Giving '0' (literal zero) to nsCOMPtr is now ambiguous, as both
nsCOMPtr(decltype(nullptr)) and nsCOMPtr(T*) could be used.
In any case, our coding standards mandate the use of 'nullptr' for pointers.
So I'm changing all zeroes into nullptr's where necessary.

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.

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.

By using nsCOMArray::Forget, we can pass the references we hold in an
nsCOMArray directly to the XPCOM caller, without having to go through an
extra cycle of AddRef/Release calls. This way should be slightly faster
and it also results in smaller code. Notice that we don't have to worry
about removing the OOM check in the places that use Forget(), because we
were already using moz_xmalloc to allocate the outparam array, and
moz_xmalloc aborts the process on OOM, just as Forget() does.
The nsNavHistoryFolderResultNode::GetQueries change is thrown in for fun.
In all of the places touched by this patch, the smart pointer we're
appending is about to become unused, so simply .forget()'ing its
reference into the appropriate nsCOMArray works just fine.
This aims at speeding up DELETE FROM moz_places like queries.
The primary reason of slowness is the FOR EACH ROW trigger that takes care of updating the moz_hosts table when places are removed.
Unfortunately Sqlite doesn't support FOR EACH STATEMENT triggers, that means the trigger will hit multiple times for pages in the same host.
The patch introduces an additional temp table to accumulate hosts during a delete, then a trigger takes care of updating moz_hosts only once per touched host, rather than once per removed place.

The problem is due to sanitization happening too late in the shutdown cycle.
The Sanitizer depends on Places shutdown, that recently moved to async shutdown.
That change caused shutdown to happen completely at profile-before-change, unfortunately
during that phase it's impossible to predict which services are already shutdown.
The patch restores the previous Places shutdown procedure, thus clients are notified
earlier, during profile-change-teardown.
Additional meaningful changes:
* Fixes FX_SANITIZE_TOTAL telemetry to properly count total time taken by sanitize.
* Makes each cleanup operation isolated from other errors to try cleaning up as most as possible.
* In case of multiple sanitization sub steps, each step is isolated by a try/catch, the last seen exception is reported upstream.
* Makes FX_SANITIZE_HISTORY actually measure history, not other random stuff.
* Removes TOPIC_SIMULATE_PLACES_MUST_CLOSE_1 since we can now just use profile-change-teardown for shutdown phase 1.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
