avoid a sign-extension bug in crypto_hash_function
* fns.c (to_uchar): Define.
(crypto_hash_function): Use it to convert some newly-signed
variables to unsigned, to avoid sign-extension bugs. For example,
without this change, (md5 "truc") would evaluate to
45723a2aff78ff4fff7fff1114760e62 rather than the expected
45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
