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.

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.

LazyFC changes the way we initialize browsers in a subtle way which is
important for print preview and PiP.
When creating a print preview browser / PiP, we rely on getting the right
process via _sameProcessAsFrameLoader. This is set very early on the
lifetime of the browser element, after it's upgraded but before its
connectedCallback() calls.
What happens with LazyFC is that we append the browser to the document,
then set its sameProcessAsFrameLoader, then initialize the browser from
connectedCallback(). That calls resetFields() _after_ setting the
_sameProcessAsFrameLoader, which clears it out, not good.
Without LazyFC we initialize it via frame construction, as soon as the
browser is attached to the document, so all ends up working out.
Explicitly avoid clearing this field out if not initialized yet, instead
of the hasOwnProperty check which was for the very same thing, just
about XBL initialization.

Bug 1633938 re-introduced this field to handle full-zoom on RDM without
having to affect the actual content zoom, see related hacks that went
away in this push:
9e6925ea79
But I added it to the browser element constructor, instead of to
resetFields(), which means that it's not properly reset when the
browsing context changes and thus it can get out of sync.
Move it to resetFields(), so that we properly detect that zoom has
changed. An alternative to this is to only use this._fullZoom when in
RDM instead.
This is where a similar field only used for remote browser used to live
before my Fission zoom changes:

We need it to live in BrowsingContext instead of WindowContext, because
we need to preserve the zoom level across same-origin navigation.
It'd be nice if it only lived in the top BC, but that's not possible at
the moment because a lot of tests rely on zooming only iframes. Some of
them can be adjusted for scaling the top instead, but not sure it's
worth it's worth fixing them and moving the zoom to be top-only, as it'd
be a bunch of effort, and the complexity and overhead of propagating the
zoom is not so big.
The print-preview-specific code in nsContentViewer is from before we did
the document cloning setup, and it seems useless. I've tested print
preview scaling before and after my patch and both behave the same.
The rest is just various test changes to use the SpecialPowers APIs or
BrowsingContext as needed instead of directly poking at the content
viewer.
I named the pres context hook RecomputeBrowsingContextDependentData, as
more stuff should move there like overrideDPPX and other media emulation
shenanigans.
I also have some ideas to simplify or even remove ZoomChild and such,
but that's followup work.

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.

When I first added this method last year, I added it in JS, handled from within
SessionStore.jsm, as that was the easiest place to do it. Now that
DocumentLoadListener exists, it makes more sense to handle this logic directly
from within that code.
Many parts of the process switch are still handled by frontend JS, such as
selecting remote types, and performing toplevel process switches.

This patch introduces a new tab modal system prompt type. It can be opened via the nsIPromptService
with a destination BrowsingContext. These tab system prompts overlap slightly with the upper
chrome UI to differentiate them from content prompts (previously called tab prompts).
- Extended nsIPromptService and nsIPrompt to accept 3 types of modal prompts:
- Window prompts
- Tab (system) prompts
- Content prompts (the old tab prompts)
- Removed prompt code from Prompter.jsm, always call PromptParent window actor instead
- Added PromptChild window actor to forward pagehide events to parent actor
- Created additional prompt methods in nsIPromptService to prompt by browsingContext and modalType
- Backwards compatibility is maintained, consumers can still open content prompts calling nsIPrompt with a content window

When searching for the controller for a command in nsWindowRoot::GetControllerForCommand, look for a focused browsing context instead and get the controller through the Controllers actor associated with that browsing context. When a command update occurs in a window in the child process, send the list of commands to the parent process along with the browsing context for that window. The parent will pass this information to the controllers actor. As long as we can get the right currently focused browsing context descendant, we can get the correct command state and invoke commands through the right actor.
