725e48fce4 pcm_resample: add function pcm_resample_float()
A version of the resampler that doesn't need int->float->int
conversion.

2b3fd0d4d3 pcm_resample: one-time global initialization
Load the samplerate_converter on MPD startup.  Fail if the converter
name is invalid.

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.

7c13249b59 pcm_resample: fixed typo in libsamplerate runtime check
The string comparison should be "!= 0", not "== 0".  Ouch.

e12140cfce pcm_resample: choose the fallback resampler at runtime
Even if libsamplerate support is enabled, compile the fallback
resampler.  When the user specifies the option
"samplerate_converter=internal", it is chosen in favor of
libsamplerate.  This may help users with a weak FPU who don't want to
compile a custom MPD from source, because the fallback resampler does
not use floating point operations.

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.

bb08679a70 pcm_resample: use pcm_buffer (2/2)
Use the PCM buffer library for the libsamplerate output buffer.

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

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.
