Limit SharedSecret to 32 byte buffer 
The `SharedSecret` uses sha256 to hash the secret, this implies the
secret is 32 bytes of data.

Currently we use a buffer of 256 bytes, this is unnecessary.

Change the implementation of `SharedSecret` to use a 32 byte buffer.

Andrew Poelstra 9cab4e023d Revert "Overhaul interface to use zero-on-free SecretKeys" 
This reverts commit 9889090784.

This is not ready for primetime -- the move prevention also prevents
reborrowing, which makes secret keys nearly unusable.

Andrew Poelstra 9889090784 Overhaul interface to use zero-on-free SecretKeys 
Using the `secretdata` library, we can store SecretKeys in such a way
that they cannot be moved or copied, and their memory is zeroed out on
drop. This gives us some assurance that in the case of memory unsafety,
there is not secret key data lying around anywhere that we don't expect.

Unfortunately, it means that we cannot construct secret keys and then
return them, which forces the interface to change a fair bit. I removed
the `generate_keypair` function from Secp256k1, then `generate_nonce`
for symmetry, then dropped the `Secp256k1` struct entirely because it
turned out that none of the remaining functions used the `self` param.

So here we are. I bumped the version number. Sorry about this.
