netlist: Potential regression trigger.

* Removed update and NETLIB_UPDATE completely.
* Startup initialization order may change.
* This may cause regression tests to trigger. This is expected. Logic
TTL devices do not have a defined power-up state. That's why reset
circuits exist which create a reset signal *after* all power supply
lines are stable.
