Add the VMS_RESTART variant of vmstate, for use when upgrading qemu in place
on the same host without a reboot. Invoke it using:
cprsave <filename> restart
VMS_RESTART supports guest ram mapped by private anonymous memory, versus
VMS_REBOOT which requires that guest ram be mapped by persistent shared
memory. Subsequent patches complete its implementation.

This should be a modification to an enum type (the 'CprMode' type I
suggested earlier in the series).
