I don´t disagree with this specific patch (unlike the following one). Useless 
parameters can and should be removed. My point was that this is only the tip 
of the iceberg.

In the long run, vlc_va_t.extract() should be superseded by opaque-to-RAM 
video format conversion plugins, and then removed. In turn, that imples the 
removal of vlc_va_t.release() in favor or picture_Release() - since the 
conversion plugins would not have access to vlc_va_t.release().
