Move generic skbuff stuff from XFRM code to generic code so that
AF_RXRPC can use it too.
The kdoc comments I've attached to the functions needs to be checked
by whoever wrote them as I had to make some guesses about the workings
of these functions.

First of all, if the xfrm_state only gets used for input
packets this entropy is a complete waste.
Secondly, it is often the case that a configuration loads
many rules (perhaps even dynamically) and they don't all
necessarily ever get used.
This get_random_bytes() call was showing up in the profiles
for xfrm_state inserts which is how I noticed this.

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.

This patch converts IPSec/ESP to use the new block cipher type where
applicable. Similar to the HMAC conversion, existing algorithm names
have been kept for compatibility.

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!
