Switch to tracking activity via i915_active on individual nodes, only
keeping a list of retired objects in the cache, and reaping the cache
when the engine itself idles.

For convenience in avoiding inline spaghetti, keep the type definition
as a separate header.

Function i915_gem_batch_pool_init() failed to follow obj-verb
naming schema. Fix that by swapping function parameters.
While here, change license text to SPDX format.
v2: use intel_engine_init_batch_pool (Chris) as proxy (Michal)

We should not rely on obj->active being uptodate unless we manually
flush it. Instead, we can verify that the next available batch object is
idle by looking at its last active request (and checking it for
completion).
v2: remove the struct drm_device forward declaration added in the
process of removing its necessity

Now with the trimmed memcpy before the command parser, we try to
allocate many different sizes of batches, predominantly one or two
pages. We can therefore speed up searching for a good sized batch by
keeping the objects of buckets of roughly the same size.
v2: Add a comment about bucket sizes

In the next patch, I want to use the structure elsewhere and so require
it defined earlier. Rather than move the definition to an earlier location
where it feels very odd, place it in its own header file.
