These two interfaces contain nostdcall methods, so they should be marked
builtinclass.
There is a JS implementation of nsIWebNavigation in RemoteWebNavigation,
but it appears to never be passed into C++, so it doesn't need to be
made into a "real" implementation of nsIWebNavigation that can be passed
through XPConnect.

Only for top windows because for nested iframes they could get around
this without being noticed by reloading themselves which is not great.

There are two issues in our current setup
1) Input events which are occurring in the same tab are going to be lost
because sync XHR. We have event handling suppression for synx XHR, so input
events are going to be discarded.
2) Input events that are happening in another tab (same process as the
synx XHR tab) are not going to be delayed. This is not correct since
sync XHR should block the Javascript execution.
This patches fixes the above cases for when both TaskController and e10s are
enabled by suspending the InputTaskManager during sync XHR, which
delays the input event handling and keeps the events around.

### Story
While the exisiting top browsing context is replaced, SessionStorage relies on
itself been propagated by SessionStore. However, this has been disabled in
SessionHistory in the parent process.
Therefore, we need to propagate SessionStorage data by propagating
BackgroundSessionStorageManager.
### Notes
This patch assumes that the target top-level browsing context shouldn't have
been registered to BackgroundSessionStorageManager. If this can happen, we will
either need to merge SessionStorage data into it or find a proper (earlier)
place to update sManagers.

I think this allows us to remove TryUsePopupOpeningToken (which is a similar
concept to consuming user activation), and also the ad-hoc <iframe> timing
thing we have from bug 1514547, which should be covered by the user activation
timeout.
Depends on D97640

This should prevent content process crashes when there are
cross-origin descendants with an override set.
There is a slight change in behaviour when an override is set after
a descendant context has previously set one. This shouldn't be a
problem since devtools only wants to expose touch simulation at the
tab level. Additionally this new behaviour is reasonable and would
allow devtools to implement the same semantics by doing the clearing
themselves (if needed).

Before this change, a BrowsingContextGroup would fail to remove itself from a
ContentParent's mGroups table if the process was still launching when the BCG
was destroyed. This was because until the ContentParent had launched, it existed
only in the mHosts table, and not the mSubscribers table, but we only iterated
over the mSubscribers table.
This patch fixes that issue, by iterating over both tables when unsubscribing.
This will cause RemoveBrowsingContextGroup to be called twice on most
ContentParents, but that should not cause issues.

A new `BrowsingContext` field has been added to track the active
browser window for the `:-moz-window-inactive` pseudoclass. This
field takes the place of `nsPIDOMWindowOuter::mIsActive`.
With this change `:-moz-window-inactive` is now fission compatible.

The guess in comment 3 is basically right, here's the relevant bits that
happen in that trace in order:
[content] nsFrameLoaderOwner::ChangeRemotenessCommon:
frame becomes remote for the content process.
[parent] WindowGlobalParent::SendMakeFrameLocal (mIsDocumentLoad=true)
[content] ContentChild::SendCloneDocumentTreeInto
[parent] ContentParent::RecvCloneDocumentTreeInto
[content] WindowGlobalChild::RecvMakeFrameLocal
So basically the source frame we're cloning is mid-switch-to-local:
local already from the parent process POV, but still remote for the
child.
I think ignoring the clone in this case is fine (which will make the
print iframe just about:blank).
I've decided it to handle it in ChangeRemoteness but I could also handle
it in RecvCloneDocumentTreeInto with a check like
if (cp->GetRemoteType() == GetRemoteType())
or such I think. Let me know if you'd prefer that.

When re-enabling the test case blocked by bug 1670933 it became apparent that we were not allowing
session history entries to be marked with user interaction when the SH entry was created by navigation
through a sub-frame. The code that we had for this only covered updating SH entries after pushState etc.,
not adding new entries for document loads.
When SH lives in the child this is easier to manage in nsDocShell, but with Fission it probably makes sense
to move this code to the parent.

This formed the backbone of the previous process switching codepath, and
shouldn't be necessary anymore thanks to DocumentChannel's new codepath.
This also removes the eager process switching logic from frontend's _loadURI, as
it would rarely be taken, unless an invalid URI was entered, already.

The MOZ_MUST_USE macro is defined as clang's and gcc's nonstandard __attribute((warn_unused_result))__. Now that we compile as C++17 by default (bug 1560664), we can replace MOZ_MUST_USE with C++17's standard [[nodiscard]] attribute.

This change removes docshell's `mTouchEventsOverride` and replaces it
with a new `BrowsingContext` field `TouchEventsOverrideInternal`.
All uses of the old field have been replaced and an override should
now work under fission when there are cross-origin descendent frames.
