Setting the SipHash hash size and setting its key is done with two
independent functions... and yet, the internals depend on both.
Unfortunately, the function to change the size wasn't adapted for the
possibility that the key was set first, with a different hash size.
This changes the hash setting function to fix the internal values
(which is easy, fortunately) according to the hash size.
evpmac.txt value for digestsize:8 is also corrected.

This was originally part of SipHash_Init. However, there are cases
where there isn't any key material to initialize from when setting the
hash size, and we do allow doing so with a EVP_PKEY control. The
solution is to provide a separate hash_size setter and to use it in
the corresponding EVP_PKEY_METHOD.

Only applies to algorithms that support it. Both raw private and public
keys can be obtained for X25519, Ed25519, X448, Ed448. Raw private keys
only can be obtained for HMAC, Poly1305 and SipHash

The core SipHash supports either 8 or 16-byte output and a configurable
number of rounds.
The default behavior, as added to EVP, is to use 16-byte output and
2,4 rounds, which matches the behavior of most implementations.
There is an EVP_PKEY_CTRL that can control the output size.
