Subject: implement vtophys and 32bit gdb support

src/arch/alpha/vtophys.cc:
src/arch/alpha/vtophys.hh:
src/arch/sparc/arguments.hh:
    move Copy* to vport since it's generic for all the ISAs
src/arch/sparc/isa_traits.hh:
    the Solaris kernel sets up a virtual-> real mapping for all memory starting at SegKPMBase
src/arch/sparc/pagetable.hh:
    add a class for getting bits out of the TteTag
src/arch/sparc/remote_gdb.cc:
    add 32bit support kinda.... If its 32 bit
src/arch/sparc/remote_gdb.hh:
    Add 32bit register offsets too.
src/arch/sparc/tlb.cc:
    cleanup generation of tsb pointers
src/arch/sparc/tlb.hh:
    add function to return tsb pointers for an address
    make lookup public so vtophys can use it
src/arch/sparc/vtophys.cc:
src/arch/sparc/vtophys.hh:
    write vtophys for sparc
src/base/bitfield.hh:
    return a mask of bits first->last
src/mem/vport.cc:
src/mem/vport.hh:
    move Copy* here since it's ISA generic
