Subject: [PATCH 0/6] test_hash.c: refactor into KUnit

We refactored the lib/test_hash.c file into KUnit as part of the student
group LKCAMP [1] introductory hackathon for kernel development.

This test was pointed to our group by Daniel Latypov [2], so its full
conversion into a pure KUnit test was our goal in this patch series, but
we ran into many problems relating to it not being split as unit tests,
which complicated matters a bit, as the reasoning behind the original
tests is quite cryptic for those unfamiliar with hash implementations.

Some interesting developments we'd like to highlight are:

- In patch 1/6 we noticed that there was an unused define directive that
  could be removed.
- In patch 5/6 we noticed how stringhash and hash tests are all under
  the lib/test_hash.c file, which might cause some confusion, and we
  also broke those kernel config entries up.

Overall KUnit developments have been made in the other patches in this
series:

In patches 2/6 through 4/6 and 6/6 we refactored the lib/test_hash.c
file so as to make it more compatible with the KUnit style, whilst
preserving the original idea of the maintainer who designed it (i.e.
George Spelvin), which might be undesirable for unit tests, but we
assume it is enough for a first patch.

This is our first patch series so we hope our contributions are
interesting and also hope to get some useful criticism from the
community :)
