[tor/master] Use SHA256 in the replaycache, rather than SHA1

commit 2e9779e5d84db3e0d7b51ea34e73828253a298c2 Author: teor (Tim Wilson-Brown) <teor2345(a)gmail.com> Date: Tue Nov 24 09:08:53 2015 +1100 Use SHA256 in the replaycache, rather than SHA1 This migrates away from SHA1, and provides further hash flooding protection on top of the randomised siphash implementation.
