For spotify playlists or tracks. Uses a spt uri, so with mpc you can
add playlists with

  mpc load spt://spotify:user:simon.kagstrom:playlist:3SUwkOe5VbVHysZcidEZtH

For Spotify tracks. Uses a spt URI, so with mpc you can play tracks
with e.g.,

  mpc add spt://spotify:track:5qENVY0YEdZ7fiuOax70x1
  mpc play

Uses the pcm_decoder_plugin for the output

Used to connect and authenticate to despotify. Provides a singleton
session and a desptoify-track-to-tags function.

E.g., spotify isn't seekable.

Otherwise the song playing might go on forever.

Should fix build errors for Win32.

Call print_playlist_result() instead of casting the enum implicitly.

Fixes build failure on WIN32.

Fix compiler warning.

Without the ogg_stream_reset() call, the "e_o_s" flag never gets
reset, and libogg writes EOS packets over and over.

This makes FreeBSD detect libogg correctly. The '==' operator is an
undocumented GNU extension to test(1) and cannot be relied upon to
exist and do the right thing. POSIX mandates string comparisons to be
done using "test foo = bar".

See code comment.

According to the Solaris dsp manpage, AFMT_S24_PACKED is
little-endian:

The Minix soundcard.h header says the same.

From http://bugs.debian.org/513291

 "In mpd.conf, the "admin" permission covers updating the db and
 killing mpd.

 "Since there are quite some usecases in which the user can upload
 music to the mpd's directory by means of anonymous FTP or so, it is
 desirable that any user may issue a db update, while killing the mpd
 should not be possible.

 "I'd suggest to remove the db update from the admin group and either
 add it to "control" or an own group."

With mono sound, jack_sample_size is smaller than frame_size (4 vs 2
bytes), and "space/jack_sample_size==0".  That means mpd_jack_play()
will return 0, although no error has occurred.

When set, MPD will not auto-start playback on startup; it will be in
"paused" state.

The client-to-client protocol was added, and that justifies increasing
the protocol version.

Version 1.0.0 of the libao library added a new field to the
ao_sample_format struct.  It is a char * named matrix.  When
an ao_sample_format is allocated on the stack, this field contains
garbage.  The proper course is to insure that is initialized to NULL.
NULL indicates that we do not want any mapping.
The struct is now initialized using a static initializer, and this
technique is compatible with all known versions of libao.

Added a new optional parameter for the shout plugin called "url".

Remove trailing whitespace found by this command:
find -name '*.[ch]' | xargs grep "[[:space:]]$"

This fixes the following valgrind warning occuring on the first call of
httpd_output_read_page:
==20124== Conditional jump or move depends on uninitialised value(s)
==20124==    at 0x425E65: httpd_output_read_page (httpd_output_plugin.c:240)
==20124==    by 0x426087: httpd_output_open (httpd_output_plugin.c:279)
==20124==    by 0x41D862: ao_open (output_plugin.h:206)
==20124==    by 0x41E133: audio_output_task (output_thread.c:590)

this needs to be done for the end of songs to be detected.
