a2b5db0003 audio_format: remove SAMPLE_FORMAT_DSD_OVER_USB
DSD-over-USB should not be a MPD core format, because it is not a
"natural" format; it is just a temnporary over-the-wire format.  This
format has been implemented in pcm_export, and does not need to be
supported by pcm_convert.

b99ecb4dc9 audio_format: remove the packed S24 format
For simplicity, the MPD core should not have to deal with packing.  It
is rarely used, and those plugins that need it should use the
pcm_export library instead.

8c5ebdff36 audio_format: remove the reverse_endian attribute
Eliminate support for reverse endian samples from the MPD core.  This
moves a lot of complexity to the plugins that really need it (only
ALSA and CDIO currently).

9c6a4505c8 audio_format: remove the format SAMPLE_FORMAT_DSD_LSBFIRST
This format is unused since the DSDIFF decoder plugin now reverses the
bit order.

2516496993 audio_format: add DSD sample format
Basic support for Direct Stream Digital.  No conversion yet, and no
decoder/output plugin support.

20c6159c04 pcm_dither: pass an "end" pointer instead of a sample count
This is easier and more efficient to loop on, because only two
variables get modified (src and dest).

5cf4ce9318 pcm_format: fix 32-to-24 bit conversion (the "silence" bug)
D'oh, we were reading 16 bit integers instead of 32 bit integers!
That caused silence when trying to play a 32 bit input file on a 24
bit sound card (e.g. USB sound chips with 24 bit packed samples).

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.

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.

78e08f655a pcm_dither: renamed struct pcm_dither_24 to struct pcm_dither
There is nothing 24 bit specific in the pcm_dither_24 struct.  Since
we want to reuse the struct for 32 bit dithering, let's drop the "_24"
suffix from the struct name.
