Log:
Support select subtitle by source, add 4 properties:
1. sub_source for current sub source (sub file, vobsub, or from demuxer).
2. sub_file for all subtitles from files.
3. sub_vobsub for all subtitles from vobsub.
4. sub_demux for all subtitles from demuxer.
Now mplayer can supply a stable and clear interface to external programs
using mplayer in slave mode to select a subtitle by its source and
its unique id for that source printed by mplayer using -identify parameter.

     Cycle through the available subtitles if [value] is omitted or less
     than -1. Supported subtitle sources are -sub options on the command
     line, VOBsubs, DVD subtitles, and Ogg and Matroska text streams.
+    This command is mainly for cycling all subtitles, if you want to set
+    a specific subtitle, use sub_file, sub_vob, or sub_demux.
+
+sub_source [source]
+    Display first subtitle from [source]. Here [source] is an integer:
+    SUB_SOURCE_SUBS   (0) for file subs
+    SUB_SOURCE_VOBSUB (1) for VOBsub files
+    SUB_SOURCE_DEMUX  (2) for subtitle embedded in the media file or DVD subs.
+    If [source] is -1, will turn off subtitle display. If [source] less than -1,
+    will cycle between the first subtitle of each currently available sources.
+
+sub_file [value]
+    Display subtitle specifid by [value] for file subs. The [value] is
+    corresponding to ID_FILE_SUB_ID values reported by '-identify'.
+    If [value] is -1, will turn off subtitle display. If [value] less than -1,
+    will cycle all file subs.

+sub_vob [value]
+    Display subtitle specifid by [value] for vobsubs. The [value] is
+    corresponding to ID_VOBSUB_ID values reported by '-identify'.
+    If [value] is -1, will turn off subtitle display. If [value] less than -1,
+    will cycle all vobsubs.
+
+sub_demux [value]
+    Display subtitle specifid by [value] for subtitles from DVD or embedded
+    in media file. The [value] is corresponding to ID_SUBTITLE_ID values
+    reported by '-identify'. If [value] is -1, will turn off subtitle display.
+    If [value] less than -1, will cycle all DVD subs or embedded subs.
