walk-term for ISeqs should not be lazy, refs #121

Attach metadata only to terms that support it, refs #120

lvars-store should be a map and not a set, refs #122

Tests for LOGIC-120, LOGIC-121 and LOGIC-122
Merge branch 'master' of github.com:clojure/core.logic
LOGIC-116: In `migrate` the root may not have an entry in `km`, we
need to return the empty set in that case, otherwise will we'll call
into on nil which defaults to a seq causing the set only operations
like `disj` to fail.
LOGIC-71: fixed unifier reify vars issue some time ago. Documenting
the fix with a test.
LOGIC-36: another old unifier issue since resolved in 0.8.0. Adding a
test to document.
LOGIC-83: fix typo in test
LOGIC-108: recursive featurec. Add protocol IFeature. Implementers
should return something which can optional unify in the manner of
partial-map. Extend IPersistentHashMap to IFeature. Add test cases
demonstrating recursive behavior.
