Fixes an assertion failure in the input_stream_seek() call.

This fixes test/run_output.

Replaces the expression [0-9]\+ by [0-9][0-9]* in autogen.sh. The
special character \+ is not POSIX compatible and thus not supported by
all sed implementations.

I've attached a patch that will make file URIs work on operating systems
that provide the getpeereid() function call to check the user ID of the
peer connected to a UNIX domain socket.

this greatly improves performance of commands that return a lot
of data, e.g. search results or recursive content of a directory,
while being connected to local mpd via tcp/ip socket.

Workaround for an assertion failure.

Rename the function to playlist_song_started(), which gets only called
if the song has actually started.

Race condition fix.

Fixes a clang warning.

libwrap support is in MPD but only for the control port.  This patch
adds support for the http port.  The code is copied from
src/client_new.c

Print those files which can be handled by a playlist plugin.

Memory leak fix.  The input_stream object passed to
playlist_list_open_stream_suffix() must be closed by the caller - this
however never happens in playlist_list_open_path(), because it does
not return it to the caller.

There is no useful return value here.

The return value of Player_LoadTitle() is allocated with malloc(), and
must be freed by the caller.

Added macros with better names: GME_BUFFER_FRAMES, GME_BUFFER_SAMPLES
(the former only used to calculate the latter).

Move into enums.

Pass sizeof(buf) to decoder_data(), not the number of samples (which
is half the size).  At the same time, pass GME_BUF_SIZE to gme_play()
- libgme really wants to get the number of samples, not the number of
stereo frames.  Previously, this plugin had been using only the first
half of the buffer.

Allocate the "tag" object after the file has been opened successfully.

Allocate the "tag" object after the file has been checked.  That
removes one tag_free() call in an error handler.

Allocate only one item on the stack.

Reuse the function tag_name_parse_i().

Reuse the function tag_name_parse_i().
