Added "addr" "x" and "tlist" commands to kdbg.

Browse source 
addr  -- Displays address info from kdb_stabs.
x     -- Dumps memory.
tlist -- List threads.  Helps with bt, because normally, you don't know
         what the thread ids are or the stack addresses.
kdb_stabs.c: Fixed bug: length of module vs length of name.
kdb_serial.c: Added /KDSERIAL option allowing the user to type commands
              to the serial port.
