Regression: Entry error after failure or during validation is not propogating.

Regression: Entry error after failure or during validation is not propogating.

When an Entry fails and successfully executes a failsafe, the failure is not propagated.
The failsafe is meant to bail out and not continue onward, so after a successful or failed failsafe, return F_failure (with error bit as appropriate).

When passing --validate without --test, the program is not exiting as it should.
This is because the state is not being handled just like the status is not being handled.

When joining threads, be sure to reset the identifiers.

Remove now extra Exit processing block.
This is now handled fully by the cancellation function.

Restore the thread enabled state after operating failsafe.

Get rid of simulate variable, instead use the console parameter directly.
This saves memory by a trivial amount.
