Cheng Chang b42fa1497f Support move semantics for PinnableSlice (#6374) ... Summary: It's logically correct for PinnableSlice to support move semantics to transfer ownership of the pinned memory region. This PR adds both move constructor and move assignment to PinnableSlice. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6374 Test Plan: A set of unit tests for the move semantics are added in slice_test. So `make slice_test && ./slice_test`.
