TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
support variable-length bit vectors. No functional change.
+TF/02 Improve the consistency of logging incoming and outgoing interfaces.
+ The I= interface field on outgoing lines is now after the H= remote
+ host field, same as incoming lines. There is a separate
+ outgoing_interface log selector which allows you to disable the
+ outgoing I= field.
