This refactoring patch separates the preparation of the fetch event
object from its dispatching, so that consumers would be able to
dispatch the event asynchronously.
Jemalloc 4 purges dirty pages regularly during free() when the ratio of dirty
pages compared to active pages is higher than 1 << lg_dirty_mult. We set
lg_dirty_mult in jemalloc_config to limit RSS usage, but it also has an impact
on performance.
So instead of enforcing a high ratio to force more pages being purged, we keep
jemalloc's default ratio of 8, and force a regular purge of all dirty pages,
after cycle collection.
Keeping jemalloc's default ratio avoids cycle-collection-triggered purge to
have to go through really all dirty pages when there are a lot, in which case
the normal jemalloc purge during free() will already have kicked in. It also
takes care of everything that doesn't run the cycle collector still having
a level of purge, like plugins in the plugin-container.
At the same time, since jemalloc_purge_freed_pages does nothing with jemalloc 4,
repurpose the MEMORY_FREE_PURGED_PAGES_MS telemetry probe to track the time
spent in this cycle-collector-triggered purge.
Per the product discussion, the Notification API should be disabled in
ServiceWorker in release builds for 42 since the UX isn't great [1].
The aim is to release in 44.
Apologies for the code duplication for pref checking in Notification and
ServiceWorkerRegistration. There isn't a easy way to get
ServiceWorkerRegistration's generated binding to include Notification.h without
having an attribute/method that uses Notification.

The semantics of the new attributes are as follows:
* nightlyAndroid only takes effect on Android.
* If both nightlyAndroid and android are specified, nightlyAndroid takes
* precedence.
These two rules allow us to check for the current situation.
The particular warning here was complaining about an unsafe comparison between
a uint32_t and a bool.

Get rid of having users dispatch control runnables. It was error prone and
required too much reasoning. It was also possible to end up in a state where
callers would dispatch a WorkerRunnable, which would succeed, so they would not
dispatch a WorkerControlRunnable. Then the worker would stop Running,
canceling and releasing the runnable leading to releasing the proxy in an
unclean state. Instead, we AddRef() and add the feature and remove the feature
and Release() on Notify(). If callers successfully run a WorkerRunnable they
clean the proxy. If not, the proxy stays alive until the worker switches to
Canceling state.

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in

This commit implements the following changes to get registration.https.html working.
1) Fail with NS_ERROR_DOM_SECURITY_ERR where the spec requires it.
2) Propagate JSExnType to ServiceWorkerManager::HandleError() so that a JS
exception object with the correct .name can be created.
3) Fail with security error on redirect failure.
4) Check fetched script's mimetype.
5) Add missing python server files for web-platform-tests.
6) Update web-platform-tests expected data.
7) Several tests have been changed to use TypeError or more appropriate JS
errors based on my reading of the spec.

"If response is a network error or response's status is not in the range 200 to 299, then:

Right now, synthetic Responses did not have a valid channel info. When these
were saved in the Cache, and then restored, the restored Response did have
a ChannelInfo, but that ChannelInfo did not have a valid security info.
Passing this to respondWith() then caused the interception to fail.
This patch modifies Response::Constructor() to initialize its ChannelInfo from
the global. ChannelInfo can now initialize itself from a nsIDocument. All
workers now store their ChannelInfo on the WorkerLoadInfo.

This is motivated by three separate but related problems:
1. Our concept of recursion depth is broken for things that run from AfterProcessNextEvent observers (e.g. Promises). We decrement the recursionDepth counter before firing observers, so a Promise callback running at the lowest event loop depth has a recursion depth of 0 (whereas a regular nsIRunnable would be 1). This is a problem because it's impossible to distinguish a Promise running after a sync XHR's onreadystatechange handler from a top-level event (since the former runs with depth 2 - 1 = 1, and the latter runs with just 1).
2. The nsIThreadObserver mechanism that is used by a lot of code to run "after" the current event is a poor fit for anything that runs script. First, the order the observers fire in is the order they were added, not anything fixed by spec. Additionally, running script can cause the event loop to spin, which is a big source of pain here (bholley has some nasty bug caused by this).
3. We run Promises from different points in the code for workers and main thread. The latter runs from XPConnect's nsIThreadObserver callbacks, while the former runs from a hardcoded call to run Promises in the worker event loop. What workers do is particularly problematic because it means we can't get the right recursion depth no matter what we do to nsThread.
The solve this, this patch does the following:
1. Consolidate some handling of microtasks and all handling of stable state from appshell and WorkerPrivate into CycleCollectedJSRuntime.
2. Make the recursionDepth counter only available to CycleCollectedJSRuntime (and its consumers) and remove it from the nsIThreadInternal and nsIThreadObserver APIs.
3. Adjust the recursionDepth counter so that microtasks run with the recursionDepth of the task they are associated with.
4. Introduce the concept of metastable state to replace appshell's RunBeforeNextEvent. Metastable state is reached after every microtask or task is completed. This provides the semantics that bent and I want for IndexedDB, where transactions autocommit at the end of a microtask and do not "spill" from one microtask into a subsequent microtask. This differs from appshell's RunBeforeNextEvent in two ways:
a) It fires between microtasks, which was the motivation for starting this.
b) It no longer ensures that we're at the same event loop depth in the native event queue. bent decided we don't care about this.
5. Reorder stable state to happen after microtasks such as Promises, per HTML. Right now we call the regular thread observers, including appshell, before the main thread observer (XPConnect), so stable state tasks happen before microtasks.
client.focus() now directly uses the DOMServiceWorkerFocusClient event. The
platform popup checking is not available on service workers. Instead each
worker maintains a counter of if it is allowed to interact with windows. This
counter is currently only incremented by the notificationclick event and
dropped after the event has been dispatched.
Since acquiring a client is an async operation most service workers will
perform in notificationclick, an additional extension is granted after the event
during which the service worker may focus a client. This extension is only granted
if the script invokes NotificationEvent.waitUntil() at which point the timer begins.
The extension is terminated when the Promise passed to waitUntil() is fulfilled, or
the timer expires, whichever comes first.

This works because KeepAliveHandler only holds nsMainThreadPtrHolder<> which is
itself thread safe. It has assertions that the PromiseNativeHandler overrides
are only called on the worker and these assertions are satisfied.

Refactor creation and show dispatch so Notification constructor and showNotification can use it.
Move persistence to ShowInternal.
NotificationStorage calls callback async even when fetching from cache, simply to have similar semantics.
Calls to Notification::Get() are performed async since persistence is now async after being moved to ShowInternal().
Both are in accordance with the spec where the "append to list of notifications" operation is performed in the "show steps" which are performed in parallel from API invocations.
