[MPlayer-dev-eng] [PATCH] Chapter support improvement

[Ulion]

Hello,

I recent found chapter in mkv is really a good design, certainly dvd
also support it. But for mplayer, its chapter support is not good
enough, then I wrote several patches to improve it.

First patch adds 3 functions for demuxer to get chapter infos:

+/// Get current chapter index if available.
+int demuxer_get_current_chapter(demuxer_t *demuxer);
+/// Get chapter name by index.
+char *demuxer_chapter_name(demuxer_t *demuxer, int chapter);
+/// Get total chapter number.
+int demuxer_chapter_count(demuxer_t *demuxer);

Second patch make chapter become a mplayer property, now we can
get/set/print/step up/step down on the chapter property.

Third patch add chapter support for libmenu, it bases on Benjanmin's
menu_chapsel.c patch, but using functions from my first patch.
