Current window state in the sessionstore system includes `sizeMode` which can be "normal", "minimized", "maximized". However, the OS also remembers whether the window was "normal" or "maximized" before minimization to restore it appropriately. With this fix, sessionstore does likewise.

* New topLevel loads get the nsILoadInfo.openerPolicy of the current top level document
* Parsing the Cross-Opener-Origin-Policy of a channel will update mLoadInfo.openerPolicy and this value will get propagated to the child process.
* SessionStore now checks nsIHttpChannel.hasCrossOriginOpenerPolicyMismatch (preffed off) and performs a process switch if needed

Issues were occuring where a process swap would be decided upon during
on-examine-response, but before the swap could be handled by the
channel, the channel was redirected.
This new code takes the mildly hacky approach of simply using a separate
observer notification which is fired at the correct time. A better
solution may be to use a dedicated service for responding to these
events, however that was not implemented for this initial patch.

This will only happen if the pref is enabled, and works through the existing
mechanism for process switching loads. It should enable POST data to be
preserved when performing a process switch, for example when submitting
a form on a file:// or moz-extension:// URI to a http:// URI.

Since about:newtab now runs in the privileged content process, SessionStore
will attempt restore the tab's content whenever we perform a process switch.
This causes the tab's content area to be focused. We will add a condition to
prevent focusing on the tab's content area.
This patch also focuses on the URL bar first before opening a new tab to avoid
flickering.

Now that we have moved some about: pages to the privileged content process,
opening these URLs from a non-privileged content process will trigger SessionStore
to restore the tab state due to a process flip. We will set favicons for these
URLs earlier to avoid flickering and improve perceived performance.
This patch also prevents the spinner whenever a page with a local about: URI
(about:blank and about: pages that resolve to jar:// or file:// URIs) is
loaded from a process that the URI cannot load in (e.g. loading about:newtab
in the web content process), as well as during tab duplication or session
restoration for such local about: URIs.
Before this patch, there were additional frames when opening a new window, causing
browser/base/content/test/performance/browser_windowopen.js to fail. This patch
will reduce the number of frames when opening a new window.
