The "lastfm" input plugin is far from complete, because MPD does not
support nesting playlists yet.  The "fluidsynth" decoder plugin
suffers from shortcomings in the libfluidsynth library:

The httpd_client_check_queue() callback function does not use its
"user_data" argument.  Don't pass any, and fix the gcc warning.

Don't append those two CFLAGS/LIBS in configure.ac.

Renamed --enable-oggvorbis-encoder to --enable-vorbis-encoder.

Use MPD_AUTO_RESULT(), and set enable_lame to "auto" by default.

Don't append LAME_CFLAGS/LAME_LIBS to MPD_CFLAGS/MPD_LIBS in
configure.ac.  Export them via AC_SUBST() instead.

Use MPD_AUTO_PKG().  Removed the checks for the Ogg Vorbis decoder
plugin, this is not directly related.

Use the new $need_encoder variable to determine whether encoder
plugins would actually be used if they were available.

Enable the HTTPD output plugin by default, provided that the encoder
API is available.

This patch makes the shout checks use MPD_AUTO_PKG() instead of
manually invoking PKG_CHECK_MODULES().  It sets the default value to
"auto" instead of "no".

$enable_encoder specifies whether one or more encoder plugins are
enabled.  This simplifies several checks, and allows easier
integration of more encoder plugins.

This command allows clients to search for stickers with a specified
name.

db_get_song was being called once for all sub-handlers, but with the
addition of the find command, we don't have a URI coming in, so doing
db_get_song once won't work anymore.

[mk: fixed initialization order]

This is a wrapper for sticker_find(), which looks up the song object.

sticker_find() finds stickers with the specified name.

Moved code from db_get_song().

Renamed directory_get_directory() to directory_lookup_directory().
Added API documentation.

Added David Guibert, Jochen Keil, Jeffrey Middleton, Sean McNamara.

On both locations, the result of write() can be ignored safely.  In
event_pipe_emit_fast(), that can only be "EAGAIN", which means that
the pipe buffer is full - no further notification required.  In
client_init(), that would be a fatal connection error, which would be
caught by the next event.

This patch fixes gcc warnings.

g_set_error() is a printf-like function, and expects a format string.
Using the return value of gai_strerror() is unsafe.

Move the declaration of "i" into the "for" loop.

The environment variable MAKE can be set by the caller process, and
may be used to pass a concurrency value (-j).
