Merge branch 'gt/t-hash-unit-test'
A pair of test helpers that essentially are unit tests on hash algorithms have been rewritten using the unit-tests framework. * gt/t-hash-unit-test: t/: migrate helper/test-{sha1, sha256} to unit-tests/t-hash strbuf: introduce strbuf_addstrings() to repeatedly add a string
