gio: deprecate gioscheduler, soft deprecate GSimpleAsyncResult

Browse Source 
Reimplement gioscheduler in terms of GTask, and deprecate the original
gioscheduler methods. Update docs to point people to GTask rather than
gioscheduler and GSimpleAsyncResult, but don't actually formally
deprecate GSimpleAsyncResult yet.
