m_active to i915_active instead. As part of that process, we move i915_gem_active out of i915_request.c into i915_active.c to start separating the two concepts, and rename it to i915_active_request (both to tie it to the concept of tracking just one request, and to give it a longer, less appealing name).

We expect these to be infrequently used and quick to allocate, so there is little benefit in keeping the tree cached and we would prefer to return the pages back to the system in a timely fashion. This also means that when we finalize the struct as a whole, we know as the activity tracker must be idle, the tree has already been released. Indeed we can reduce i915_active_fini() just to the assertions that there is nothing to do.

However, we may want to track other resources aside from VMA, or we may want to split a VMA into multiple independent regions and track each separately. For this purpose, generalise our request tracking (akin to struct reservation_object) so that we can embed it into other objects. v2: Tweak error handling during selftest setup.
