[Bro-Dev] Consistent error handling for scripting mistakes

I like what you & Robin sketch.  FWIW, it's hard for me to get excited
over the issue of leaks-in-the-face-of-error-recovery.  Presumably it would
take in practice a lot of error recovery before this actually hoses the
execution due to running out of memory.  At that point, it's not unreasonable
for things to keel over anyway.

An alternative/additional approach would be to introduce a notion of
"failure" as a first-class object.  In another life I used a language that
did that, and it worked remarkably well.  But clearly that's a bigger
undertaking than the valuable near-term notion of regularizing how Zeek
deals with errors.
