/*
 * Classes and utility functions for per-thread and per-region
 * asset and experiential metrics to be aggregated grid-wide.
 *
 * The basic metrics grouping is LLViewerAssetStats::PerRegionStats.
 * This provides various counters and simple statistics for asset
 * fetches binned into a few categories.  One of these is maintained
 * for each region encountered and the 'current' region is available
 * as a simple reference.  Each thread (presently two) interested
 * in participating in these stats gets an instance of the
 * LLViewerAssetStats class so that threads are completely
 * independent.
 *
 * The idea of a current region is used for simplicity and speed
 * of categorization.  Each metrics event could have taken a
 * region uuid argument resulting in a suitable lookup.  Arguments
 * against this design include:
 *
 *  -  Region uuid not trivially available to caller.
 *  -  Cost (cpu, disruption in real work flow) too high.
 *  -  Additional precision not really meaningful.
 *
 * By itself, the LLViewerAssetStats class is thread- and
 * viewer-agnostic and can be used anywhere without assumptions
 * of global pointers and other context.  For the viewer,
 * a set of free functions are provided in the namespace
 * LLViewerAssetStatsFF which *do* implement viewer-native
 * policies about per-thread globals and will do correct
 * defensive tests of same.
 *
