With recent fixes that can properly identify whitelisted domains, whitelisted
domain suffixed, valid known public suffixes, and forcing to visit URI-like
strings that end with a slash, it's time to re-evaluate the URIFixup behavior.
Until now URIFixup considered everything a URI unless it had specific search
characteristics, this patch inverts that behavior.
The scope of this change is to improve the urlbar behavior as the main Search
Access Point, since that's the direction we're moving towards.
This lands with a temporary hidden feature pref browser.fixup.defaultToSearch,
that will be removed once the feature has been released.

This is mostly changes to handle retrieving the security state asynchronously via the parent process, needing lots of async/await additions.
It also removes the docshell mixed content flag checks (which don't seem to be used in code, only tests), which are mostly still covered by checks of the security UI.

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.

Previously we only set some fields as part of WindowGlobalInit, but WindowGlobalParent sets itself as the current window global on the CanonicalBrowsingContext.
This exposes a period of time where only part of the document state was set, and this was observable to consumers.
This makes OnNewDocument only run when there is a new Document for the same WindowGlobal.

This changes the urlbar to always generate a result and then confirm it through
pickResult. This way we obtain a consistent behavior independently from whether
the view has a result or an action like Paste&Go happened.
Before this we used to go through getShortcutOrURIAndPostData, that implements
only a part of the urlbar logic, often causing different behavior depending on
the view state, and thus requiring constant maintenance to sync it up.
In a follow-up bug we will evaluate the complete removal of
getShortcutOrURIAndPostData in favor of direct calls to
UrlbarUtils.getHeuristicResultFor().
This also moves up a bit closer to always pass a final url to the docshell, and
stop trying to do complex URIFixup calls in it. For now we still rely
on its fix-ups for browser.fixup.dns_first_for_single_words, where we pass a
url, and if it's invalid it will instead search. See UrlbarUtils.RESULT_TYPE.URL
handling in pickResult().

Previously we created a new request context id for each LoadGroup, which meant we didn't have a constant value across process switches.
The next patch uses this request context id when creating a new LoadGroup for an nsDocShell, so that all docshell/loadgroups for a BrowsingContext share the same id.

This enables navigating by index in session history go through the
session history in the parent (if enabled with the pref).
If the pref is enabled, then ChildSHistory::Go will send an IPC message
to the parent with the index to navigate to. The parent calls the
existing nsSHistory implementation and starts the loads, and
asynchronously returns the index that we actually navigated to. The
child process then uses that result to update the session history
implementation in the child process (this part is temporary, while we
have session history both in parent and in child). We also make the
parent send an updated length to the child process over IPC, so that
history.length always the length for the implementation in the parent.

This adds a new implementation of nsISHEntry
(mozilla::dom::SessionHistoryEntry). When session history in the parent
is turned on, we'll instantiate the existing nsSHistory in the parent
process, but it will store entries of this new type. The nsSHistory in
the child process will also be instantiated for now, to avoid breaking
too many assumptions, and we try to keep parent and child
implementations in sync.
mozilla::dom::SessionHistoryEntry stores most of its data in a new
structure (mozilla::dom::SessionHistoryInfo) which can be sent over IPC.
When a load starts through the DocumentChannel we create an entry of
this new type for it in the parent process in
DocumentLoadListener::Open. The SessionHistoryInfo for that entry (with
an associated ID) is then sent over IPC in the RedirectToRealChannelArgs
to the process that does the actual load, where we store it in the
nsDocShell in mLoadingEntry (and mLoadingEntryId). The parent process
keeps track of outstanding loading entries in an array (mLoadingEntries)
in the CanonicalBrowsingContext. When a load finishes the nsDocShell
transfers mLoadingEntry into mActiveEntry, and notifies the parent
process through an IPC message (HistoryCommit) with the id of that
entry. The CanonicalBrowsingContext then removes the entry from the
array and stores it in its mActiveEntry, and adds the entry to the
nsSHistory object.
There are a number of things in this patch that are broken, and a lot of
FIXME comments. However, with the pref turned off things should just be
working as before. The goal is to land this first part, and then iterate
on the new implementation until we can switch over.

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

This code should be removed once callers setting customUserAgent are refactored
