This is v12 of the server side changes to enable vfio-user in QEMU.

Thanks so much for reviewing this series and sharing your feedback.

We made the following changes in this series:
[PATCH v12 13/14] vfio-user: handle device interrupts
 - Renamed msi_set_irq_state() and msix_set_irq_state() as
   msi_set_mask() and msix_set_mask() respectively
 - Added missing return statement for error case in msi_set_mask()

Thank you very much!
