Modified Files:
        syssrc/sys/arch/alpha/common: sgmap_common.c sgmap_typedep.c sgmapvar.h
        syssrc/sys/arch/alpha/include: bus.h

Log Message:
Simplify the SGMAP code a bit, and move SGVA allocation out of a
common routine into the individual load routines, since each load
routine needs to muddle with the "internals" of this operation.

Add a `prefetch threshold' member to the bus_dma_tag_t, so that
eventually we can determine whether or not to allocate a spill
page on a per-mapping basis.
