Add event and state details for post-copy

Browse Source 
VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY and VIR_DOMAIN_PAUSED_POSTCOPY are
used on the source host once migration enters post-copy mode (which
means the domain gets paused on the source. After the destination host
takes over the execution of the domain, its virtual CPUs are resumed and
the domain enters VIR_DOMAIN_RUNNING_POSTCOPY state and
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event is emitted.

In case migration fails during post-copy mode and none of the hosts have
complete state of the domain, both domains will remain paused with
VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason and an upper layer may decide
what to do.
