beorn7 3b9c421a69 Weed out all the [Gg]et* method names. 
The only exception is getNumChunksToPersist to avoid naming the struct
member numChunksToPersist in a weird way.

Julius Volz 267fd34156 Switch Prometheus to use github.com/prometheus/log. 
This change is conceptually very simple, although the diff is large. It
switches logging from "github.com/golang/glog" to
"github.com/prometheus/log", while not actually changing any log
messages. V(1)-style logging has been changed to be log.Debug*().

beorn7 7c6466d476 Reserve only ~1M FPs for the mapping. 
That reduces the chance of having a fingerprint in the reserved area.
