ChildSHistory.legacySHistory isn't valid for content processes when
session history in the parent is enabled. We try to fix this by either
delegating to the parent by IPC or move the implementation partially
or as a whole to the parent.

This centralizes our print and preview setup in nsGlobalWindowOuter so
that we never re-clone a clone, and so that we reuse the window.open()
codepath to create the browsing context to clone into.
For window.print, for both old print dialog / silent printing and new
print preview UI, we now create a hidden browser (as in with visibility:
collapse, which takes no space but still gets a layout box).
* In the modern UI case, this browser is swapped with the actual print
preview clone, and the UI takes care of removing the browser.
* In the print dialog / silent printing case, the printing code calls
window.close() from nsDocumentViewer::OnDonePrinting().
* We don't need to care about the old print preview UI for this case
because it can't be open from window.print().
We need to fall back to an actual window when there's no
nsIBrowserDOMWindow around for WPT print tests and the like, which don't
have one. That seems fine, we could special-case this code path more if
needed but it doesn't seem worth it.

With fission enabled, walking the docshell tree to find unloaded
parents would stop at the first OOP parent. Instead we now walk
the `BrowsingContext`/`WindowContext` tree. To still check parents
which are OOP, we take advantage of the fact that a parent
`WindowContext` will no longer be the current `WindowContext` if
the parent was unloaded. For in process docshell's we additionally
check the docshell directly.

This removes the diagnostic warnings which used to be logged when the
Large-Allocation header was present, but failed to switch into a
Large-Allocation process. Due to the low adoption of the header, this shouldn't
be too large of a problem, but we can look into re-adding the diagnostics if
needed in the future.
The new codepath no longer performs multiple network requests for
Large-Allocation resources, and now relies on the battle-tested
DocumentLoadListener codepath for process switching.

This removes all docshell nsISecureBrowserUI and mixed content properties, and moves them into CanonicalBrowsingContext/WindowGlobalParent. It makes the mixed content blocker just compute the state for the current load, and then send the results to the parent process, where we update the security state accordingly.
I think we could in the future remove onSecurityChange entirely, and instead just fire an event to the <browser> element notifying it of changes to the queryable securityUI.
Unfortunately we have a lot of existing code that depends on specific ordering between onSecurityChange and onLocationChange, so I had to hook into the RemoteWebProgress implementation in BrowserParent to mimic the same timings.

Reinstate customUserAgent interface for nsIDocShell. This is so it can be used
as a choke-point to catch setting values on docshells which are in the process
of changing process. We don't want to send changes which will be rejected on the
parent side.
This code should be removed once callers setting customUserAgent are refactored
to only occur from parent process.

This value is determined in Parent process and passed down to nsDocShell. Delete
the messages to pass the setting down and set it on the BrowsingContext in the
Parent process.
Refactor the code that determines to opt-out of using global history. Code
inspection determines that windowless browsing contexts want to opt-out as well
as any frame with `disableglobalhistory` attribute set on it.

Both the deprecated `Screen.lockOrientation` and replacement
`ScreenOrientation.lock` APIs have been updated to make use of a new
`OrientationLock` field on the `BrowsingContext`. This replaces the
storage and use of APIs for this on the root docshell.
In the non fission case things should behave the same, as pending
promises for previous calls to `Screen.lockOrientation` will still be
cancelled in process. If there are `BrowsingContext`s in other
processes though, IPC will be sent to the parent, and then each other
child to cancel them. This should be spec compliant as the spec is
already racy with regards to multiple `lockOrientation` calls.
This new implementation has a little extra IPC than the optimal
implementation would since the root `BrowsingContext`s
`OrientationLock` is set using the normal `SyncedContext` machinery,
rather than combining the `AbortOtherOrientationPendingPromises`
message for a single message.
This commit fixes both Bug 1597413 and Bug 1597443.

Implemecurnt a flag `suspendMediaWhenInactive` on the docShell that indicates media in that shell should be suspended when the shell is inactive. Currently, only GeckoView is using this flag.
---
The reason of implementing this flag is because in bug1577890 we remove the old way to suspend/resume the media, and I thought setting docshell to inactive is enough to suspend the media because we already have a mechanism which would suspend/resume media when document becomes inactive/active [1].
However, the active state of document is actually different from what I thought it was. Setting docshell to inactive won't change the document's active state, because that indicates if the document is the current active document for the docshell [2] (docshell can have multiple documents), instead of indicating if the docshell is active or not.
Therefore, we have to add another flag to indicate if the docshell wants to suspend its media when it's inactive, in order to use current mechanism to suspend/resume media.
