DISPATCH-2222: avoid per-message logging overhead when not tracing
This closes #1330
> Avoid cpu-intensive message string-ify of every received AMQP message
> ---------------------------------------------------------------------
>
> Key: DISPATCH-2222
> URL: https://issues.apache.org/jira/browse/DISPATCH-2222
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 1.17.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Major
> Fix For: 1.18.0
>
>
> A call to log_link_message() is made for every received AMQP message. This
> function logs a string-ified version of the message at level QD_LOG_TRACE.
>
> log_link_message() parses out each message and summarizes it into a string
> buffer before logging. This stringify operation is cpu-intensive. According
> to flamegraphs it occupies 5% of the compute budget.
>
> The string-ify operation should be avoided if the message log level doe not
> have TRACE enabled.
