Deprecate MI version 1

MI version 1 is long since obsolete.  Rather than remove it
immediately (though I did send a patch for that), instead let's
deprecate it in GDB 13 and then remove it for GDB 14.

This version of the patch incorporates Simon's warning change, and
Luis' recommendation to mention the gdb versions here.
