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.

Move the responsibility for the conversion to the PCM library.  This
will allow passing the verbatim DSD samples to an output plugin.

Basic support for Direct Stream Digital.  No conversion yet, and no
decoder/output plugin support.

Resets the libsamplerate state.  Not being used yet.

(Maybe it should be "A new message is indicated...", I don't know.)

This might break older versions, I didn't test.

The main difference is that strncat takes the maximum number of
characters to copy as its third argument, while g_strlcat takes
the size of the buffer, which is how the code was using strncat.

Incomplete requests may still be constructed as a result of the
reqest buffer filling up.

size_t is unsigned most of the time, so we can't really use it to
check for negative values. Also handle strtol overflow.

An empty string is obviously not a valid integer.

Shortcut for map_directory_fs(db_get_root()).

Work around a confusing error message.

Avoid reversing the order after every update.

This was disabled when compiled with a new ffmpeg version.  Older
ffmpeg versions used it explicitly, while newer ones may pass it
through from the codec.
