nagendra modadugu d7222a4956 CR50: add a constant time buffer equals implementation ...

Various cryptographic operations leak timing
information if comparisons are not executed
in constant time.  This change adds DCRYPTO_equals(),
a constant runtime comparator.

Also replace crypto related callsites that used
memcmp() as a binary comparator.

BUG=none
BRANCH=none
TEST=tcg tests pass
