The change upgrades the driver to use the split Communication Status
Block (CSB) format. In this way the variables written by the guest
and read by the host are allocated in a different cacheline than
the variables written by the host and read by the guest; this is
needed to avoid cache thrashing.

- use PCI_VENDOR and PCI_DEVICE ids from a publicly allocated range
(thanks to RedHat)
- export memory pool information through PCI registers
- improve mechanism for configuring passthrough on different hypervisors
Code is from Vincenzo Maffione as a follow up to his GSOC work.
fix build on 32 bit platforms
simplify logic in netmap_virt.h
The commands (in net/netmap.h) to configure communication with the
hypervisor may be revised soon.
At the moment they are unused so this will not be a change of API.
