This patch allows the caller to find out if the gdbstub actually did

What different actions do you envisage the caller will take? If they are reasonable, perhaps they should be explicitly specified in a return- code

Currently there are two failure cases:
  1) GDB had no transport available for its use (UART or otherwise)
2) "unexpected trap", usually another trap occurs while gdb is in control

I suppose we could have (1) -EIO and (2) -EBUSY.
My logic was that either gdb was available or not and that I needed to continue as if gdb was not enabled at all.
