Update a keyboard state from a set of explicit masks.
This entry point is intended for window systems and the like, where a
master process holds an xkb_state, then serializes it over a wire
protocol, and clients then use the serialization to feed in to their own
xkb_state.
All parameters must always be passed, or the resulting state may be
incoherent.
The serialization is lossy and will not survive round trips; it must only
be used to feed slave state objects, and must not be used to update the
master state.
If you do not fit the description above, you should use
xkb_state_update_key() instead. The two functions should not generally be
used together.
@returns A mask of state components that have changed as a result of
the update. If nothing in the state has changed, returns 0.
