move and split pcs_bus_{mem,io}_common.c, so that: (1) object code can be shared (where the hardware makes that possible), and (2) so that the file names better describe the systems which use them. (the pci_swiz* files are for machines whose PCI interfaces require address "swizzling." Later, there will be probably be other sets, e.g. pci_bwx* for machines whose chipsets can easily deal with the Alpha BWX extensions when doing device accesses.)

implement APECS and LCA 'bus' functions, and share them between the two chipsets, since they're the same.

by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries. This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS options, which is present but commented out in the ALPHA config file. In ELF-format kernels, these strings are present in the kernel binary but are not loaded into memory. (In ECOFF-format kernels, there's no easy way to keep them from being loaded, so they _are_ loaded into memory.)

split the APECS and LCA bus memory and I/O functions. Most of them still do the same things, but the extent maps have to be managed differently, since the two chipsets provide different memory and I/O region mapping possibilities.
