To meet FIPS 140 requirements, add support for building a kernel module
"fips140.ko" that contains various cryptographic algorithms built from
existing kernel source files. At load time, the module checks its own
integrity and self-tests its algorithms, then registers the algorithms
with the crypto API to supersede the original algorithms provided by the
kernel itself.
[ebiggers: this commit originated from "ANDROID: crypto: fips140 -
perform load time integrity check", but I've folded many later commits
into it to make forward porting easier. See below]

The directory tools/crypto and the only file under it never gets
built anywhere. This program should instead be incorporated into
one of the existing user-space projects, crconf or libkcapi.

Since now all crypto stats are on their own structures, it is now
useless to have the algorithm name in the err_cnt member.

This patch converts the getstat example tool to the recent changes done in crypto_user_stat
- changed all stats to u64
- separated struct stats for each crypto alg
