because the old configure()
method could be called more than once, and had to free old
allocations.

8695b94232 mixer: removed mixer_configure(), configure mixer in mixer_new() 
Allocate the mixer object when it is configured.

Merged mixer_configure() into mixer_new().  mixer_new() was quite
useless anyway.
