[PATCH 0/3] update sha1dc from PR #36

This hopefully fixes the Solaris SPARC issue & doesn't cause regressions elsewhere, e.g. on Cygwin. Adam, it would be great if you could test that platform.

I've already confirmed with Michael Kebe + another SPARC user (CosmicDJ on Freenode #Solaris) that it works on Solaris SPARC. The question is whether it breaks anything else.

Per the upstream pull request: https://github.com/cr-marcstevens/sha1collisiondetection/pull/36

Marc would (understandably) like some wider testing of this before merging it into the upstream project.

WRT the submodule URL & branch changing: I have no idea how git-submodule handles this in the general case, but it Just Works with GitHub because it allows fetching arbitrary SHA1s that any ref (including pull req refs) point to. So on top of pu just doing "git submodule update" works to update to the new copy.

  sha1collisiondetection: automatically enable when submodule is

  sha1dc: update from my PR #36
  sha1dc: optionally use sha1collisiondetection as a submodule
