[PATCH 00/13] qemu-kvm: device assignment cleanups and upstream diff reductions

[Jan Kiszka <jan.kiszka@web.de>]

This series basically consists of two halves. The first one applies a
few smaller cleanups to qemu-kvm to improve similarity with upstream.
This includes the recently discussed removal of -enable-nesting.

The second half starts with two device assignment fixes and then applies
some refactorings, specifically dropping the libpci dependency and
enabling the revert of some qemu-kvm private PCI core changes. The
latter is achieved by simplifying the access control management to the
passed-through device's config space. That also saves 100 LOC.

Note that this series was tested with upstream commit af2be20777 ("Fix
fallouts from Linux header inclusion") applied and probably depends on
it also mechanically.

Please review/merge.
