Change active/inactive state spec

"active" state means "visible" on source code currently.
Specification in HMI-FW spec 0.9.2 says it's not visible.
https://wiki.automotivelinux.org/hmiframework

It's the right to have resources such as buffers(surface).
But from the view point of implementation of windowmanager-service,
it is difficult to control resources of application.
So this patch fixes just adding the methods to change
the state of client.

v2. emit active/inactive when state is changed.
