idlen -> digest_{,string_}len
In my early sha256 I've used `idlen' to parametrize the digest length, but it's ambigous since it could refer both to the digest length or to the digest _string_ length. I'd like to standardize in digest_len / digest_string_len, even if requires a few more chars than `idlen'. Diff below renames all the offender (the rest of the tree is using these names already.)
