Use factory to create histograms, and refcounts to track lifetimes
This is CL patch 377028 by Raman Tenneti, with minor changes to
make the try-bots happier.
It is cleanup that better ensures lifetimes of histograms (making it harder
for users to abuse them).
bug=16495 (repairs leak induced by the first landing)
bug=18840 (should make leaks less possible)
