Add a "vnet_state" field to struct vnet.

This is set to the SI_SUB_* value before executing any VNET_SYSINIT
or VNET_SYSUNINT.  While good for debugging especially VNET teardown
problems having a chance to know at which level during teardown we are,
it will also be used to identify to detcted a "stable state"
(as in fully up and running) later on.
