This is now libvlc_track_description_list_release, as agreed at the VDD
technical discussion

This custom setting makes sure the codec actually fills the
OMX buffers with data, instead of opaque pointers to buffers
residing elsewhere.

This is needed in order to get sensible data output on
Nexus S, and most probably also on Galaxy S.

OMX_SetConfig still lacks a good way to figure out the size of
the passed struct/variable, for now hardcoded to the size of the
only use case.

The Samsung OMX components on e.g. Nexus S require major == 1
and minor == 0, otherwise they simply return errors on all
SetParameter/GetParameter calls.

Stagefright's OMX client always sets version 1.0.0, which thus
probably should be a safe choice for all android cases.

An alternative would be to store the version to set as a
variable in decoder_sys_t, and set that to 1.0.0 conditionally
only for Samsung OMX components, but that would make
OMX_INIT_COMMON more complex.
