// Cross-thread messaging for asset metrics.
/**
* @brief Base class for cross-thread requests made of the fetcher
*
* I believe the intent of the LLQueuedThread class was to
* have these operations derived from LLQueuedThread::QueuedRequest
* but the texture fetcher has elected to manage the queue
* in its own manner. So these are free-standing objects which are
* managed in simple FIFO order on the mCommands queue of the
* LLTextureFetch object.
*
* What each represents is a simple command sent from an
* outside thread into the TextureFetch thread to be processed
* in order and in a timely fashion (though not an absolute
* higher priority than other operations of the thread).
* Each operation derives a new class from the base customizing
* members, constructors and the doWork() method to effect
* the command.
*
* The flow is one-directional. There are two global instances
* of the LLViewerAssetStats collector, one for the main program's
* thread pointed to by gViewerAssetStatsMain and one for the
* TextureFetch thread pointed to by gViewerAssetStatsThread1.
* Common operations has each thread recording metrics events
* into the respective collector unconcerned with locking and
* the state of any other thread. But when the agent moves into
* a different region or the metrics timer expires and a report
* needs to be sent back to the grid, messaging across threads
* is required to distribute data and perform global actions.
* In pseudo-UML, it looks like:
*
* Main Thread1
* . .

*
*
* Key:
*
* SRE - Set Region Enqueued. Enqueue a 'Set Region' command in
* the other thread providing the new UUID of the region.
* TFReqSetRegion carries the data.
* SR - Set Region. New region UUID is sent to the thread-local
* collector.
* SME - Send Metrics Enqueued. Enqueue a 'Send Metrics' command
* including an ownership transfer of a cloned LLViewerAssetStats.
* TFReqSendMetrics carries the data.
* SM - Send Metrics. Global metrics reporting operation. Takes
* the cloned stats from the command, merges it with the
* thread's local stats, converts to LLSD and sends it on
* to the grid.
* AM - Agent Moved. Agent has completed some sort of move to a
* new region.
* TE - Timer Expired. Metrics timer has expired (on the order
* of 10 minutes).
* CP - CURL Post
* MSC - Modify Stats Collector. State change in the thread-local
* collector. Typically a region change which affects the
* global pointers used to find the 'current stats'.
* RSC - Read Stats Collector. Extract collector data cloning it
* (i.e. deep copy) when necessary.
