Qemu support for multiple keyboard devices

v6 (Dmitry Zhurikhin <[email protected]>):
- merge with commit 57aa265d462a64a06268be26d49020729cff56c1
- moved changes from usb-hid.c and qemu_activate_keyboard_event_handler function to the first patch as more appropriate
- changed some keyboard names to be more consistent
- added 'info keyboard' to the 'info subcommand' documentation chapter
- fixed an 'avoid assignment of zero to static variable' warning by 'scripts/checkpatch.pl'

Qemu support for multiple keyboard devices:
Patch #1
Adding keyboard is done to the queue instead of "last added keyboard wins", when removing keyboard via device_del - previous keyboard is selected.

Patch #2
Adding 2 new monitor commands to handle keyboard list:
'info keyboard' - show all keyboard devices and mark the current one 'keyboard_set' - set active keyboard by index as displayed by 'info keyboard'
