EDL enhancement/fixes:

Browse Source 
*Some edl's code moved from mplayer.c to edl.c (mencoder will use the
same functions)
* slighty faster
* removed MAX_EDL_ENTRIES limit (just reserve the memory we really need)
* really treat edl_records as a linked list (coz it is)
* edl now 'remembers' pending operations after a manual _seek_
* better way of handling Mute/Umute eliminates some nasty bugs
when manual seeking (scrwed up mute/unmute order, no audio after
seek, etc)
* seeking while on -edl mode now _WORKS_
