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.)

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.)
