Let's do bug #1769910 actually right. 

My original implementation was computing averages and medians.  Now we do binning, as requested.  So much simpler, too!  In addition, it fixes a bug where when hoping across activities we were only accounting for the last activity as the total time; now we count the time from the start of the initial activity.

This also includes some reduction and optimization of the activity manager dumpsys output.
