Cleanup glog and add real caller information.
In general, we've learned that logging must be avoided at all
costs in the hot path. It's unlikely that the optimizations
here were significant in any case, since buffer would certainly
escape.
This also adds a test to ensure that the caller identification
works as expected, and so that logging can be benchmarked.
