Start the daemon after --create-db.  This makes --create-db a flag
which discards the old database and starts with a fresh one.

There is no reason to use the shortcut "mix" instead of "mixer".

Allow logging to syslog if log_file is configured to "syslog".

Removed the "error_file" option.  There is only one log file now.  If
a user wants to see only the errors, he should configure a log_level.

Fix a few problems with the huge mpdconf update. There's alot of shift here, mostly due to word wraps. This, also, improves on uniformity and clarity of the document.

"playlistdelete" takes a song position, not a song id.  There are
no song ids in stored playlists.

Over time mpdconf has evolved and has been maintained and contributed to by many different folks at different
times. Try to give it some unity. Attempt to clear up some language and make things crystal clear. Add more
examples. Use tabs when it makes sense. Make better borders. Remove obsolete options. Try to put more defaults
when it makes sense.

The "user" option does not work if MPD is started by an unprivileged
user.

Additionally, add an example in mpdconf.example.

MPD 0.13 and older followed all symbolic links.  Although this can be
a security problem (as it has always been), 0.14 should offer the same
default behaviour as 0.13.

The configuration options "follow_outside_symlinks" and
"follow_inside_symlinks" let the user control whether MPD should
follow symbolic links in the music directory.

[mk: converted variables to "bool"; moved configuration to
update_global_init()]

Added $(DOCBOOK_FILES) to $(EXTRA_DIST).  Don't include the generated
protocol.html in the tarball.

Over the years, a lot of commands have been added to MPD which were
documented only in the wiki
(http://mpd.wikia.com/wiki/Protocol_Reference).  Merge all missing
commands from there.

Correct lots of grammar and spelling errors.  Unify some phrases.

Wrapped keywords in DocBook tags where appropriate.

Generate and install protocol.html if xmlto is available.

The attribute value must be lower case: <arg rep="repeat">

The goal is to have one structured document which is the authoritative
protocol specification.  The documentation which currently resides in
the wiki will be merged.

Send last modification timestamps to the client.  This allows the
client to see when another client modifies a stored playlist.

"listplaylists" returns a list of all stored playlists.  This command
seems more elaborate than listing them below "lsinfo".

When building with the ancient automake 1.6 version, the following
errors occur:

 Makefile.am:5: invalid variable `doc_DATA'
 doc/Makefile.am:2: invalid variable `doc_DATA'

This patches renames some internal variables.

The manual page suggests that you can specify multiple servers, but it
did not clarify what that means.

"idle" waits until something noteworthy happens on the server,
e.g. song change, playlist modified, database updated.  This allows
clients to keep up to date without polling.

Makefile.am sets docdir = $(prefix)/share/doc/$(PACKAGE). This
overrides the setting specified in ./configure --docdir.

Added mpd.conf options for disabling automatic resamling, sample
format and channel conversion.  This way, users may choose to override
ALSA's automatic resampling, and use libsamplerate instead.

A ".TP" was missing, and broke the manual page's layout.

Added configuration parameter "protocol" which lets the user choose
from 3 shout protocols.  This adds support for real shoutcast servers.

* spaces => tabs
* long lines wrapped
* trailing whitespace killed

I've perhaps gone a bit overboard, but here's the current rundown:

Both Ogg and MP3 use the "shout" audio output plugin.  The shout audio
output plugin itself has two new plugins, one for the Ogg encoder,
and another for the MP3 (LAME) encoder.

Configuration for an Ogg stream doesn't change.  For an MP3 stream,
configuration is the same as Ogg, with two exceptions.  First, you must
specify the optional "encoding" parameter, which should be set to "mp3".
See mpd.conf(5) for more details.  Second, the "quality" parameter is
reversed for LAME, such that 1 is high quality for LAME, whereas 10 is
high quality for Ogg.

I've decomposed the code so that all libshout related operations
are done in audioOutput_shout.c, all Ogg specific functions are in
audioOutput_shout_ogg.c, and of course then all LAME specific functions
are handled in audioOutput_shout_mp3.c.

To develop encoder plugins for the shout audio output plugin, I basically
just mimicked the plugin system used for audio outputs.  This might be
overkill, but hopefully if anyone ever wants to support some other sort
of stream, like maybe AAC, FLAC, or WMA (hey it could happen), they will
hopefully be all set.

The Ogg encoder is slightly less optimal under this configuration.
It used to send shout data directly out of its ogg_page structures.  Now,
in the interest of encapsulation, it copies the data from its ogg_page
structures into a buffer provided by the shout audio output plugin (see
audioOutput_shout_ogg.c, line 77.)  I suspect the performance impact
is negligible.

As for metadata, I'm pretty sure they'll both work.  I wrote up a test
scaffold that would create a fake tag, and tell the plugin to send it
out to the stream every few seconds.  It seemed to work fine.  Of course,
if something does break, I'll be glad to fix it.

Lastly, I've renamed lots of things into snake_case, in keeping with
normalperson's wishes in that regard.

[mk: moved the MP3 patch after this one.  Splitted this patch into
several parts; the others were already applied before this one.  Fixed
a bunch GCC warnings and wrong whitespace modifications.  Made it
compile with mpd-mk by adapting to its prototypes]

except that it now uses a timer for throttling.
