Merge branch 'ps/reftable-block-search-fix'

The reftable code has its own custom binary search function whose
comparison callback has an unusual interface, which caused the
binary search to degenerate into a linear search, which has been
corrected.

* ps/reftable-block-search-fix:
  reftable/block: fix binary search over restart counter
  reftable/record: fix memory leak when decoding object records
