14c28415b9 va: Remove gst_va_decoder_destroy_buffers()
Since GstVaDecodePicture is destroyed completely with its free() function and
it's used as destroy notify by codecs picture, there's no need to call
gst_va_decoder_destroy_buffers() externally, since the codecs base classes
destroy the codec picture when it's required.

f5c7ada98e va: Destroy picture unreleased buffers when finalize.
The current way of GstVaDecodePicture's finalize will leak some
resource such as parameter buffers and slice data.
The current way deliberately leaves these resource releasing logic
to va decoder related function and trigger a warning if we free the
GstVaDecodePicture without releasing these resources.
But in practice, sometimes, you do not have the chance to release
these resource before picture is freed. For example, H264/Mpeg2
support multi slice NALs/Packets for one frame. It is possible that
we already succeed to parse and generate the first several slices
data by _decode_slice(), but then we get a wrong slice NAL/packet
and fail to parse it. We decide to discard the whole frame in the
decoder's base class, it just free the current picture and does not
trigger sub class's function again. In this kind of cases, we do
not have the chance to cleanup the resource, and the resource will
be leaked.

2950c76c8f va: Add HEVC decoding support
This add HEVC decoding support into the new VA plugin. This implementation has
been tested using the ITU comformance test (through fluster). It fails all
MAIN10 tests, as this is not implemented yet along with the following:

CONFWIN_A_Sony_1 (looks fine, but md5sum is incorrect)
PICSIZE_A_Bossen_1 (height too high)
PICSIZE_B_Bossen_1 (same)
VPSSPSPPS_A_MainConcept_1 (parser issue)
