[MPlayer-dev-eng] [PATCH] make ID_LENGTH float instead of int

[Oded Shimon]

This patch makes mplayer -identify show accurate ID_LENGTH in float instead 
of int. Works for me, I only tested a few demuxers. Any objections? I'll 
commit tommorrow.

BTW, could someone tell me why we have the slave command 'get_time_length'? 
It's identical to -identify's ID_LENGTH, and IMO is also more appropiatte 
there than a slave command.
