Víctor Manuel Jáquez Leal 6d2f57b6c7 libs: va: add VA allocator parameter for derived images usage.
Added GstVaFeature enum type, and new parameter for VA allocator's
set_format() and get_format(). Also added a new parameter in VA pool
gst_va_pool_new_with_config() and
gst_buffer_pool_config_set_va_allocation_params().

This new parameter will define if derived images will by used for
buffer mapping.
