PCI and IRQ rework, pci.c rewritten from ground up, fixes numerous issues such as the bridge being added when the number of normal PCI devices equals the number of normal PCI slots, Windows 95 PCI operation on Intel 430NX, sharing of PCI IRQ's with non-PCI level-triggered devices, having both configuration mechanisms operating at the same time (ALi M1435), etc., and makes the code much more readable.
