Subject: -  Whack unused code -  Make the MemoryController use address ranges
 (via Range) instead of an address and a mask

base/remote_gdb.cc:
    reflect name change
dev/alpha_access.h:
    better include
dev/alpha_console.cc:
    -  FunctionalMemory no longer takes care of mapping my address into
    the proper address space.  It must be done locally.
    -  the memory controller no longer uses a mask, but a size, and the
    size is determined by the device, not the .ini file
    -  fix up address calculations to reflect the removal of a mask
    -  PhysicalMemory::getSize() -> PhysicalMemory::size()
dev/alpha_console.hh:
    -  FunctionalMemory no longer takes care of mapping my address into
    the proper address space.  It must be done locally.
    -  the memory controller no longer uses a mask, but a size, and the
    size is determined by the device, not the .ini file
    -  fix up address calculations to reflect the removal of a mask
    -  get rid of MmapDevice and inherit from FunctionalMemory
