This helps prevent a node from being killed/crashing in the middle
of writing a log, restarting, and eventually clobbering that log
file that never underwent the rotation/archival process.
The old `archive-log` and `post-terminate` scripts as used by
ZeekControl previously implemented this behavior, but the new logic is
entirely in the ASCII writer. It uses ".shadow" log files stored
alongside the real log to help detect such scenarios and rotate them
correctly upon the next startup of the Zeek process.
The stdout/stderr of child processes is now redirected over a pipe back
to the supervisor process so that it can prefix the output with
the name of the emitting node.
