Merge branch 'ab/sha1dc'
The "collission-detecting" implementation of SHA-1 hash we borrowed
from is replaced by directly binding the upstream project as our
submodule. Glitches on minority platforms are still being worked out.
* ab/sha1dc:
sha1collisiondetection: automatically enable when submodule is populated
sha1dc: optionally use sha1collisiondetection as a submodule
