These types were already non-nullable, with the serializer implementation not
supporting nullptr values. This patch converts the uses to be explicitly
non-nullable, and adds the relevant `WrapNotNull` changes.

This makes various changes to the named lookup/navigation code to make
them more precise, and avoid issues which could happen if a window is
closed while script is still executing.
This also should improve handling for inactive windows in some cases, by
more frequently working off of the WindowContext tree rather than the
BrowsingContext tree.
As part of these changes, some behaviour was changed around e.g. the
file URI exception to avoid the deprecated nsIPrincipal::GetURI method.
I don't believe the behaviour should have changed in a meaningful way.

BrowsingContext::ShouldAddEntryForRefresh expects to be passed the current URI,
to determine if it's the same as the URI for the new load (we shouldn't add a
new entry if they are the same). Before this patch, in the child process we call
BrowsingContext::ShouldAddEntryForRefresh from nsDocShell::MoveLoadingToActiveEntry
(nsDocShell::CreateContentViewer -> Embed -> MoveLoadingToActiveEntry), passing
nsDocShell's mCurrentURI. However, by that point nsDocShell::CreateContentViewer
has already set the mCurrentURI to the newly loading URI (through
nsDocShell::OnNewURI). In the parent process we do pass the correct URI to
BrowsingContext::ShouldAddEntryForRefresh, so the session history ends up being
correct, but depending on timing of the IPC messages there's a brief moment where
index and length are incorrect in the child process (child process and parent
process get a different answer from BrowsingContext::ShouldAddEntryForRefresh).
This causes intermittent failures in the test at
docshell/test/mochitest/test_bug1742865.html.

We'd return early anyhow later in nsDocShell::InternalLoad.
The patch is based on code inspection. If one is closing the window while printing, we could get to this state, among other cases.

Move it to the mozilla::widget namespace.
Use enum classes for transparency, popup type, popup level, etc.
Mostly automated with sed, but there were a few manual changes required
as well in windows code because they relied on Atomic<TransparencyMode>
working (which now doesn't because TransparencyMode is 1 byte instead of
4 bytes).

Implementations of nsIEmbeddingSiteWindow and nsIBaseWindow largely
overlap, and where they don't, the nsIEmbeddingSiteWindow implementation
of the otherwise shared interface is primarily stubbed out with the
exception of Get/SetDimensions().
This patch moves a reimplementation of Get/SetDimensions() from
nsIEmbeddingSiteWindow to nsIBaseWindow. The other methods of
nsIEmbeddingSiteWindow remain covered by nsIBaseWindow.
Get/SetDimensions() can be implemented as part of nsIWebBrowserChrome
where nsIBaseWindow is not necessary. This removes the need for
nsIEmbeddingSiteWindow.
Blur() has also been moved to nsIWebBrowserChrome, as only
nsContentTreeOwner has an actual implementation which we in theory also
want to call from BrowserChild/Parent, but the spec suggests to
"selectively or uniformly ignore calls".
GetVisibility() had an implementation in BrowserChild that pretended to
always be visible. Instead of providing an interface for that,
nsDocShell now handles the not implemented case for tree owners.
nsIEmbeddingSiteWindow::GetSiteWindow() used to call through to
nsIBaseWindow::GetParentNativeWindow().
The Get/SetDimensions() implementation has been replaced with a strongly
typed setter, which is now also used directly from nsGlobalWindowOuter
to avoid problems that come with autodetecting unchanged dimensions,
when the current dimensions are outdated (e.g. immediately reverting a
change can be ignored).

This is done using slightly different mechanisms for each of LoadInfo and
nsDocShellLoadState, and will be used in the next part to validate document
loads based on the RemoteType responsible for the load.
For subresource loads, the TriggeringRemoteType is fairly straightforward - it
is the process which created the channel. We can handle this by getting the
current remote type when creating the channel, and then using the remote type
of the sending process when receiving the LoadInfo over IPC to either replace
the triggering remote type, or validate it.
For document loads, the situation is a bit more complex, as there are at least
3 (potentially-)different processes responsible for different parts of the
navigation:
1. The "Triggering Process" is the process which provided the URI to load.
This is also the process which provides the Triggering Principal. This is
the process being tracked in this patch.
2. The "Loading Process" is the process which actually creates the channel and
starts the load. This may be the same as the triggering process, or may be
a different process starting the navigation on behalf of the triggering
process. In general this is the process hosting the current docshell,
though it may be the parent process in the case of parent-initiated loads.
3. The "Final Process" is the process which receives the response and renders
the final document. This isn't known at channel creation time, and is
determined by the result principal and process isolation policy.
This change uses a serializer and special field on nsDocShellLoadState to track
the "Triggering Process" for the load, even as the load state is serialized
between processes by tracking which loads were sent into which content
processes, and matching them up when the parent process sees them again. The
information is then copied into the LoadInfo before configuring the real
channel, so it can be used for security checks.
The "Triggering Process" is overridden to be the parent process for history
loads, as history loads are often started in processes which wouldn't normally
be able to navigate to those pages. This is OK thanks to the changes in part 1
which validate history loads against the real session history when SHIP is
enabled.

Previously, we tracked UnstrippedURI on the nsDocShellLoadState and LoadInfo,
and manually filled it in to match the previous load when doing a
LOAD_CMD_RELOAD in nsDocShell. It is more consistent with other load types to
instead store the information in the load state, allowing it to be handled
consistently for reloads and other history operations.
Unfortunately, this patch has some extra complexity right now, as it needs to
support both SHIP and non-SHIP session history. This should disappear in the
future when we switch to using exclusively SHIP.

The devtools test reloads a page twice in a row and depending on timing it isn't guaranteed that it leads to two requests anymore.
That test seems to fail on debug builds every now and then. The test itself expects 1 or more requests, but then assumes later that there
are at least 2.

Following a suggestion from :mkmelin, this seems like an optimal solution: the overriding/duplication in m-c is removed, and all users get a more powerful default choice that they're still able to override with their own, should they so wish.
For clarity and to match other `about:` pages, the shared code is placed under `toolkit/content/`, and all content under `docshell/resources/` is removed.

If we don't preserve the precursor principal in this case, we'll end up
doing an unnecessary process switch in some cases, which lead to a
test failure.
This patch also cleans up some logic around the first party origin
attribute with null principals, as the logic was only used in one place
and generally added some unnecessary complexity to NullPrincipal
itself.
