Comment:

 Attached patch fixes every instance I could find; I did a grep on print,
 write and cout that did not start with '[', and skipped the directly-run-
 by-users tools (bindctl, loadzone, host, etc).

 Some prints I modified, a few I removed, since they didn't seem useful to
 me in any form.

 Next step is to replace this with real logging ;)
