The public API (struct rte_metric_name) includes the NULL terminator
byte in RTE_METRICS_MAX_NAME_LENGTH but the library itself internally
excludes it. This makes it possible for an application to receive an
unterminated name string. Fix be enforcing the NULL termination of all
name strings to the length that the public API expects.

This patch adds a new information metrics library. This Metrics
library implements a mechanism by which producers can publish
numeric information for later querying by consumers. Metrics
themselves are statistics that are not generated by PMDs, and
hence are not reported via ethdev extended statistics.
Metric information is populated using a push model, where
producers update the values contained within the metric
library by calling an update function on the relevant metrics.
Consumers receive metric information by querying the central
metric data, which is held in shared memory.
