Preparation for updating bearssl, pull in updates to libsecureboot. o fix handling of some out-of-memory cases o allow more control over reporting of Verified/Unverified files. this helps boot time when console output is slow o recheck verbose/debug level after reading any unverified file o more debug support for vectx o hash_string to support fake stat for tftp o tests/tvo add -v to simply verify signatures o vets.c allow for HAVE_BR_X509_TIME_CHECK which will greatly simplify verification in loader o report date when certificate fails validity period checks Reviewed by: stevek Sponsored by: Juniper Networks, Inc.
