fopen change for win32 in tag dup of vorbis
win32 adaption for head changes

using ov_test_callback with function CALLBACKS_STREAMONLY will cause
scanning to stop after the comment field.  ov_open (and ov_test)
default to CALLBACKS_DEFAULT which scans the file structure causing a
huge slowdown.  The speed improvement is huge: It scanned my files
around 10x faster This procedure has been recommended by monthy (main
vorbis developer) and was said to be safe for scanning files.

The recorder plugin writes audio played by MPD to a file.  This may be
useful for recording radio streams.

This implementation is incomplete, because support for tags is
missing, and MPD should be able to record each track to a different
file.

This option was deprecated by the 0.15 release.  This patch makes this
option invalid.

MPD checks if every flac (possibly other types as well) file contains
cuesheet on every update, which produces unneeded I/O. My music
collection is on NFS share, so it's quite noticeable. IMHO, it
shouldn't re-read unchanged files, so I wrote simple patch to fix it.

Fix stuttering due to uninitialized variable.

During the pause loop, manually sleep for 500ms if shout_delay()
returns a value greater than that.  Don't exhaust libshout's buffer.

Explicitly make the output thread leave the ao_pause() loop.  This
patch is a workaround, and the "pause" flag is not managed in a
thread-safe way, but that's good enough for now.

dirvec_delete() does not free the object, we have to call
directory_free() afterwards.

The return value of map_directory_child_fs() must be freed.

The function flac_cue_track() first calls FLAC__metadata_object_new(),
then overwrites this pointer with FLAC__metadata_get_cuesheet().  This
allocate two FLAC__StreamMetadata objects, but the first pointer is
lost, and never freed.

When you pass an empty string to directory_update_init(), it was not
freed by update_task().

Replace decoder_control.notify with decoder_control.mutex and
decoder_control.cond.  Lock the mutex on all accesses to
decoder_control.command and decoder_control.state.

For systems that cannot support fork() (like no-mmu Linux), use daemon() if
it is available for the daemonizing code.

The ID3_FRAME_GENRE field is queried only in tag_id3_import_text().
Don't pass the tag type to import_id3_string().

Splitted tag_id3_import_frame() into two specialized functions:
tag_id3_import_text() and tag_id3_import_comment().  Use
id3_frame_field() instead of directly accessing id3_frame.fields.

Changed "int type" to "enum tag_type".  Converted "int is_id3v1" to
"bool".

Prefer C over CPP.

Renamed functions.

Renamed all playlist functions to non-CamelCase.

Previously, if two identical entities appeared in one string, only the
first would get decoded. This fixes that bug.

Removed documentation about the global options mixer_type,
mixer_device and mixer_control.

The soure file client.c has nearly 1000 lines, time for splitting it
into smaller pieces to improve readability.

Prepare splitting client.c into several sources.

Added a patch to flush out the last.fm input plugin slightly. It
basically turns it into a wrapper for the appropriate plugin. Most
notably metadata is now extracted.

Instead of hard-coding the path "/etc/mpd.conf", use the configured
$(sysconfdir) path.  This can be set with:

 ./configure --sysconfdir=/etc

Note that this changes the default path to "/usr/local/etc/mpd.conf",
given the default prefix "/usr/local".  This is actually more correct
than the old default.
