Add a documentation file Documentation/crypto/libcrypto.rst which provides a high-level overview of lib/crypto/. Also add several sub-pages which include the kernel-doc for the algorithms that have it. This makes the existing, quite extensive kernel-doc start being included in the HTML and PDF documentation. Note that the intent is very much *not* that everyone has to read these Documentation/ files. The library is intended to be straightforward and use familiar conventions; generally it should be possible to dive right into the kernel-doc. You shouldn't need to read a lot of documentation to just call `sha256()`, for example, or to run the unit tests if you're already familiar with KUnit. (This differs from the traditional crypto API which has a larger barrier to entry.) Nevertheless, this seems worth adding. Hopefully it is useful and makes LWN no longer consider the library to be "meticulously undocumented".
