Fix clang warning.

Use audio_format_mask_valid() to verify a mask.

Thanks to clang for complaining.

Otherwise OGGs can't be played.

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.

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.

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.

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 0x41E133: audio_output_task (output_thread.c:590)

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

When the configure options were moved around for 0.16, the order was
changed, and the Tremor check broke.

<stdbool.h> needs to be included unconditionally from definition of
NDEBUG, since »bool« doesn't get defined otherwise.

A bit of automake magic (see info automake "Per-Object Flags").
Compile-tested.

When a music_chunk to be crossfaded consists only of a tag,
cross-fading is not possible, and led to an assertion failure.  This
patch just discards those, as if cross-fading was not enabled.

During the whole output thread, the audio_output object is locked, and
it is only unlocked while waiting for the GCond and while running a
plugin method.  The error handler in ao_play_chunk() attempted to lock
the object again, which was code from MPD 0.15.x which should have
been removed a long time ago.

Until the decoder plugin has called decoder_initialized(), the player
may not submit seek commands.  This however could occur with a slow
decoder and a CUE file with a virtual song offset.  This patch adds
another check.
