Don't free the string right after calling log_init_file().  Add a new
function log_deinit() that frees the string on shutdown.

This fixes cycling the log file after SIGHUP (Mantis ticket 0003524).

Eliminate the g_usleep() call.

Reduce command latency while paused.

One large loop and only one pa_stream_get_state() call.

Reset the timer when paused and no client is connected.

This fixes Mantis ticket 0003527.

This is part of libavutil.

Additionally, update mpdconf.example to refer to mpd.conf(5) for the
complete list of tags instead of trying to repeat it.

Duplicate the music_dir variable: one encoded in UTF-8, and another
one using the configured filesystem character set.  This fixes an
ancient MPD bug.

MPD requires GLib 2.16.

That function is not pure, it writes to error.

When marked as pure, the compiler is allowed to assume it does not do
anything to error, so it can remain NULL, which would result in an
invalid read in print_error().

Rewrite of the pc_get_error_message() function, now using a GError
object instead of the complicated "errored_song" attribute.

Eliminates explicit global initialisation.

The new block overrides the "db_file" setting, and allows configuring
any database plugin.

No more hard-coded "simple" plugin.

Let the caller take care for legacy conversion.

Preparing for non-"simple" database plugins.

Useless call.

Fixes assertion failures in the Directory library.
