c412d6251e audio_format: changed "bits" to "enum sample_format" 
This patch prepares support for floating point samples (and probably
other formats).  It changes the meaning of the "bits" attribute from a
bit count to a symbolic value.

5b82ffc291 include config.h in all sources 
After we've been hit by Large File Support problems several times in
the past week (which only occur on 32 bit platforms, which I don't
have), this is yet another attempt to fix the issue.

54889c72e3 pcm_convert: use GError for error handling 
Don't abort the whole MPD process when the conversion fails.  This has
been a denial-of-service attack vector for years.

172a1dbdb9 pcm_byteswap: converted NULL checks to assertions 
It is illegal to pass a NULL buffer to pcm_byteswap_X().  The result
of this is that pcm_byteswap_X() never returns NULL.

c5a662f405 pcm_convert: added pcm_convert_state.byteswap_buffer 
Currently, byteswapping is performed on the format_buffer.  This can
go wrong when this buffer is used twice during one run.  Add a
separate buffer for swapping the byte order.

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.

a5a15beac2 pcm_convert: added 32 bit support 
All PCM sub libraries have 32 bit support now.  Add support to the
glue function pcm_convert().

656d5c9c7b pcm_convert: removed pcm_convert_size() 
The function is unused, since we added the pcm_buffer library.

356526457c pcm_convert: return PCM buffer from pcm_convert() 
Removed yet another superfluous buffer layer: return the PCM buffer
from pcm_convert() instead of copying PCM data into the
caller-supplied buffer.

29baf0c190 log, pcm_convert: added return statements after g_error() 
gcc doesn't know that g_error() never returns.  Work around the gcc
warning.

6139174d81 pcm_convert: removed unused variable "dest_size" 
dest_size is only used in an assertion.  Remove its declaration and
move the formula into the assertion.

is closed.

04a2138b33 pcm: pass void pointers to PCM functions 
In generic PCM functions allowing all sample formats, pass a void
pointer instead of a char pointer.

b40428b3fd pcm_utils: moved conversion code to pcm_convert.c 
All what's left in pcm_utils.h is the pcm_range() utility function,
which is only used internally by pcm_volume and pcm_mix.
