Calling VFY_VerifyDigestDirect causes the provided SECKEYPublicKey to be
reimported to the softoken regardless of if it already exists on it. EC keys
must be verified upon import (to see if the point is on the curve to avoid some
small subgroup attacks), and so repeatedly doing this with a static key (say,
for example, a key corresponding to a built-in certificate transparency log) is
inefficient. This patch alters the certificate transparency implementation to
import these keys each once and then use PK11_Verify for ECDSA signature
verification, which doesn't have the same drawback.
Since this change causes CertVerifier to hold an NSS resource (via its
MultiLogCTVerifier having a list of CTLogVerifier, each of which now has a
SECKEYPublicKey), nsNSSComponent has to make sure it goes away before shutting
down NSS. This patch ensures this happens in nsNSSComponent::ShutdownNSS().

(adapted from bug 1349762 comment 0)
Google Trust Services (GTS) recently purchased two roots from GlobalSign that
are both enabled for EV treatment: "GlobalSign Root CA - R2" and "GlobalSign ECC
Root CA - R4".
However, GTS does not have an EV audit, so we are going to turn off EV treatment
for both of those root certificates.
But "GlobalSign Root CA - R2" has intermediate cert "GlobalSign Extended
Validation CA - SHA256 - G2" that continues to be controlled by GlobalSign, to
be used to migrate their customers off dependence on that root.
This patch removes EV treatment for "GlobalSign ECC Root CA - R4". It also
removes EV treatment for all chains rooted in "GlobalSign Root CA - R2" unless
the "GlobalSign Extended Validation CA - SHA256 - G2" intermediate is in the
chain.
