685250928f gltestsrc: Use default get_caps implementation 
The custom code is wrong as it ignores the templates, which leads to
missing fields in the result. Instead, simply use the default get_caps
implementation which does it correctly (get the template, intersect
with filter and return).

f4f3284161 gl: unref display/other-context in the correct place 
Otherwise state changes from PLAYING->READY->PAUSED will cause there to
to be no display configured on the element.

03908c679e gldisplay: synchronize the searching and creation of GstGLContext's 
Ootherwise we could end up with multiple elements in different chains
each creating a context.  Fixes context creation with glvideomixer.

966cad27d7 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.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

6bb113f685 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.
