[GSoC][PATCH 00/10] t: port reftable/block_test.c to the unit testing framework

[Chandra Pratap <chandrapratap3519@gmail.com>]

The reftable library comes with self tests, which are exercised
as part of the usual end-to-end tests and are designed to
observe the end-user visible effects of Git commands. What it
exercises, however, is a better match for the unit-testing
framework, merged at 8bf6fbd0 (Merge branch 'js/doc-unit-tests',
2023-12-09), which is designed to observe how low level
implementation details, at the level of sequences of individual
function calls, behave.

Hence, port reftable/block_test.c to the unit testing framework and
improve upon the ported test. The first patch in the series moves
the test to the unit testing framework, and the rest of the patches
improve upon the ported test.
