b1bbc087c1 encoder: avoid GstVaapiCodedBuffer redefinition
The symbol GstVaapiCodedBuffer is already defined in
gst-libs/gst/vaapi/gstvaapicodedbuffer.h which is loaded, at the end, by
gstvaapiencoder_objects.h. Clang complains about the symbol re-definition.

This patch removes that redefinition.

786b68ac21 encoder: add infrastructure for per-slice handling of packed headers.
The packed slice header and packed raw data need to be paired with
the submission of VAEncSliceHeaderParameterBuffer. So handle them
on a per-slice basis insted of a per-picture basis.

[removed useless initializer]

d45c6a486f encoder: clean-up objects.
Various clean-ups to improve consistency and readability: rename some
variables, drop unused macro definitions, drop initialization of vars
that are zero-initialized from the base class, drop un-necessary casts,
allocate GPtrArrays with a destroy function.

0fb7c60508 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.

30f382fcdf vaapiencode: optimize _handle_frame() to avoid extra allocation.
Optimize gst_vaapiencode_handle_frame() to avoid extra memory allocation,
and in particular the GstVaapiEncObjUserData object. i.e. directly use
the VA surface proxy from the source buffer. This also makes the user
data attached to the GstVideoCodecFrame more consistent between both
the decoder and encoder plug-in elements.

8174a35737 Add initial infrastructure for video encoding.
Add initial API for video encoding: only basic interfaces and small
encoder objects are implemented so far.
