PROTON-772: Remove all direct printing to stdout and stderr (missed one)
Added a check to ensure we don't log any transport trace messages unless at
least
one of the trace modes is enabled.
> Remove all direct printing to stdout and stderr.

> Key: PROTON-772
> URL: https://issues.apache.org/jira/browse/PROTON-772
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.8
> Reporter: Alan Conway
> Assignee: Alan Conway
> Fix For: 0.3
>
>
> A library should never, ever print anything directly to stdout/stderr unless
> explicitly requested to do so, as it may be linked with programs that need to
> control what they output to stdout/err or programs that have no stdout/err at
> all.
> Failures should be raised via the API error mechanism with appropriate
> message strings that the caller can display as they see fit. Informational
> log messages should be logged in a way that the caller can send them where
> they want or turn them off if they want.
