The "tagtypes" command now has several sub commands which can be used
to edit that mask.

Add one method that prints only the tag values, but not the song
duration.

Enables using range-based "for".

Detach the Song class completely from the public API, only to be used
by SimpleDatabase and the update thread.

Don't create a temporary Song object in handle_lsinfo().  Instead,
print all tags while parsing the remote file.

Move to TagSettings.c and use C99 initializers.

After we've been hit by Large File Support problems several times in
the past week (which only occur on 32 bit platforms, which I don't
have), this is yet another attempt to fix the issue.

This updates the copyright header to all be the same, which is
pretty much an update of where to mail request for a copy of the GPL
and the years of the MPD project. This also puts all committers under
'The Music Player Project' umbrella. These entries should go
individually in the AUTHORS file, for consistancy.

Renamed functions and variables.

Renamed numOfItems to num_items.

Don't pass the raw file descriptor around.  This migration patch is
rather large, because all of the sources have inter dependencies - we
have to change all of them at the same time.

Move everything which dumps a tag to a file descriptor to tag_print.c.
This relaxes dependencies and splits the code into smaller parts.

Make the code more readable by hiding big formulas in an inline
function with a nice name.

We want to expose the AudioFormat structure to plugins; remove some
clutter by moving its declaration to a separate header file.

Try to only include headers which are really needed.  We should
particularly check all "headers including other headers".  The
long-term goal is to have a manageable, small API for plugins
(decoders, output) without so many mpd internals cluttering the
namespace.

This will make refactoring features easier, especially now that
pthreads support and larger refactorings are on the horizon.

Hopefully, this will make porting to other platforms (even
non-UNIX-like ones for masochists) easier, too.

os_compat.h will house all the #includes for system headers
considered to be the "core" of MPD.  Headers for optional
features will be left to individual source files.
