Gwenole Beauchesne 0a108653f2 texture: add support for cropping rectangle during transfer.
The gst_vaapi_texture_put_surface() function is missing a crop_rect
argument that would be used during transfer for cropping the source
surface to the desired dimensions.

Note: from a user point-of-view, he should create the GstVaapiTexture
object with the cropped size. That's the default behaviour in software
decoding pipelines that we need to cope with.

This is an API/ABI change, and SONAME version needs to be bumped.
