2130ba98c8359b08d97fb16d84dfd05687005dcf by Abseil Team <absl-team@google.com>:

Tweaking the documentation of c_all_of to state the effect more directly.

4732289bf4b56123fed113e36be4710b55c6a6c7 by Greg Falcon <gfalcon@google.com>:

Improve the quality of absl::Hash<std::vector<bool>>.

This previously dispatched to std::hash<vector<bool>>, which suffers from trivial collisions on many platforms.  (They often hash the internal words but no size info, so that, e.g., {1, 1} and {1, 1, 0} collide.)

Also extended the unit test to exercise this.

1c5f3934230a7669f74c96b305251786a265e235 by Greg Falcon <gfalcon@google.com>:

Add broader testing of absl hash contracts in the hash unit test.

In particular, test that the hash erasure mechanism works.

Rename node_hash_policy to node_slot_policy.

Motivation: we can potentially reuse this code for node_btree_*.
