shell: Introduce workspace manager interface

Browse source 
The workspace manager interface purpose is to provide clients with
control and knowledge about the current workspace state. Initially only
one function and one event exists; moving a surface and state updated
event. A workspace is represented as an index in a 1 dimensional array.

A client keeps track of the state by being broadcasted events when the
state changes, currently limited to current workspace or number of
workspaces available.

A client can send an asynchronous request to the manager asking to move
a surface to workspace identified by an index. It is up to the shell to
actually move it.
