Change gdbsupport not to rely on BFD

Browse Source 
This changes gdbsupport so that it no longer relies on BFD.  This is a
precursor to making gdbserver use the already-built gdbsupport,
because building gdbserver should not require BFD to be built.

The most notable change here is that CORE_ADDR is always a 64-bit
type.  This makes it so that gdb acts as if it were always built in
64-bit mode.
