Nuke the idea of <machine/options.h>. It completely defeats the purpose of fine-grain option dependencies.

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.
