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.

cba126ceb8 pcm_resample_fallback: don't include glib.h
This library does not use GLib directly.

456201fa22 pcm_resample: renamed implementation functions
Added diversion functions to pcm_resample.c.  These check which
resampler is enabled at compile time (libsamplerate or fallback).
This prepares the following patch.

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.

d9c1434298 pcm_resample: use 24 bit resampling code for 32 bit samples
Resampling 32 bit samples is the same as resampling 24 bit samples -
both are stored in the int32_t type.

953b258e5e pcm_resample_fallback: corrected the sample calculation
Due to rounding errors, it was possible that the fallback resampler
returned partial frames.

2a83138913 pcm_resample: use pcm_buffer (1/2)
Return a temporary buffer from pcm_resample_*() and pcm_convert().

7f34e9410e pcm: added pcm_convert_deinit(), pcm_resample_deinit()
Free memory allocated by libsamplerate when the output or the decoder
is closed.

af7cb932fb pcm_resample: implemented 24 bit resampling
Similar to pcm_resample_16(), implement pcm_resample_24().  The 24 bit
implementation is very similar, but it uses src_int_to_float_array()
instead of src_short_to_float_array() before sending data to
libsamplerate.

1dcb946fb0 pcm_resample: eliminated "sample" local variables
Copy from source to destination buffer directly, don't use the
temporary variables "lsample" and "rsample".

124f79a2a6 pcm_resample: don't resample partial samples
Added assertions which ensure that there are no partial samples in the
source buffer.

b13d656f81 pcm_resample: don't hard-code sample size
Use sizeof(sample) instead of hard-coding "2".  Although we're in 16
bit right now, this will make code sharing easier when we support
other sample sizes.

6b1c54ef96 pcm_utils: moved code to pcm_resample.c
Separate the resampling code from the rest of pcm_utils.c.  Create two
sub-libraries: pcm_resample_libsamplerate.c and
pcm_resample_fallback.c.
