update Octave Project Developers copyright for the new year
In files that have the "Octave Project Developers" copyright notice,
update for 2021.
In all .txi and .texi files except gpl.txi and gpl.texi in the
doc/liboctave and doc/interpreter directories, change the copyright
to "Octave Project Developers", the same as used for other source
files. Update copyright notices for 2022 (not done since 2019). For
gpl.txi and gpl.texi, change the copyright notice to be "Free Software
Foundation, Inc." and leave the date at 2007 only because this file
only contains the text of the GPL, not anything created by the Octave
Project Developers.
Add Paul Thomas to contributors.in.

The GNULIB, contains even more HMAC based algorithms, c.f. https://www.gnu.org/software/gnulib/MODULES.html#module=crypto/hmac-md5 so a future project might be including these algorithms as well, adding a third key input parameter. There is also a GNULIB "high-level" interface to Libcrypt. It might be easier to use, but it introduces a new build dependency, so better stick to the "low-level" functions for now. */ #if defined (HAVE_CONFIG_H) # include "config.h" #endif #include <string> #include "lo-hash.h" #include "defun.h" #include "error.h" #include "ov.h" #include "ovl.h" OCTAVE_NAMESPACE_BEGIN DEFUN (hash, args, , doc: /* -*- texinfo -*- @deftypefn {} {} hash (@var{hfun}, @var{str}) Calculate the hash value of the string @var{str} using the hash function @var{hfun}.
