da8b01771f playlist/soundcloud: libyajl2 uses size_t for string lengths

725fbe946b output/alsa: split the frame_size attribute 
Make it in_frame_size and out_frame_size, to account for packing.

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.

5b61e077e0 pcm_export: add option "pack" 
Converts padded 24 bit samples to packed 24 bit samples.  Will replace
the packed S24 sample format, which is not used internally.

921cc3e5db output/oss: remember the real OSS format

initially.

55708b39c3 audio_format: DSD_OVER_USB is padded to 32 bit 
For simplicity, pad the dCS samples to 32 bit.  Packed 24 bit samples
are rarely used.  This patch does not include a real code change,
because there is no user of DSD_OVER_USB yet.

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).

7cef52478d A soundcloud playlist plugin. 
Requires YAJL to build, and this doesn't include the necessary
automake changes. Can be built using
./configure CFLAGS="-I/usr/include/yajl" LIBS="-lyajl" --enable-soundcloud

Add the following to your config:

playlist_plugin {
        name "soundcloud"
        enabled "true"
        apikey "c4c979fd6f241b5b30431d722af212e8"
}

Then you can stream from soundcloud using calls like:

mpc load soundcloud://track/<track-id>
mpc load soundcloud://playlist/<playlist-id>
mpc load soundcloud://url/http://soundcloud.com/some/track/or/playlist

For the last case, you can leave off the http:// or
http://soundcloud.com/ .

c551c8b31b raop_output: fix raop_session inbalance 
raop_session_free must be called from raop_output_finish,
not from raop_output_remove.
In raop_output_remove, do close the ntp_server & control port.
