- Add a function db_alt_break which recognizes the character sequence used to

  implement ALT_BREAK_TO_DEBUGGER.  The caller provides a pointer to a state
  variable to allow different state to be maintained for separate instances of
  a device.
- Use struct vm_map * instead of vm_map_t in db_break.h to avoid its users
  needing to include vm headers.
