* gdbtk.c: (gdb_trace_status) new function.
        (gdbtk_init) added command "gdb_is_tracing".
        (tracepoint_notify) added passcount information.

        * tracepoint.c (trace_status_command): Recognize a boolean return
        value from the stub to indicate whether trace experiment is
        running.  Export this value as a global state variable
        (trace_running_p) for use by the GUI. (from Michael Snyder)
        (trace_pass_command) added call to modify_tracepoint_hook.

        * tracepoint.h export trace_running_p
