This patch tidies up the is_pci_in_array() function, making it take a single 'libxl_device_pci' argument rather than separate domain, bus, device and function arguments. The already-available COMPARE_PCI() macro can then be used and it is also modified to return 'bool' rather than 'int'. The patch also modifies libxl_pci_assignable() to use is_pci_in_array() rat= her than a separate open-coded equivalent, and also modifies it to return a 'bool' rather than an 'int'. NOTE: The COMPARE_PCI() macro is also fixed to include the 'domain' in its comparison, which should always have been the case.
