1ef5a3a200 plugins: allow bufferpool to not allocate vaapi video meta.
Add GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC params flag that
can be used to disable early allocations of vaapi video metas on buffers,
thus delagating that to the bufferpool user.

cafb25c4d1 vaapidecode: add support for VideoAlignment bufferpool option.
Always add VideoAlignment bufferpool option if the downstream element
expects its own pool to be used but does not offer it through a proper
propose_allocation() implementation for instance, and that the ALLOCATION
query does not expose the availability of the Video Meta API.

This fixes propagation of video buffer stride information to Firefox.

c2eabc17dd plugins: allow builds without GLX enabled for GStreamer 1.2.
Don't try to build GLTextureUploadMeta related code if GLX is not
enabled during GStreamer >= 1.2 builds.

6b6c10d94d plugins: request GLTextureUpload meta on buffers in the buffer pool.
Requesting the GLTextureUpload meta on buffers in the bufferpool
prevents such metas from being de-allocated when buffers are released
in the sink.

This is particulary useful in terms of performance when using the
GLTextureUploadMeta API since the GstVaapiTexture associated with
the target texture is stored in the meta.

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.

399e887c4f plugins: fix and optimize check for buffer pool allocator params.
Reset the buffer pool allocator only if the config caps changed in a
sensible way: format or resolution change. i.e. don't bother with
other caps like colorimetry et al. as this doesn't affect the way to
allocate VA surfaces or images.

f361d4a23d plugins: fix buffer pool reset_buffer() to reset memory resources.
Fix GstVaapiVideoBufferPool::reset_buffer() to reset the underlying
memory resources, and more particularly the VA surface proxy. Most
importantly, the GstVaapiVideoMeta is retained. Cached surface in
memory are released, thus triggering a new allocation the next time
we need to map the buffer.

5e18a5b1bd plugins: don't reallocate pool allocator for the same caps.
If the video buffer pool config doesn't have new caps, then it's not
necessary to reinstantiate the allocator. That could be a costly
operation as we could do some extra heavy checking in there.

c698a015a3 plugins: implement uploads from raw YUV buffers for GStreamer 1.0.
Implement GstVideoMeta::{,un}map() to support raw YUV buffer upload when
the last component is unmapped. Downloads are not supported yet. The aim
was to first support SW decoding + HW accelerated rendering (vaapisink).
e.g. for Wayland.

5b11b83321 plugins: add GstVaapiVideoMemory and GstVaapiVideoBufferPool objects.
Add initial support for GstVaapiVideoMemory backed buffer pool. The memory
object currently holds a reference to GstVaapiVideoMeta.
