Xen PV guest support for 8.2

Browse source 
Add Xen PV console and network support, the former of which enables the
 Xen "PV shim" to be used to support PV guests.
 
 Also clean up the block support and make it work when the user passes
 just 'drive file=IMAGE,if=xen' on the command line.
 
 Update the documentation to reflect all of these, taking the opportunity
 to simplify what it says about q35 by making unplug work for AHCI.
 
 Ignore the VCPU_SSHOTTMR_future timer flag, and advertise the 'fixed'
 per-vCPU upcall vector support, as newer upstream Xen do.
