Allow user space to seed / reset the RNG via a setsockopt.

This patch reuses alg_setkey to copy data into the kernel. The
alg_setkey is now used for two mechanisms: setkey and seeding.
The function is extended by the providing the function pointer
to the function handling the copied data.

As the alg_setkey is now usable for more than just setkey, it is renamed
to alg_setop.
Just call it setkey, there is no harm in treating the seed as a key
is there?

In fact we should have done this from the very start.
crypto_rng_reset should be renamed crypto_rng_setkey.

Cheers,
