c0cb6eacb5 gluploadelement: fix leak of upload library object
When only linking the element, the upload object will be created from
_transform_caps() but will never be unreffed as the only case is in _stop().

Add an unref if non-NULL to a new finalize handler for this case.

acd33a240f glupload: create the GstGLUpload object in ::transform_caps
Previously it was created in the init function and destroyed in ::stop, which
lead to segfaults when reusing the element.

Now the upload object is created in ::transform_caps if it is NULL, which is the
earliest we need it. The other vfuncs already bail out if the upload object is
NULL, which means that negotiation wasn't done.

cc9f65f191 gstglupload: make the GLMemoryUpload method output the correct texture-target
Now when used with video/x-raw as input, the GLMemoryUpload method checks for
->tex_target in input GLMemory(es) and sets the output texture-target
accordingly.

Fixes video corruption with a pipeline like avfvideosrc ! video/x-raw !
glimagesink where on macos avfvideosrc pushes RECTANGLE textures but glupload
was configuring texture-target=2D as output.

73bad9e856 glupload: remove useless release_buffer
It's a leftover from when we weren't outputting GstBuffer's and
returning raw texture id's.

5efb855edd glupload: Use base class metadata copy function
This allow properly copying selected meta, like the composition
overlay. Note that output buffer need to be readable, but GlUpload
keeps a ref. For now, simply drop GlUpload ref after perform,
leaving that ref has no purpose. The method shall be removed
in the future.

d1cece731e gl: Let base transform relay the meta api for us
During allocation query, when this element is not passthrough, it must
relay the overlay compostion meta and it's parameters. Fortunatly, base
transform can do this for us.

4cf2d84315 glupload: Forward composition meta even without params
When the sink does not know the window size (e.g not created yet)
it will not add any param to the the composition meta. This is no
reason not to forward this meta API. Fixes issue where it could not
attach until we resize the window.

052b0a1caf glimagesinkbin: Add allocation query for GstVideoOverlayComposition
Adds an GST_VIDEO_OVERLAY_COMPOSITION_META_API_TYPE query to glupload
and glimagesink.  Detects the query from the downstream elements, so
it is executed only when downstream supports the overlay API.

This makes pipelines with textoverlay ! glupload ! gldownload ! xvimagesink possible.
Uses allocation meta struct for passing the window size upstream.

5f38bcf905 uploadelement: Protect against NULL pointer
I notice that if you stop the pipeline during a renegotiation
the upload may be NULL while an allocation query is being run.
In that scenario, returning FALSE to the allocation query is the
best thing.

55dbb25dcc glupload: move meta-data copy into gst-gl library
In some upload implementations the out buffer has more than one references,
turning the buffer not writable, so it won't be possible to modify its
meta-data.

This patch moves the meta-data copy before increasing the reference of the out
buffer.
