Merge lp:~dandrader/unity-api/app-state-handling into lp:unity-api

[Daniel d'Andrada]

Let users of the API suspend & resume individual apps at will

API Changes:
- Removed ApplicationManagerInterface.forceDashActive
- Removed ApplicationManagerInterface.suspended
- Added ApplicationInfoInterface.requestedState

Needed for having unity8 handling the application lifecycle (suspending&resuming apps) explicitly instead of having it tied to application focus.

+ Q_PROPERTY(bool active READ active WRITE setActive NOTIFY activeChanged)
FYI: on Thursday at UOS, we had a session on desktop app lifecycle stuff. There we decided that there will be more states than running/suspended. For the desktop we will want a "throttled" state, i.e. application has throttled CPU usage.

It will be up to unity8 to have that policy, so qtmir needs to export that capability.

In that case, we would prefer a property supporting an enum: Running/Suspended/Throttled

Could you change this property to have Running/Suspended states, with a view to supporting more in future?

+ * @brief The aplication's requested state
typo. Also "state" is vague in this context, would elaborate slightly to "application's requested running state"

+ virtual void setRequestedState(RequestedState) = 0;
+ void requestedStateChanged(RequestedState value);
"const RequestedState" would do no harm, and would help compiler slightly

Looks good otherwise. Thanks for the API change

Done.

I does do some harm by making the signature longer, and the benefit of
having a "const int" parameter (as merely a hint to the reader) is
arguable in my opinion. Would like a third vote on this.

As Gerry said earlier, we are in Bikeshed land here, but as you asked for a third opinion, I'm -1 for const int and agree with Daniel here.
