Start MountService before performBootDexOpt

This change is to start Mountservice before starting
performBootDexOpt, as in one case, in performBootDexOpt
when system upgrade happens, StorageManager will be started to
get the low threshold of DataDir. But, at this point, as
Mountservice is still not up, StorageManager will end up
having a null object of Mountservice.

Recents: Port "Development shortcut" (2/2)

This patch includes the equivalent of our Development Shortcuts in
CM11 recents. Recents is very different now and this is mostly a rewrite.

The semantics changed a bit as well. The current code already has special
developer behavior when long-pressing the app icon and that is also where
the developer shortcuts are hooked. If the app icon is long-pressed and
developer shortcuts are active, a menu will be shown with the several available
options.

Fixes CML-61
