In practice this is an easy fix, just clear the icon when the page first changes
to a new URL. In practice that breaks our hack for setting an early favicon for
certain in-content pages so we have to workaround that somewhat.
Differential Revision: https://phabricator.services.mozilla.com/D1909
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.

These probes will register and record (for the duration of the study only):
* When a tab opens.
* When a tab closes.
* When a tab is selected.

To avoid a flash of stale content in the event of a slow tab
switch, we need to make sure we remove a tab from the cache if
its location changes while it's in the background.

We maintain a simple LRU cache of tab layers by setting their
docShellIsActive = false with preserveLayers(true). Once they
are pushed out of the cache by more recently used tabs, their
layers are discarded.
Luckily most of the complexity of this could be contained in
the AsyncTabSwitcher - the one change that had to sit outside of
that was moving the aTab.closing = true earlier in the removeTab
call, so that we could use that information to eagerly evict tabs
from the cache. This was to address a leak in a few tests on try.

This is a backout of Bug 1347791 part 4; 49b533231388.
49b533231388 took the mediaBlocked attribute and stored it in session store,
and caused us to call browser.resumeMedia() or blockMedia() as appropriate
upon restore. We don't want to session restore whether tabs have had delay
playback start unblocked anymore, so remove the code that session stores
that attribute.

Calculate all positioning of the tab during addTab to avoid extraneous events and to provide an accurate tab id during TabOpen.

Manually-implemented QueryInterface functions don't benefit from the
MozQueryInterface optimizaions, and a lot of them are in hot code, and
implement a large number of interfaces.

By setting flex=10000 on the siblings of the toolbox and flex=1 on the toolbox iframe
we ensure that free space gets allocated to the browser contents and that the devtools
toolbox can shrink when the window needs to resize.
