t/unit-tests: finalize migration of reftable-related tests

2025-07-24T18:46:04Z

The old `lib-reftable.{c,h}` implemented helper functions for our homegrown unit-testing framework. As part of migrating reftable-related tests to the Clar framework, Clar-specific versions of these functions in `lib-reftable-clar.{c,h}` were introduced. Now that all test files using these helpers have been converted to Clar, we can safely remove the original `lib-reftable.{c,h}` and rename the Clar- specific versions back to `lib-reftable.{c,h}`. This restores a clean and consistent naming scheme for shared test utilities. Finally, update our build system to reflect the changes made and remove redundant code related to the reftable tests and our old homegrown unit-testing setup. `test-lib.{c,h}` remains unchanged in our build system as some files particularly `t/helper/test-example-tap.c` depends on it in order to run, and removing that would be beyond the scope of this patch.

t/unit-tests: convert reftable stack test to use clar

2025-07-24T18:46:04Z

Adapt reftable stack test file to use clar by using clar assertions where necessary. This marks the end of all unit tests migrated away from the `unit-tests/t-*.c` pattern, there are no longer any files matching that glob. Remove the sanity check for `t-*.c` files to prevent Meson configuration errors during CI and local builds. Signed-off-by: Seyi Kuforiji Signed-off-by: Junio C Hamano
