While reviewing the initial KUnit tests for lib/packing, Przemek pointed out that the test values have duplicate bytes in the input sequence. In addition, I noticed that the unit tests pack and unpack on a byte boundary, instead of crossing bytes. Thus, we lack good coverage of the corner cases of the API. Add additional unit tests to cover packing and unpacking byte buffers which do not have duplicate bytes in the unpacked value, and which pack and unpack to an unaligned offset. A careful reviewer may note the lack tests for QUIRK_MSB_ON_THE_RIGHT. This is because I found issues with that quirk during test implementation. This quirk will be fixed and the tests will be included in a future change.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
