10999f8ba8 If mps_key_spare_commit_limit and mps_key_spare are both given, then the latter takes precedence. 
If MPS_KEY_SPARE_COMMIT_LIMIT has a value greater than the commit limit, clamp the spare commit limit to 1.0.
Add smoke test coverage of MPS_KEY_SPARE, mps_arena_spare, and mps_arena_spare_set.
Document the deprecation of MPS_KEY_SPARE_COMMIT_LIMIT.
