[v2,00/14] SHA-256 CVS and SVN patches

Message

brian m. carlson June 22, 2020, 6:04 p.m. UTC

I recently sent out part 2/3 of the SHA-256 work and then I realized
that I hadn't built with the CVS and SVN adapters.  So this is part
2.5/3 (or, to be pedantic, 3/4).

The patches are ordered roughly with test-only fixes, then SVN, and then
CVS.  There are no additional tests here because everything fails with
SHA-256 before and passes afterwards.

Changes from v1:
* Adopt Andreas's suggestion to preserve more of the structure of the
  original function.

Range-diff below.
