de17b66e31 Fix buffer length in scrypt 
The temporary XY buffer passed to the scrypt_smix C function should be
256r+64 bytes in length, but the Haskell code was only allocating 256r
bytes, causing the additional 64 to be written past the end of the
buffer.

See #91.

d7e26e34ee [random] add a seed capability with export/import from integer. 
It decomposes the drgNew call that was gathering entropy then
initializing a ChaChaDRG, into 2 new calls seedNew and drgNewSeed.

drgNew remains unchanged.

The integer importing capability, should be used when wanting to bring
reproducibility to a debugging problem or for testing, otherwise it's
probably a bad idea to use.

4c6b774a3d Do DSS truncation on verify 
RFC 4880 and FIPS 186-4 require that DSA signatures truncate the
hash to the size of q.  This changes Crypto.PubKey.DSA.verify
to do so in all cases.

5a2809a0f8 [ChaChaPoly1305] fix type error of example code 
The example code had a type mismatch.

    Couldn't match expected type ‘State’
                with actual type ‘CryptoFailable State’
    In the second argument of ‘appendAAD’, namely ‘st1’
    In the second argument of ‘($)’, namely ‘appendAAD hdr st1’

This is due to the following part:

    let st1 = ChaChaPoly1305.initialize key nonce
        st2 = ChaChaPoly1305.finalizeAAD $ ChaChaPoly1305.appendAAD hdr st1

`initialize` returns `CryptoFailable State`, not `State`.

This commit fixes the type mismatch, changes the return type of the
example function to `CryptoFailable ByteString`, and makes the code
to be immediately copy-and-paste-able.
