Add config option to support memory allocations in 9-segment.
Internal "low memory" allocations are currently placed in the UMB
region (0xc0000-0xf0000). However, there have been reports of some
real machines that do not support DMA to this area of memory. So, add
a compile time config option (off by default) to support placing all
internal low-memory allocations at the end of the 640K real-memory
area (0x90000-0xa0000).
