In the recent codebase update (commit 8bf6fbd, 2023-12-09), a new unit
testing framework written entirely in C was introduced to the Git project
aimed at simplifying testing and reducing test run times.
Currently, tests for the reftable refs-backend are performed by a custom
testing framework defined by reftable/test_framework.{c, h}. Port
reftable/tree_test.c to the unit testing framework and improve upon
the ported test.

The first patch in the series is preparatory cleanup, the second patch
moves the test to the unit testing framework, and the rest of the patches
improve upon the ported test.
