  1.  Kee the command-registration functions unchanged (discard
my xxx_wit_notif functions).
  2.  Don't emit option change of *all* gdb commands.  We have to
set 'reporting' commands via function 'set_cmd_notify', otherwise
commands are still 'no-reporting'.  I believe that frontends will
request more and more options changes, but changes of some gdb
options are useless to frontends.  It is noisy to send all option
changes.

Tom and Pedro's review comments are addressed in this version.
