A few cleanups that I'll also apply to vfio-pci. First make intx
route checking non-fatal. vfio-pci has a fallback INTx mechanism
that doesn't rely on this, so we can already run on q35, but not if
we can't even probe for intx routing w/o blowing up. Next, both
vfio-pci and pci-assign test whether INTx routing has changed using
similar functions. Make this common. Finally, expose a way to
get the MSI message for an MSI vector. Again, both pci-assign and
vfio-pci need to do this to program the vector for KVM injection.
Thanks,
Alex
