This series intends to setup the VFIO helper to allow
binding notifiers on different IRQs. Only MSIX IRQ type
considered so far.

Stefan suggested me to publish earlier to discuss.
If not too bad feedbacks I'll add some documentation in
"qemu/vfio-helpers.h" before reposting.

(NVMe block driver series will follow).
