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.

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.

Make it a synced field on the top browsing context. This handling the
propagation right and is much simpler.
This should fix cases where we don't look at the top level docshell to
figure out if we should suspend media.

When a tab is owning a main controller, which means that the tab is either playing media, or still waiting for media keys in order to control its media again.
In those situations, we should not suspend the tab so that its script can continue to run for playing media or handling the future task for media keys.

sizemode/displaymode media queries only affect a given browsing context
tree so there's no need to propagate the change to images in that case.

With this change SHIP seems to also fix an issue with hashchange event - those are triggered now
more consistently than without SHIP.

When adding a new entry while handling popstate, this would go
throught the paremeterized version of AddPendingHistoryChange, which
doesn't re-compute length which would result in an error in
history.length.

This adds a rate limit to methods and setters of the History and Location
for non-system callers.
The rate limit is counted per BrowsingContext and can be controlled by prefs.
This patch is based on the original rate limit patch by :freesamael.

This requires adding the flag as a synced field on the BrowsingContext, and
checking it in a few more places. Attempts to open a new window in this racy
manner will now raise an exception.
This should avoid the issue from bug 1658854 by blocking the buggy attempts to
load before the nested event loop has been exited.

The race occurs when the parent changes the owner process for a BC, but the
child does not know about it and proceeds to call SetCurrentInnerWindowId on a
BC it no longer owns. To fix this, in child process, whenever we call
SetCurrentInnerWindowId on a BC, check that the BC is in process and that the
docshell has not been notified about an upcoming process change.

This patch enables sandboxed srcdoc loads to take place via DocumentChannel,
and adds mechanisms for enabling unsandboxed ones.
Both unsandboxed srcdoc, and in subsequent patches, about:blank, loads require
that the triggering principal and the principal to inherit point to the same
instance if the load takes place in the same process as where we are inheriting
those principals from. We save those principals on a target browsing context before
we load the URI, and later, when we are deserializing LoadInfoArgs into
LoadInfo in the content process, we retrieve the saved principals if the
current load identifier of the target BC matches the load identifier saved
along with the principals.
We also need to make sure that during a process switch for about:srcdoc load,
we don't use the original URI for about:srcdoc to determine the remote type and
instead we use channel's result principal.
