Jeff King 28dc98e343 sha1dc: add collision-detecting sha1 implementation
This is pulled straight from:

  https://github.com/cr-marcstevens/sha1collisiondetection

with no modifications yet (though I've pulled in only the
subset of files necessary for Git to use).

This is commit 007905a93c973f55b2daed6585f9f6c23545bf66.

Further updates can be done like:

  git checkout -b vendor-sha1dc $this_commit
  cp /path/to/sha1dc/{LICENSE.txt,lib/*} sha1dc/
  git add -A sha1dc
  git commit -m "update sha1dc"

  git checkout -b update-sha1dc origin
  git merge vendor-sha1dc

Thanks to both Marc and Dan for making the code fit our
needs by doing both optimization work, cutting down on the
object size, and doing some syntactic changes to work better
with git. And to Linus for kicking off the "diet" work that
removed some of the unused code.

The license of the sha1dc code is the MIT license, which is
obviously compatible with the GPLv2 of git.
