In non-DEBUG builds, `OffTheBooksCondVar::Wait` has `AUTO_PROFILER_THREAD_SLEEP`, but it's not in DEBUG builds.
`profiler_thread_sleep` does a `MOZ_ASSERT(mSleep == AWAKE)` in DEBUG builds, so the double call that happens in non-DEBUG wouldn't trigger the assertion!
This patch adds `AUTO_PROFILER_THREAD_SLEEP` in DEBUG `OffTheBooksCondVar::Wait`, to catch more misuses during development.

CondVar already calls `AUTO_PROFILER_THREAD_SLEEP`, which shouldn't be called recursively.
mozilla::Monitor also uses CondVar, so it shouldn't be surrounded by `AUTO_PROFILER_THREAD_SLEEP` either.

In the tests we now explicitly use "Main Process" (or similar) for the process
name in various places to avoid having to filter out a PID.
Also in `test_aboutmemory[34].xhtml`, the main process entries now appear
first, as they should, because the sorting code now looks for a "Main Process"
prefix, rather than an exact match.

In practice this shouldn't substantially change the behavior, but
it gets around being UB, and it shouldn't really cost us in terms
of performance. The alternative would be adding it to the TSAN
whitelist, which feels worse.

After the recent simplifications to the zoom code, they only take care
of forwarding the enlarge / decrease zoom messages.
We can do that via PBrowser instead, and get rid of the actors. We can
also remove ZoomChangeUsingMouseWheel. Zooming with the mouse wheel will
end up in a *ZoomChange event anyways, and the only consumer already
listened for them.

Implement org.gnome.Shell.SearchProvider2 D-Bus interface and enable it when
widget.gnome-search-provider.enabled pref is set, so this feature is disabled
by default.

This is in preparation for running the tail dispatcher off
nsIThreadObserver callbacks, which only work during regular
event processing.
Differential Revision: https://phabricator.services.mozilla.com/D72264
This is how it used to be, before the Quantum DOM stuff. We use
nsIThreadInternal because that supports thread observers, which we
leverage in the next patch.

The `mozilla::IsPod<HashMapEntry` specialisation was only needed for the static
assertions in "js/src/frontend/NameCollections.h". Part 3 removed those, so we
can now also remove `mozilla::IsPod<HashMapEntry`.
Drive-by change:
- Remove no longer needed "mozilla/PodOperations.h" include in mfbt/HashTable.h.
- And then fix up previously transitively included files for RootingAPI.h,
jsfriendapi.h, and Bench.cpp.

The problem in https://bugzilla.mozilla.org/show_bug.cgi?id=325392 was
misdiagnosed and then a generic fix in
https://bugzilla.mozilla.org/show_bug.cgi?id=485834 (the kungFuDeathGrip
in nsObserverService::RemoveObserver) was based on the wrong diagnosis.
The root problem in bug 325392 was not that we were calling
nsObserverService::RemoveObserver from the destructor, and then
reentering the destructor. The refcounting code stabilizes the refcount
to 1 before calling the destructor to avoid reentering a destructor. The
real problem was that we were deleting an XPCOM object manually after
creation but without ever holding a strong reference to it, and so not
going through the refcount stabilization (and then the destructor can
reenter of course).
The generic fix in bug 485834 was based on the spotfix in bug 325392,
that was then backed out when the proper fix for that bug landed. I
don't think we should keep this kungfuDeathGrip, I ran into it because
it causes issues with refcount logging (refcount logging always had an
issue with refcounting from a destructor).

This allows us to explicitly specify BrowsingContextGroups when synchronizing
them. A major advantage of this is that it means we can handle an attempt to
create a BrowsingContext with a parent which the content process is unaware of,
which is possible due to changes to the EnsureSubscribed logic in earlier
patches in this stack.
This is OK, because in the case where the content process cannot see its parent,
the parent must be imminently discarding.

The AppendElements overload accepting a mozilla::Array<Item, Length> is
redundant, since that is convertible to a mozilla::Span<const Item>, for which
a separate overload exists.
