em.c: change MAXMB to DEFMB, remove MEMSIZE and MEMMASK
...
It was confusing that MAXMB is the default memory size, so renamed it
to DEFMB. MEMSIZE was not necessary (half of MAXMB) and MEMMASK was
used only in mapva to limit physcal addresses when segmentation was
not enabled. However, this appears to be a bug, because it would
cause memory addresses larger than physical memory to wrap and succeed
rather than generate a missing memory check.

This option can be removed when the compile problems in emdev.h
(device drivers don't return a value in some cases) are fixed.
