GIC-500 implementation, software + KVM

This is a complete GICv3 implementation, both software emulation and KVM acceleration are supported.

This series is a consolidated and updated patch set, based on:
- GIC-500 implementation:
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg01512.html
- vGICv3 implementation:
https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg04496.html
I decided to repost because qemu development has progressed and it became difficult to apply those series to current master.

Changes from previous versions:
- Removed RFC prefix
- Base class separated from the rest, as was requested in RFC v2 review
- Fixed small number of broken comments / code formatting issues, according to the same review
- Removed #if 0 in virt.c
- vGICv3 patch set restructured and more clearly separated into portions, according to old Eric's review
- Removed duplication of low-level vGICv3 code. Common helper routines are used instead.
- Put informative commit messages
