Marek Marczykowski f447a458f2 dom0+vm: Update VM kernel mechanism (#242)
Get kernel from global kernels dir (/var/lib/qubes/vm-kernels), not per-VM. Can
be configured by qvm-prefs (kernel parameter).
New tool: qvm-set-default-kernel

For backward compatibility kernel=None means kernel in VM dir (kernels subdir).
(possibly empty) modules.img should be created in it.
