UI: supports reboot from context menu

When a malfunction of emulator occurs, such as no response from the guest OS,
what a developer can do is selecting "force close"
and restarting from emulator manager.

In order to avoid the inconvenience of doing it, reboot menu is added.
It is working directly to hardware after requesting sync() to guest OS

         ----------------
         | Context menu |
         ----------------
         |   reboot     |
         ----------------                         ----------
                |                                 | emuld  |
     ------------------------                     ----------
     | 1. send sync message |   ------------->    | sync() |
     | 2. start a timer     |                     ----------
     ------------------------
               | The timer expires after 1s
   -------------------------------
   | qemu_system_reset_request() |
