For crypto code we care about possible concerns during review, so add
more strict warnings. Fix all uses int to uint32_t/size_t comparisons,
make consistent use of size_t vs. uint32_t in crypto code.
Update test/tpm_test/bn_test.c to compile for checking big number
functions correctness.
BUG=none

There is no point in having separate implementation of always_memset()
which is slow and takes few extra bytes. Make memset's body available
as memset_core() with volatile dest *, thus making it always called
same as with always_memset(). Both memset() and always_memset() becomes
just wrappers on top.
BUG=none
TEST=make BOARD=cr50 CRYPTO_TEST=1; board boots, FIPS tests passes,
tpm_test.py works.

To implement FIPS module we need to bring many crypto functions in the
module boundary. Unfortunately, cryptoc is a third-party library used
by dcrypto code in cr50. Cryptoc is also not well-maintained and shared
with other projects.
