Hello

This patch is a try to implement a generic crypto driver statistics.
The goal is to have an "ifconfig" for crypto device.

Some driver tried to implement this via a debugfs interface.
This serie do it directly in the crypto API and give access to stats
via the crypto_user(netlink) API.
Then an userspace tool will collect information via netlink.
Note that this userspace tool is heavily copied from libkcapi and if
Stephan Mueller agree, I will made a PR for adding getstat to it.

Example of output:
gcc getstat.c -o getstat && ./getstat

Futur possible additions:
- Add a "number of needed fallback" statistics.
- maximum request size

Regards

Changes since RFC:
- Use cryptouser(netlink) instead of /sys
- Use atomic_t instead of unsigned long
- moved stat code into dedicated inline function
- spelling fixes
