currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.
This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.

The launch script can output log messages, that should be text.
But it is not always true. E.g. "launch_UOS.sh -U 2" echo message
contain '\0', The 'grep' command will show "Binary file (xxxxxx)

If subsequent write is on the same address, maybe the compiler will optimize
the access of MMIO memory and only the last write takes effect.In such case
it is wrong. For example:
mmio_write_long(0x25, addr);
mmio_write_long(0x26, addr);
mmio_write_long(0x27, addr);
After volatile is added, it can avoid the above possible optimization and
assure that each write takes effect.
