PCI device assignment to guests (userspace)
Userspace patches for the pci-passthrough functionality.
The major updates since the last post are:
- Loop to add passthrough devices in pc_init1
- Handle errors in read/write calls
- Allow invocation without irq number for in-kernel irqchip
Other than this, several small things were fixed according to review comments received last time.
