[MPlayer-dev-eng] [patch] removing va_arg from control functions, equalizer fix

[Jindrich Makovicka]

This patch removes all the ...'s from "control" functions in vo,vf and 
vd's. IMO passing all the parameters in the data argument would be much 
cleaner way. For equalizer control, I added the structures which allow 
passing all the parameters via a pointer. This also fixes a segfault 
when using the EQ because the parameters are passed through about four 
functions and one of them drops the all the variable arguments. With the 
variable args, the fix would require checking for the type of the 
parameters on every stage, which is extremely cumbersome and error-prone.

The patch is fairly long because it changes a lot of files, but the 
changes are only seldom longer than one line.
