Cleanup histogram classes mixing SetFlags into FactoryGet arguments
Generic cleanup of histogram class, renaming *FactoryGet to FactoryGet,
along with reformatting.
The macros were cleaned up to use common sub-macros rather than
repeating code as much.
Removed ThreadSafeHistogram (and associated ASSET_HISTOGRAM macros)
since this class was not getting used.
I introduced UMA_HISTOGRAM_ENUMERATION to support the common use
of LinearHistograms to count various enumerated values.
I added a Flags argument to all the FactoryGet routines to help avoid
needing to call SetFlags each time a new sample is Add()ed. This also
simplifies the code.
This will all help prepare for a "don't histogram at all" macro setting
so that I can test the impact of the histogram macro calls on
performance (since there are now so many active histograms).
