This patch removes the duplicate ipv6_{auth,esp,comp}_hdr structures since
they're identical to the IPv4 versions. Duplicating them would only create
problems for ourselves later when we need to add things like extended
sequence numbers.
I've also added transport header type conversion headers for these types
which are now used by the transforms.

The keys are only used during initialisation so we don't need to carry them
in esp_data. Since we don't have to allocate them again, there is no need
to place a limit on the authentication key length anymore.

This patch converts IPsec to use the new HMAC template. The names of
existing simple digest algorithms may still be used to refer to their
HMAC composites.
The same structure can be used by other MACs such as AES-XCBC-MAC.
This patch also switches from the digest interface to hash.

The header file linux/crypto.h is only needed by a few files so including
it in net/xfrm.h (which is included by half of the networking stack) is a
waste. This patch moves it out of net/xfrm.h and into the specific header
files that actually need it.

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!
