Implementations of nsIEmbeddingSiteWindow and nsIBaseWindow largely

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when the current dimensions are outdated (e.g. immediately reverting a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).

Bug 1805414 will move menu event handling to the DOM.
With that change the current synthetic click behavior of XUL menuitems
breaks. On current central, we rely on nsMenuFrame::HandleEvent not
getting called at all for synthetic clicks, and instead we just fire a
command event synchronously here:
https://searchfox.org/mozilla-central/rev/a0d4f8f112c5c792ae272bf6ce50763ddd23ffa2/dom/xul/nsXULElement.cpp#1071
After my patch the command event is fired properly (potentially
asynchronously too) by the regular menu activation machinery, which is
preferable.
* They fire a command event synchronously (even though on some
platforms like macOS activating a context menu item is async).
* They use a totally different codepath from what a user does.
* They don't deal with native menus, etc.
We have a proper API for this (activateItem) which takes a much more
closer codepath to what users do, requires that the menu is shown, etc.
Use that API instead for testing.
As a benefit, tests now do not need to close the context menu manually
when clicking on a menu item (because we trigger the same code path as
users clicking the menu).

Propagate the ability to pass triggeringRemoteType through the desktop frontend
in various places, such that it is set when using the context menu or content
click handler.
Differential Revision: https://phabricator.services.mozilla.com/D161834
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.
Differential Revision: https://phabricator.services.mozilla.com/D161198
With SHIP, we have a copy of the actual SessionHistoryEntry which is
responsible for a history load locally within the parent process. Using this,
we can validate any session history loads coming from the content process to
ensure that they correspond to actual outstanding history loads.
We can't do this for non-SHIP loads, as session history exists only within the
content process.

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.

By making image loading in <embed> and <object> behave more like when
an <iframe> loads an image, we can make sure that the synthetic
document generated is process switched if the image is cross
origin. This is done by making image loading in nsObjectLoadingContent
follow the document loading path.
We also make sure that we pass the image size back to the embedder
element to not get stuck with the intrinsic size.
To avoid named targeting being able to target these synthetic
documents, as well as showing up in `Window.frames` and being counted
in `Window.length`, we keep a filtered list of non-synthetic browsing
contexts for that use-case.
This feature is controlled by two prefs:
* browser.opaqueResponseBlocking.syntheticBrowsingContext
This triggers the creation of synthetic documents for images loaded
in <object> or embed.
* browser.opaqueResponseBlocking.syntheticBrowsingContext.filter
This turns on the filtering of synthetic browsing contexts in named
targeting, `Window.length` and `Window.frames`.

This patch changes how BrowsingContextGroups track CrossOriginIsolated
status such that it should be more consistently tracked and easier to
assert in the places which depend on it. In the new state of the world,
a flag is stored within the BCG's ID which tracks whether it was
created for cross-origin isolated documents, and that is also checked
when making decisions about how to isolate initial about:blank
documents, and whether to allow certain changes to
CrossOriginOpenerPolicy.
This flag is stashed within the ID, as it needs to be preserved if the
BCG is destroyed and then re-created from the ID (which may be e.g.
round-tripped through JS code). I also considered making the ID be a
string instead, to make it easier to include extra information like
this, and more clear where the information is stored, however :kmag
generally preferred using a bit within the integer ID.
These new assertions should now be less likely to spuriously fail due to
a DocShell disappearing or similar as well, which should help fix the
original issue.
