c6d5a76721 ANDROID: fips140: add kernel crypto module
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]
