PROTON-2562: Fix pn_value_dump to output to a fixed size string buffer
Introduce a new fixed size string type that does not grow and works in a
fixed buffer.
This is then used by the logger to avoid dynamically
growing the logger output.
> Refactor logging so that it doesn't allocate any heap memory

> URL: https://issues.apache.org/jira/browse/PROTON-2562
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
>
> Currently the logging subsystem depends on the pn_string_t class to manage
> the messages that it sends out. This means that it is subject heap
> allocations at unknown time with unknown amounts.
> Given that a logging subsystem should always succeed and take as little time
> as possible, it would be much better to avoid any allocations at all, but at
> eliminating as many as possible will be a significant improvement.
