Having all these limits set to core.streamFileThreshold sounds
reasonable. WindowCacheConfig is in a quite different package
(storage.pack vs. revwalk), so I'd read that value directly from the
Config. The actual definition of the default limit is currently located
in PackFile.DEFAULT_BIG_FILE_THRESHOLD. We could move that default to
Config so it's near to "core.streamFileThreshold" and we could add a
setter for the default there?
