gtask: Ensure to return 1 or 0 from getters rather than truthy ints
Since commit 290bb0dd, where various members of GTask were converted to a bitfield, some of the getters: • g_task_get_check_cancellable() • g_task_get_return_on_cancel() • g_task_get_completed() have been returning truthy ints (zero or an arbitrary non-zero integer) as boolean values, rather than the canonical boolean ints of 1 and 0.
This broke the
yield statement in Vala, whose generated C code
g_task_get_completed (…) != TRUE. i.e. Whether the
completed field has a value not equal to 1.
Fix this by explicitly converting truthy ints to canonical boolean ints in all getters.
