Main change is a callback for checking validity period of certificates.
Merge commit 'f6acb9b9f81c96ae7c9592bee1bb89c4357cc3e5'
Add -DHAVE_BR_X509_TIME_CHECK to libsecureboot/Makefile.inc
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

We need a valid st_dev, st_ino and st_mtime
to correctly track which files have been verified
and to update our notion of time.
ve_utc_set(): ignore utc if it would jump our current time
by more than VE_UTC_MAX_JUMP (20 years).
Allow testing of install command via userboot.
Need to fix its stat implementation too.
bhyveload also needs stat fixed - due to change to userboot.h
Call ve_error_get() from vectx_close() when hash is wrong.
Track the names of files we have hashed into pcr
For the purposes of measured boot, it is important
to be able to reproduce the hash reflected in
loader.ve.pcr
so loader.ve.hashed provides a list of names in the order they
were added.

For EFI at least, we can seed the environment
with VE_VERBOSE etc.

set our guard value immediately.
also replace call to ve_trust_init in opgp_sig.c:initialize with
call to openpgp_trust_init.

Since we can now add OpenPGP trust anchors at runtime,
ensure the latent support is available.
Ensure we do not add duplicate keys to trust store.
Also allow reporting names of trust anchors added/revoked
We only do this for loader and only after initializing trust store.
Thus only changes to initial trust store will be logged.

UEFI related headers were copied from edk2.
A new build option "MK_LOADER_EFI_SECUREBOOT" was added to allow
loading of trusted anchors from UEFI.
Certificate revocation support is also introduced.
The forbidden certificates are loaded from dbx variable.
Verification fails in two cases:
There is a direct match between cert in dbx and the one in the chain.
The CA used to sign the chain is found in dbx.
One can also insert a hash of TBS section of a certificate into dbx.
In this case verifications fails only if a direct match with a
certificate in chain is found.
