If the UFID frame's owner is "http://musicbrainz.org", assume its
value is the MusicBrainz track id.

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.

Added a small AIFF parser library, code copied from the RIFF parser
(big-endian integers).  Look for an "ID3" chunk, and let libid3tag
parse it.

Added a small RIFF parser library.  Look for an "id3" chunk, and let

Added support for the MusicBrainz TXXX tags, documented on:

  http://musicbrainz.org/doc/MusicBrainzTag

Save some code: always allocate the tag object, and free it when it
turns out to be empty.

Don't return a writable pointer.

Read the id3 tags "TPE2" and "TSO2" into the "album artist" tag.

Pass NULL instead of &error to g_convert().  We're not interested in
the error object.

Fix for bug #1491.

We want to remove gcc.h eventually. This takes care of all the
G_LIKELY/G_UNLIKELY macros.

If a feature is disabled, don't compile the source file at all,
disable it completely in Makefile.am instead.

GLib provides an easier API for character set conversion than iconv().
Use g_convert() / g_convert_with_fallback() for all character
conversions.  We should optimize the path.h API later to return a
newly allocated buffer, so we can just pass GLib's return value.

Indentation was broken in tag_id3.c: it used 4 spaces instead of tabs.

Yet another patch which converts pointer arguments to "const".

The ID3 code uses only the public tag API, but is otherwise
unrelated.  Move it to a separate source file.

Getting rid of CamelCase; not having typedefs also allows us to
forward-declare the structures.

The usual bunch of pointer arguments which should be const.

Use "unsigned int" whenever negative values are not meaningful.  Use
size_t whenever we are going to describe buffer sizes.

Don't use CPP macros when you can use C enum... this also allows
better type checking.

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.

When dealing with in-memory lengths, the standard type "size_t" should
be used.  Missing one can be quite dangerous, because an attacker
could provoke an integer under-/overflow, which may provide an attack
vector.

Local variables which are never read before the first assignment don't
need initialization.  Saves a few bytes of text.  Also don't reset
variables which are never read until function return.

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.

thread-safety work in preparation for rewrite to use pthreads

Expect no regressions against trunk (r7078), possibly minor
performance improvements in update (due to fewer heap
allocations), but increased stack usage.

Applied the following patches:

* maxpath_str for reentrancy (temporary fix, reverted)
* path: start working on thread-safe variants of these methods
* Re-entrancy work on path/character-set conversions
* directory.c: exploreDirectory() use reentrant functions here
* directory/update: more use of reentrant functions + cleanups
* string_toupper: a strdup-less version of strDupToUpper
* get_song_url: a static-variable-free version of getSongUrl()
* Use reentrant/thread-safe get_song_url everywhere
* replace rmp2amp with the reentrant version, rmp2amp_r
* Get rid of the non-reentrant/non-thread-safe rpp2app, too.
* buffer2array: assert strdup() returns a usable value in unit tests
* replace utf8ToFsCharset and fsCharsetToUtf8 with thread-safe variants
* fix storing playlists w/o absolute paths
* parent_path(), a reentrant version of parentPath()
* parentPath => parent_path for reentrancy and thread-safety
* allow "make test" to automatically run embedded unit tests
* remove convStrDup() and maxpath_str()
* use MPD_PATH_MAX everywhere instead of MAXPATHLEN
* path: get rid of appendSlash, pfx_path and just use pfx_dir
* get_song_url: fix the ability to play songs in the top-level music_directory
