v2: properly save kvm system time msr registers

Browse source 
Currently, the msrs involved in setting up pvclock are not saved over
migration and/or save/restore. This patch puts their value in special
fields in our CPUState, and deal with them using vmstate.

kvm also has to account for it, by including them in the msr list
for the ioctls.

This is a backport from qemu-kvm.git

[v2: sucessfully build without kerneldir ]
