Peter Grehan a9f9f6ce08 Change ofw_readin/ofw_copyin to map the entire region before
copying, rather than a page at a time. This was creating far
too many single-page mappings, and eventually OFW overflowed
some internal data structure and refused to map any more.
The new algorithm creates far less mappings and fixed a bug
where multiple mappings for the same page would be created.

'Twas known this was a problem, but only became urgent when the
install CD's mfs_root grew large enough to cause the overflow.
