Add test cases for the bits iter:
- Positive cases
- Bit mask representing a single word (8-byte unit)
- Bit mask representing data spanning more than one word
- The index of the set bit
- Nagative cases
- bpf_iter_bits_destroy() is required after calling
bpf_iter_bits_new()
- bpf_iter_bits_destroy() can only destroy an initialized iter
- bpf_iter_bits_next() must use an initialized iter
- Bit mask representing zero words
- Bit mask representing fewer words than expected
- Case for ENOMEM
- Case for NULL pointer

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.
