d45e0f807f glbasefilter: only call gl_{stop,start} if the context changed 
Removes the redundant GL object creation/deletion on every
decide_allocation call which is being called for every caps change.

Thus reduces the required GL state changes on reconfigure events
which are being sent by glimagesink/xvimagesink

edd3c007ea glupload: Recalculate offset and size in raw upload 
As we only expose the mapped portion of the frame into the GL
memory object (and not the original padding) we need to
re-calculate the size and offset.

a342d95ca6 glsink: Enable sync meta on pools we offer 
As the upload is asynchronous, we need to enable the sync meta to
gain correct rendering. The buffer pool receiver don't know about
that.

f3bd3d0b94 gl: Add opengl_version.h to the list of sources 
Adding this private header to the list of sources. We don't want to make
this header public, but we need it in the list of sources otherwise it
won't be included in the tarball. This fixes make distcheck.

This regression was introduced by commit 1a6fe3db

d576a71e9a gloverlaycompositor: Add shader to convert BGRA/ARGB -> RGBA 
Depending on the bytes order we will get BGRA (little) and ARGB (big)
from the composition overlay buffer while our GL code expects RGBA. Add
a fragment shader that do this conversion.

260104e485 glupload: Remove debug output from gst_gl_upload_transform_caps() 
We can't know if the GstGLUpload type is initialized at this point already,
and thus our debug category might not be initialized yet... and cause an
assertion here.

As we don't print debug output for any of the other transform functions, let's
defer this problem for now.

78957c45c2 glcontext: track sharedness with a cookie 
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.
