39dda15f5f codec: add helper macros to maintain object refcount.
Add gst_vaapi_mini_object_{ref,unref,replace}() helper macros so that
to avoid explicit casts to GstVaapiMiniObject in all caller sites.

15519ebe3d legal: add per-file authorship information.
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.

3cc7b26961 libs: use GstVaapiMiniObject for video decoders.
Port GstVaapiDecoder and GstVaapiDecoder{MPEG2,MPEG4,JPEG,H264,VC1} to
GstVaapiMiniObject. Add gst_vaapi_decoder_set_codec_state_changed_func()
helper function to let the user add a callback to a function triggered
whenever the codec state (e.g. caps) changes.

6439169db5 libs: refine GstVaapiMiniObject.
Drop support for user-defined data since this capability was not used
so far and GstVaapiMiniObject represents the smallest reference counted
object type. Add missing GST_VAAPI_MINI_OBJECT_CLASS() helper macro.

Besides, since GstVaapiMiniObject is a libgstvaapi internal object, it
is also possible to further simplify the layout of the object. i.e. merge
GstVaapiMiniObjectBase into GstVaapiMiniObject.

c727e5b6d6 decoder: drop useless checks for codec objects.
Codec objects are used internally only and they are bound to be created
with a valid GstVaapiDecoder object.

195a61fa02 decoder: allow pictures to be cloned for field decoding.
Add gst_vaapi_picture_new_field() function that clones a picture, while
preserving the parent picture surface. i.e. the surface proxy reference
count is increased and other fields copied as is. Besides, the picture
is reset into a "non-output" mode.

a79c7f9fa6 decoder: optimize slice data buffers initialization.
VA drivers may have a faster means to transfer user buffers to GPU
buffers than using memcpy(). In particular, on Intel Gen graphics, we
can use pwrite(). This provides for faster upload of bitstream and can
help higher bitrates.

vaapi_create_buffer() helper function was also updated to allow for
un-mapped buffers and pre-initialized data for buffers.

e5d12e8853 decoder: rework the internal VA objects API.
The new API simplifies a lot reference counting and makes it more
flexible for future additions/changes. The GstVaapiCodecInfo is
also gone. Rather, new helper macros are provided to allocate
picture, slice and quantization matrix parameter buffers.
