MOZ_ASSERT() is basically equivalent to NS_ASSERTION().
PSM already uses MOZ_ASSERT() for new code, so there's no need to use
NS_ASSERTION() as well.

When doing TLS session resumption, the AuthCertificate hook is bypassed, which
means that the front-end doesn't know whether or not to show the EV indicator.
To deal with this, the platform attempts an EV verification. Before this patch,
this verification lacked much of the original context (e.g. stapled OCSP
responses, SCTs, the hostname, and in particular the first-party origin key).
Furthermore, it was unclear from a code architecture standpoint that a full
verification was even occurring. This patch brings the necessary context to the
verification and makes it much more clear that it is happening. It also takes
the opportunity to remove some unnecessary EV-related fields and information in
code and data structures that don't require it.

This makes a lot of code more compact, and also avoids some redundant nsresult
checks.
The patch also removes a handful of redundant checks on infallible setters.
This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.
mozilla::BitwiseCast does the same thing, but provides static asserts that
mitigate some of the risk of using reinterpret_cast.

nsPSMUITracker was problematic. Apparently it was originally intended to prevent
NSS shutdown while NSS-related UI operations were going on (such as choosing a
client certificate). However, when nsNSSComponent would receive the event that
told it to shutdown NSS, it would attempt to call
mShutdownObjectList->evaporateAllNSSResources(), which would call
mActivityState.restrictActivityToCurrentThread(), which failed if such a UI
operation was in progress. This actually prevented the important part of
evaporateAllNSSResources, which is the releasing of all NSS objects in use by
PSM objects. Importantly, nsNSSComponent didn't check for or handle this failure
and proceeded to call NSS_Shutdown(), leaving PSM in an inconsistent state where
it thought it was okay to keep using the NSS objects it had when in fact it
wasn't.
In any case, nsPSMUITracker isn't really necessary as long as we have the
nsNSSShutDownPreventionLock mechanism, which mostly works and is what we should
use instead (or not at all, if no such lock is needed for the operation being
performed (for example, if no NSS functions are being called)).

part was modifying MFBT's moz.build to reflect the new naming.
