Summary:
This moves the load of favicons into the content process. We use the same logic
for finding favicons (based on waiting until none have shown up for a short
time) but then load the favicon and convert it to a data uri which we then
dispatch to the parent process. Along the way this fixes asssociating the load
with the tab for WebExtension and devtools, fixes CSP usage for the load, fixes
expiry detection of the favicon and stops us from loading the same resource
twice.
This change also merges the prefs browser.chrome.site_icons and
browser.chrome.favicons leaving just the former controlling favicon loading. It
adds the pref browser.chrome.guess_favicon to allow disabling guessing where
a favicon might be located for a site (at <hostname>/favicon.ico). This is
mainly to allow disabling this in tests where those additional yet automatic
requests are uninteresting for the test.
There are multiple clean-ups that can follow this but this is a first step along
that path.

Rename TOTAL_DOCGROUPS_PER_TABGROUP to
TOTAL_HTTP_DOCGROUPS_PER_TABGROUP, that collects telemetry for all
docgroups per tabgroup, but only for uris with http:// or https://
schemes.
Rename ACTIVE_DOCGROUPS_PER_TABGROUP to
ACTIVE_HTTP_DOCGROUPS_PER_TABGROUP, that collects telemetry for active
docgroups per tabgroup, but only for uris with http:// or https://
schemes.
This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

Sometimes when video is playing, a preroll ad plays, and that may be in a cross
origin iframe. If autoplay media is disabled, we require a user gesture in a
document before playback in that document is permitted, and we require each
origin to be gesture activated separately. So in the cross origin preroll video
add case, then the user will have to click once to unblock playback for the
cross origin ad, and then once the preroll ad finishes, the user will have to
click again to activate playback of the same origin content video.
This is a bad user experience.
So we should instead make gesture activation propagate up the doc tree
irrespective of crossing origins. This way, when the user clicks to activate,
all documents in that tab are also also effectively gesture activated, and so
can autoplay.

This was a memory-saving optimization introduced as part of dependencies for bug
686875, but a more general system landed in bug 77999 for Gecko and
https://github.com/servo/servo/pull/18509 for Servo.
So now it's probably even a bit of a pessimization (though probably not huge),
and given this causes bugs like bug 1462742, bug 1157592, and bug 1468145, and
fishiness like the one pointed out in this bug, we may as well remove it.
The performance impact of having to lookup through more rules should be minimal
given the bloom filter and the rule hash optimizations.
This makes me wonder whether we could remove the whole concept of on-demand UA
sheets, since they've caused pain, for example, when the frontend people try
loading <svg>s from NAC (since that triggers sheet loading from frame
construction, which is not good). I'm not concerned about loading mathml.css and
svg.css everywhere, though xul.css may not be as doable since it adds a bunch of
attribute-dependent selectors. Though on the other hand I asserted in the
xul.css code and we don't load it in content with <video> / <input
type="date/time/etc"> and such, afaict, so maybe now that legacy addons are gone
we can remove that sheet from content processes altogether.

We relied already in DestroyContent not fiddling with child lists, so added
assertions to that effect.
The GetChildCount comment in UnbindSubtree looks outdated (there's no
GetChildCount impl which does anything like creating children).

The underlying issue here is that the rule that makes the custom content
container abspos is in ua.css, and we don't load that for SVG documents.
Similarly, this fixes all the markers and such, that would be inline because of
the lack of html.css etc.
This fixes the root cause of bug 1462742, as well, so I added a few assertions
that should replace the wallpaper there. The reason we're guaranteed to be oof
is because top-layer implies that via StyleAdjuster::adjust_for_top_layer.
As an aside, the fact that AccessibleCaret calls into InsertAnonymousContent
from frame construction makes me extremely nervous, but it already does all sort
of other pretty nasty stuff... I'll file and fix.

This patch splits FontTableURI and BlobURL in 2 classes:
FontTableURIProtocolHandler and BlobURLProtocolHandler
both under mozilla::dom.
It also removes a memory reporter because that report is already covered by the
BlobURL one.
This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

Add ACTIVE_DOCGROUPS_PER_TABGROUP and TOTAL_DOCGROUPS_PER_TABGROUP to
collect data on how many docgroups a tabgroup has whenever a top level
content document associated with that tabgroup would hide. This gives
a fairly accurate estimate of the number of docgroups a site
uses. TOTAL_* counts all docgroups while ACTIVE_* only count docgroups
with at least one document not in the bfcache.
Previously, with early first paint enabled, nsXULWindow incorrectly loaded the
persisted window settings from about:blank and would only load them once.
Instead, load the settings before starting layout.

There are two issues being fixed here. First, if DisallowBFCaching is called
before CanSavePresentation, we should really return false from
CanSavePresentation. Otherwise we'll end up doing a bunch of state-capturing
work for no reason.
Second, if DisallowBFCaching is called between CanSavePresentation and
nsDocumentViewer::Destroy, we need to actually tear down the viewer state.
What we do right now is avoid putting the viewer into the SHEntry, but still
not tear down its presshell and so forth, which leads to asserts in
~nsDocumentViewer when this case is hit.
Now that BeginUpdate is useless for the UPDATE_STYLE case, we don't need the
update mechanism at all. Just ensure that ApplicableStylesChanged is called on
the pres shell via the relevant RuleChanged, etc. notifications.
There's a big hidden gotcha here. nsIDocument::BeginUpdate does put a script
blocker on the stack for these updates. However it's not needed, since no script
can run during these notifications (only the stylesheet events we post for
devtools, but those use AsyncEventDispatcher and PostDOMEvents, so they don't
try to run immediately).
nsIDocument::BeginUpdate also does XBL binding attached queue stuff, but we
can't change bindings during these notifications anyway, so it also doesn't
matter.
