Add "print debug foo" function safe to use in signal handlers, example:
_rthread_debug(3, "foo = %s", foo);
where output is to stderr and will only be printed if the current
debug level is >= 3. Messages with a debug level of 0 are always
printed. The level can be set from the environment (not enabled yet)
or with gdb by modifying variable _rthread_debug_level.
