Cache wayland globals

Store the wayland registry globals in a list so that we can bind to them from a
user/test program. When a custom interface (protocol extension) is used in a
wayland compositor, this allows user/test program to use that interface. For
instance, one might provide a custom wayland test protocol that give access to
otherwise hidden/missing functionality that allows effective automated testing
(in wayland engines). See the Weston unit test suite for an example of this
concept.
