[spice-gtk v1 6/6] RFC: test: session: gstreamer init by us or client

[Victor Toso <victortoso@xxxxxxxxxx>]

From: Victor Toso <me@xxxxxxxxxxxxxx>

Does not work properly just because gst_is_initialized() checks if
gst_init() or gst_check_init() was ever called but it does not
consider if gst_deinit() was called too. I'm sending this RFC to check
if should be added or wait till feedback on upstream about the API,
that is, I have a downstream patch that gst_is_initialized() would
return FALSE if gst_deinit() was called ...
