Pushes cancellable onto the cancellable stack. The current
cancellable can then be received using g_cancellable_get_current().
This is useful when implementing cancellable operations in
code that does not allow you to pass down the cancellable object.
This is typically called automatically by e.g. GFile operations,
so you rarely have to call this yourself.
