Avi Kivity d17b05e911 Merge 'Adding Optimized pseudo floating point estimated histogram' from Amnon 
"
This series Adds a pseudo-floating-point histogram implementation.
The histogram is used for time_estimated_histogram a histogram for latency tracking and then used in storage_proxy as a more efficient with a higher resolution histogram.

Follow up series would use the new histogram in other places in the system and will add an implementation that supports lower values.
Fixes #5815
Fixes #4746
