Review comment:
Oh, I missed that -- so I can basically safely log a format string and
skip constructing the message entirely? i.e.
```guacd_log(GUAC_LOG_INFO, "Connection \"%s\" does not exist",
identifier);```
As for the level, this isn't a runtime error so much as a client error
though, akin to HTTP 400 "bad request" or 404 "not found", which to me sounds
more like an informative message if any; If you still think it's appropriate to
log this an error, however, please ping me and I'll adjust the PR.
