Commit Message

Chandra Pratap June 6, 2024, 3:23 p.m. UTC 
reftable/pq_test.c exercises a priority queue defined by
reftable/pq.{c, h}. Migrate reftable/pq_test.c to the unit
testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework.
