This command allows clients to search for stickers with a specified
name.

Consume mode removes each song played

When single mode is enabled, after current song it stops playback,
or it replay same song if repeat mode is activated.

The smartstop feature is a way to tell mpd to stop playing after
current song.
This patche provides:
- 'state' command returns 'smartstop' state (1 or 0)
- 'smartstop' can activate or not the smartstop state
- when song is terminated, mpd stops playing and smartstop is set to 0

The move command now accepts a range for the first argument, in the same
form as other range commands, e.g. move 15:17 3.  The first song in the
range is placed at the destination position. Note that as with other
range commands, the range is inclusive on the left only; this example
would move only songs 15 and 16, not 17.

[mk: fixed signed/unsigned warnings; use G_MAXUINT instead of
UINT_MAX]

Clearly specified the format (song1:song2) for range argumentst, and
added the range capability of the playlistinfo command.

moveid uses an index, not a songid, for its second argument

[mk: merged memory leak patch; fixed indentation (tabs); fixed
documentation typo]

This command shuffles a range of songs.

The "sticker" command allows clients to query or manipulate the
sticker database.  This patch implements the sub-commands "get" and
"set"; more will follow soon (enumeration), as well as extended
"lsinfo" / "playlistinfo" versions.

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

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.

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.
