      Fix a bug preventing ICEpick "enable that TAP" code from working:
      the "runtest" command wrongly finished with a JTAG reset, discarding
      the work the TAP enable handler just finished!  Instead, JTAG should
      stay in RUN/IDLE state.

      Extend the internal JTAG event handlers to cover enable/disable,
      and use those events to make sure that targets get "examined" if
      they were disabled when the scan chain was first set up:
      
       - Remove "enum jtag_tap_event", merge with "enum jtag_event",
         so C code can now listen for TAP enable/disable events.
      
       - Report those events so they can trigger callbacks.
      
       - During startup, make target_examine() register a handler to
         catch ENABLE events for any then-disabled targets.
      
      This fixes bugs like "can't halt target after enabling its TAP".
      
      One class of unresolved bugs:  if the target has an ETM hooked
      up to an ETB, nothing activates the ETB.  But starting up the
      ETM without access to the ETB registers fails...
