      Fix some polling issues:
      
       - Don't background-poll disabled TAPs ... this was just a bug
         waiting to happen.  (And then it happened!)
      
       - Don't fail command line polls of disabled taps; that's not any
         kind of error, it's just that you can't do much.  But do show
         that tap-disabled status.
      
       - Spell "continuous" correctly in the variable name.  ;)
      
      Not resolved by this patch:  the need for an interlock whereby
      other code (like the JTAG layer) can block all other access to
      the JTAG layer, e.g. while enabling or disabling TAPs.  And
      that interlock needs to be timer-safe...

      Doc update:  say "jtag newtap ... -disable" records the
      state after exiting the RESET state, matching the only
      implementation we're working with so far (TI ICEpick-C).
      
      Matching code updates.  Now we can be sure that the
      "enabled" flag value is correct after JTAG resets.

      Fix a memory leak in jtag_tap_free():  unregister the event
      callback too.
      
      Also fix the associated conceptual bug in unregistering JTAG
      event callbacks:  since the same callback procedure is used
      many times with different callback data (a TAP handle), that
      data must be considered when unregistering any callback.
      
      This could fix some crashes after TAP registration errors,
      by making sure the reset event handler doesn't scribble over
      memory that's now used by something else.

      Minor jtag cleanup:
      
       - remove hidden assumption about JTAG event numbering
       - move function declarations to a header
       - some end'o'line whitespace
       - use "calloc" not "malloc + memset"
