24c776355f kernel.h: drop hex.h and update all hex.h users 
Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of
hex.h interfaces to directly #include <linux/hex.h> as part of the process
of putting kernel.h on a diet.

Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.

This change has been build-tested with allmodconfig on most ARCHes.  Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

fc0cf10c04 crypto/krb5: Implement crypto self-testing 
Implement self-testing infrastructure to test the pseudo-random function,
key derivation, encryption and checksumming.

Add the testing data from rfc8009 to test AES + HMAC-SHA2.

Add the testing data from rfc6803 to test Camellia.  Note some encryption
test vectors here are incomplete, lacking the key usage number needed to
derive Ke and Ki, and there are errata for this:
