That said, I did go overboard here and converted all the struct/union
combinations I could find, but I'm not necessarily proposing to apply
all of them. I'm proposing patches 0001 through 0004, which are
relatively simple or in areas that have already changed a few times
recently (so backpatching would not be trivial anyway), and/or they
are somewhat close to my heart because they originally motivated this
work a long time ago. But if someone finds among the other patches
one that they particularly like, we could add that one as well.
I went through all commits and code changes are neat and clear.
But when I tried to build on my Macbook M4, it got 18 errors against cryptohash.c:

With the attached fix, the build passed then, "make check" also passed.
