Hello,
This small patch series transitions a couple more of our existing unit
test files to the Clar testing framework. This change is part of our
ongoing effort to standardize our testing framework to enhance
maintainability.
Changes in v2:
- fixes to the commit messages and how they read
- some code refactoring based on review
Thanks
Seyi

## Commit message ##
- t/unit-tests: remove lib-oid.{c,h,o}
+ t/unit-tests: implement clar specific oid helper functions
- The `lib-oid.c`, `lib-oid.h`, and `lib-oid.o files` are no longer needed
- since their equivalent functions have been implemented in unit-test.c
- and unit-test.h. This removes redundant code and ensures all unit
- test-related functionality is consolidated in a single location.
+ `get_oid_arbitrary_hex()` and `init_hash_algo()` are both required for
+ oid-related tests to run without errors. In the current implementation,
+ both functions are defined and declared in the
+ `t/unit-tests/lib-oid.{c,h}` which is utilized by oid-related tests in
+ the homegrown unit tests structure.
- Drop references to lib-oid from our `Makefile`, and `meson.build` files
- to prevent build errors due to missing files.
+ Adapt functions in lib-oid.{c,h} to use clar. Both these functions
+ become available for oid-related test files implemented using the clar
+ testing framework, which requires them. This will be used by subsequent
+ commits.

t/unit-tests: convert oidmap test to use clar test framework
Adapt oidmap test script to clar framework by using clar assertions
- where necessary. `cl_parse_any_oid` handles the necessary checks needed
- for the test to run smoothly.
+ where necessary. `cl_parse_any_oid()` ensures the hash algorithm is set
+ before parsing. This prevents issues from an uninitialized or invalid
+ hash algorithm.
Introduce 'test_oidmap__initialize` handles the to set up of the global
oidmap map with predefined key-value pairs, and `test_oidmap__cleanup`
frees the oidmap and its entries when all tests are completed.
- This streamlines the test suite, making individual tests self-contained
- and reducing redundant code.
+ The test loops through all entries to detect multiple errors. With this
+ change, it stops at the first error encountered, making it easier to
+ address it.
