The CSS for page action icons doesn't handle fallback when only one variable
is defined, so for widgets that don't define their icons using CSS, we always
need to provide both.

It looks like TabChild::RenderLayers already does the work of suppressing the displayport,
so all of the suppression and bookkeeping that AsyncTabSwitcher is doing is superfluous
and probably opening us up to weird graphical glitches (like the one associated with this
bug).

We suppress the displayport when requesting a tab or warming it, in order to reduce
the amount of work that the content process needs to do to paint it (we paint just
the displayport area and nothing around it). Afterwards, we unsuppress the displayport
so that we can paint the surrounding areas when scrolling. We normally do this
unsuppression in destroy(), but with tab warming, that unsuppression can happen
after a few seconds (after the tab warming eviction timeout).
This results in users seeing checkerboarding sometimes, where the tab they're looking
at is still suppressing its displayport and waiting for the timeout to complete.
This patch updates the AsyncTabSwitcher to unsuppress the displayport for a tab as
soon as the tab has been switched to, instead of waiting for the timeout.
Out of an abundance of caution, we still unsuppress displayports for tabs that
never get to enter the STATE_LOADED state, although that really should never
happen.

Release is already included in the context as browser info and doesn't need to
be kept as a tag like appBuildId was.

This removes some discovery pane tests which are obsolete. The discovery pane
page that it tests uses InstallTrigger, rather than mozAddonManager as we use
in production, and fails when used with WebExtensions.
The other tests have been updated to use WebExtensions, and some relevant
PopupNotifications bugs have been fixed so that they actually pass.

This adds a policy with the capability of adding search engines, choosing the default search engine, and blocking the installation of new search engines.
Additionally, fixes the messages for errors reported by MainProcessSingleton.addSearchEngine so that the offending URL is printed rather than "[xpconnect wrapped nsIURI]".

nsFrameLoader is on WebIDL bindings, so those QIs are no-ops anyway, unless the given object is no a frameloader to start with.

Reverse the array of node inspection selectors, so that are a bit more naturally
human-readable by starting from the root document and moving inwards.

Since bug 1432509, the warmingTabs WeakSet has had warmed tabs
cleared from it once they have entered STATE_LOADED. This allowed
us to make decisions on tab switch operations based on whether or
not a tab was still being warmed.
This broke our Telemetry, which assumed that warming tabs would
still be in the warmingTabs WeakSet until either requested or
evicted. Now, instead, we look to see whether or not tab warming
is enabled, and whether tabs _could_ have been warmed in order to
add entries to the right buckets.

The transforms for turning an nsIScriptError into a payload that Sentry
understands were getting a bit complex for a single function, so they're
refactored into a list of transform functions that are applied in sequence to
produce the payload. This will make it easier to manage adding new transforms to
the list.
Refactoring this revaled a problem with the test code: it assumed that listeners
for console messages were notified in order of registration (since it used a
temporary listener to determine when the rest of the listeners had been notified
of a message). Changing the async evaluation of the code broke the tests, so
they had to be refactored as well.
Without a way to know when all console listeners have been notified, we can't
assert that a message will not be received by BrowserErrorReporter. We do two
things to get around this:
- Where possible, call `observe` directly on the reporter instance.
- Add constructor params for registering and unregistering listeners so we can
test that logic without relying on messages being received or not.

The amount of computational complexity and garbage array/string/object
generation for each update to a pageAction property went up astronomically
with the migration of WebExtension page actions to the Photon API. This
resulted in non-trivial talos regression when Screenshots attempted to switch
back to the built-in pageAction API.
These changes fix most of the garbage generation, and reduce a lot of the
duplicated work for each update.
