This patchset extends statistics reporting to include peak and
average data-rate metrics. It comes in two parts: a statistics
reporting library, and a bitrate calculation library that uses
it. This structure is intended to seperate statistic reporting
from ethdev and allow more flexible metric registration.

Note that this series integrates a third part for latency metric.

v10 changes:
* Rebased
* Relocated some config-related directives.
* Removed incorrect capitalisations in API docs.
* Formatting & detail corrections in release notes.
* Moved around struct member descriptions.
* Rewritten rte_metrics.h file description.
* Rewritten description of RTE_METRICS_GLOBAL.
* Used 'producers' and 'consumers' as terms.
* Removed markup (bold text) in Doxygen tags.
* Added programming guide section.

Thanks for adding the prog guide section. It helps.

I think there are three remaining questions:
- When the metrics computation are done? (in which thread?)
- May the few lines of computation code be done differently when tightly
integrated in an application logic?
- Could it be hosted in a separate repository on dpdk.org?
