ext4: move halfmd4 into hash.c directly
The "half md4" transform should not be used by any new code. And fortunately, it's only used now by ext4. Since ext4 supports several hashing methods, at some point it might be desirable to move to something like SipHash. As an intermediate step, remove half md4 from cryptohash.h and lib, and make it just a local function in ext4's hash.c. There's precedent for doing this; the other function ext can use for its hashes -- TEA -- is also implemented in the same place. Also, by being a local function, this might allow gcc to perform some additional optimizations. Signed-off-by: Jason A.
