Comment-only change: annotate exit() calls.

Sometimes when we call exit(), it's because the process is
completely hopeless: openssl has a broken AES-CTR implementation, or
the clock is in the 1960s, or something like that.

But sometimes, we should return cleanly from tor_main() instead, so
that embedders can keep embedding us and start another Tor process.

I've gone through all the exit() and _exit() calls to annotate them
with "exit ok" or "XXXX bad exit" -- the next step will be to fix
the bad exit()s.

First step towards 23848.
