Bring across the JDWP implementation.
This compiles and links, but does nothing until we fill out the 100 or so
unimplemented methods in "debugger.cc". Note that I also need to add the
extra command-line handling for the JDWP agent stuff, and add calls from
the runtime to the various "something interesting is going on" hooks.
