206638c439 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.

85834d6bbc glcontext: add specific error message when missing GL_SHADING_LANGUAGE_VERSION 
GL_SHADING_LANGUAGE_VERSION was introduced since ES 2.0, but in some
android emulator doesn't support this feature. To prevent confusion for
developer, the error message need to be more clear.

40d2693d07 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

be9ad5eeb2 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.

1a98face84 gl: win32: do not call SetParent in release_parent_win_id() 
When called from gst_gl_window_win32_close(), internal window
could not exist, and if it does it's going to be destroyed just
after that anyway. Also it causes window_proc() to be called
and crash because it gets a NULL context.

When called from gst_gl_window_win32_set_window_handle() we are
going to set another parent anyway, and it's probably better to
reparent directly instead of passing by a NULL parent which could
cause the internal window to popup briefly.

247697ce62 gl: win32: fix crash when finalizing GstGLContext 
gst_gl_context_finalize() is calling gst_gl_window_win32_quit()
which was posting a message. But then window_proc takes window's
context and get a NULL.

Now that we've got a GMainLoop we can do like other backends and
simply call g_main_loop_quit().

This also remove duplicated code to release the parent window and
potential crash there because parent_proc could be NULL if we never
created the internal window. That could happen for example if setting
state to READY then setting a window_handle, and go back to NULL state.

e24bc348bd gl: win32: use a GMainContext to dispatch win32 messages

x11 and wayland backends both create a custom GSource for this,
so there is no reason to not do that for win32.
