framework: Add advanced reboot options (2 of 2)

This commit is an squash of the commits below and re-adds the reboot
logic to CM.

I took the liberty to rewrite some of the ShutdownThread code because
it had some lingering issues present since I originally wrote this
for CM7 (!!). Namely, the reboot reason was being changed when the items
are pressed instead of when the user presses the positive button. This
made some people add workarounds like handling back button presses and
whatnot, these are gone now.
