[CRYPTO] Add faster DES code from Dag Arne Osvik

I've made a new implementation of DES to replace the old one in the kernel.
It provides faster encryption on all tested processors apart from the original
Pentium, and key setup is many times faster.

[CRYPTO] Remove unused iv field from context structure

The iv field in des_ctx/des3_ede_ctx/serpent_ctx has never been used.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
