encoder: rework GstVaapiCodedBuffer and related proxy. Refactor the GstVaapiCodedBuffer APIs so that to more clearly separate public and private interfaces. Besides, the map/unmap APIs should not be exposed as is but appropriate accessors should be provided instead. * GstVaapiCodedBuffer: VA coded buffer abstraction - gst_vaapi_coded_buffer_get_size(): get coded buffer size. - gst_vaapi_coded_buffer_copy_into(): copy coded buffer into GstBuffer * GstVaapiCodedBufferPool: pool of VA coded buffer objects - gst_vaapi_coded_buffer_pool_new(): create a pool of coded buffers of the specified max size, and bound to the supplied encoder * GstVaapiCodedBufferProxy: pool-allocated VA coded buffer object proxy - gst_vaapi_coded_buffer_proxy_new_from_pool(): create coded buf from pool - gst_vaapi_coded_buffer_proxy_get_buffer(): get underlying coded buffer - gst_vaapi_coded_buffer_proxy_get_buffer_size(): get coded buffer size Rationale: more optimized transfer functions might be provided in the future, thus rendering the map/unmap mechanism obsolete or sub-optimal. https://bugzilla.gnome.org/show_bug.cgi?id=719775

encoder: fix possible memory leak of coded buffer pools. Fix gst_vaapi_encoder_reconfigure_internal() to re-/allocate the coded buffer pool only if the coded buffer size actually changed.
