The user manual specifies "encoder", which is consistent with other
output plugins.  "encoding" should be deprecated.

A complete list which replaces the incomplete list in the mpd.conf
manpage.

Drop support for misencoded tags.  People should not be using ID3v1
anyway.

Just an attempt to prevent users from shooting themselves in the foot
by uncommenting these lines without knowing what they're doing.

2 MB was too small for cross-fading a 24 bit file.  Increasing to 4 MB
is still not too large for weak machines, but is enough for
cross-fading.

- Add mandatory "name" setting for winmm/openal examples.

- Fix the language in openal sample (a -> an)

- Added replaygain_missing_preamp and replaygain_limit settings

- Added information about "auto" replay gain mode

Additionally, update mpdconf.example to refer to mpd.conf(5) for the
complete list of tags instead of trying to repeat it.

When set, MPD will not auto-start playback on startup; it will be in
"paused" state.

Added a new optional parameter for the shout plugin called "url".

Added support for a new optional configuration setting for the httpd output
named "bind_to_address". Setting it to a specific IP address (v4 or v6) will
cause the httpd output to bind to that address exclusively. Supporting
multiple addresses in parallel is future work.

This implements the feature requests #2998 and #2646.

Limits the depth of the watched directories.  This is useful to keep
resource usage down and speed up MPD startup.

There was no setting for disabling replay gain.  It was off when the
"replaygain" setting was not there.

Both options are deprecated, and should not be used anymore.  Many
users get confused by their presence.

Add a second column of comment signs on some parameters which users
shouldn't usually set, unless they know what they're doing.

[mk: added autoconf test; fixed songlen_data_size type]

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.

The "group" configuration option is similar to "user" as it
sets user set what group MPD shall run as.  With "user"
option, MPD changed GID to the GID of the user, however,
more control could be desired.

Moreover, the patch changes the way of checking whether no
setuid(2)/setgid(2) is required -- previously user names
were compered, now UID and GIDs are compered (ie. the one we
already have (getuid(2)/getgid(2)) with the one we want to
change to).

Do all the software volume stuff inside each output thread, not in the
player thread.  This allows one software mixer per output device, and
also allows the user to configure the mixer type (hardware or
software) for each audio output.

This moves the global "mixer_type" setting into the "audio_output"
section, deprecating the "mixer_enabled" flag.

This allows you to select controls with duplicate names.

The old global settings "http_proxy_host", "http_proxy_port",
"http_proxy_user" and "http_proxy_password" continue to work.

Ths usual defaults updates, this includes clarifications, cleanups, updates
and fixes.
