I think libsodium matches the case.  The project is active and we should
track the updates.

OTOH for libb2 (blake2s), we need just two files (.h and .c) and those
seems to be a reference implementation of the algorithm and unlikely
to update, at least, frequently.  So just copying the files may work.

Note that it's not to say that I don't want to do the formal process
(because I've already done the task in my local changes).  I just don't
want to increase unnecessary files in the repository if possible (and
if preferable).

Anyway thank you for suggestions!
