2022-06-14	SL-17483: Make ThreadPool inherit LLInstanceTracker	Cosmic Linden
	(cherry picked from commit 41d6a0e222241606c317281e2f0b211e16813dd5)
2021-11-23	SL-16400: Add ThreadPool::start() method, and call it.	Nat Goodspeed
	It's sometimes important to finish other initialization before launching the threads in the ThreadPool, so make that an explicit step. In particular, we were launching the LLImageGL texture thread before initializing the GL context, resulting in all gray textures.

2021-11-05	SL-16202: Use WorkQueue::postTo() for texture create/post handshake.	Nat Goodspeed
	That is, when LLViewerFetchedTexture::scheduleCreateTexture() wants to call createTexture() on the LLImageGLThread, but postCreateTexture() on the main thread, use the "mainloop" WorkQueue to set up the handshake. Give ThreadPool a public virtual run() method so a subclass can override with desired behavior. This necessitates a virtual destructor. Add accessors for embedded WorkQueue (for post calls), ThreadPool name and width (in threads). Allow LLSimpleton::createInstance() to forward arguments to the subject constructor. Make LLImageGLThread an LLSimpleton - that abstraction didn't yet exist at the time LLImageGLThread was coded. Also derive from ThreadPool rather than LLThread. Make it a single-thread "pool" with a very large queue capacity.
2021-11-04	SL-16202: Use large WorkQueue size limits for mainloop and General.	Nat Goodspeed
	Give ThreadPool and WorkQueue the ability to override default ThreadSafeSchedule capacity. Instantiate "mainloop" WorkQueue and "General" ThreadPool with very large capacity because we never want to have to block trying to push to either.

2021-10-22	SL-16220: Add LL::ThreadPool class and a "General" instance.	Nat Goodspeed
	ThreadPool bundles a WorkQueue with the specified number of worker threads to service it. Each ThreadPool has a name that can be used to locate its WorkQueue. Each worker thread calls WorkQueue::runUntilClose(). ThreadPool listens on the "LLApp" LLEventPump for shutdown notification. On receiving that, it closes its WorkQueue and then join()s each of its worker threads for orderly shutdown. Add a settings.xml entry "ThreadPoolSizes", the first LLSD-valued settings entry to expect a map: pool name->size. The expectation is that usually code instantiating a particular ThreadPool will have a default size in mind, but it should check "ThreadPoolSizes" for a user override. Make idle_startup()'s STATE_SEED_CAP_GRANTED state instantiate a "General" ThreadPool. This is function-static for lazy initialization. Eliminate LLMainLoopRepeater, which is completely unreferenced. Any potential future use cases are better addressed by posting to the main loop's WorkQueue. Eliminate llappviewer.cpp's private LLDeferredTaskList class, which implemented LLAppViewer::addOnIdleCallback(). Make addOnIdleCallback() post work to the main loop's WorkQueue instead.
