- Change Fingerprints to be simple uint64s.
- Deal sensibly with missing metric names.
- Enable finer-grained time resolution.
Merge this concurrently with the merge of the new storage backend into
prometheus/prometheus.

Colliding labels can happen e.g. when an exporter job is scraped and already
includes "job" labels for its samples in /metrics. In this case, a
collisionPrefix of "exporter_" is added to the colliding target labels, but the
specifics (the collision prefix) are managed by Prometheus, not the client
library.
This commit introduces all relevant server-side artifacts such that the
Result streams can be used by external parties for one-off tools and
such. This will ultimately better enable us to support additional
wireformats with much more ease.
