c06715bde6 glupload/download/convert: provide transform_caps functions
Allows finer grain decisions about formats and features at each
stage of the pipeline.
Also provide propose_allocation for glupload besed on the supported
methods.

5f547c5600 gl: initial support for texture targets other than GL_TEXTURE_2D
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

NULL uploaded buffers.

d5c3693791 gl: split glcolorconvert usage from glupload
the separation allows the transfer operation to occur in a separate
thread/time which may increase performance in specific circumstances.

f2af65ee2d gl: add a sync meta for synchronizing across GL contexts
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.

9d8055186d videoaggregator: Expose vmethods to set converters and prepare/clean frames
This gives more flexibility to the subclasses and permits to remove the
GstVideoAggregatorClass->disable_frame_conversion ugly API.

WARNING: This breaks the API as it removes the disable_frame_conversion
field

API:
  + GstVideoAggregatorClass->find_best_format
  + GstVideoAggregatorPadClass->set_format
  + GstVideoAggregatorPadClass->prepare_frame
  + GstVideoAggregatorPadClass->clean_frame

  - GstVideoAggregatorClass->disable_frame_conversion

Otherwise, it is only possible for the sink pads and the src pads to

5b8d7a443e glupload: provide the output buffer that is rendered into
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.

30ddb384ab glmixer: unref the GstGLUpload in the pad if freed while running
Dynamic pipelines that get and release the sink pads will finalize
the pad without going through gst_gl_mixer_stop() which is where the
upload object is usually freed.  Don't leak objects in such case.
