Converts dom.animations.offscreen-throttling to a static pref and removes the static function used to create the varcache pref.

Support hiding slices to better understand what's on which layer,
and to hide UI when not relevant.
Requires using a HTTP server due to cross-scripting.

The sessionType getter in SessionStartup sets its internal state if there isn't already one. Since the willCheckDefaultBrowser call added in bug 1622195 happens very early, SessionStartup isn't initialized yet so its state is set to "never restore".

This patch extends shared memory freezing to support the use case where
the parent process retains write access for incremental updates, while
other processes receive read-only access.
Note that, while some OSes allow independent read-only and read/write
capabilities for the same object, all we have on Android is an operation
that prevents future write mappings. Therefore, this allows an existing
writeable mapping to be retained, but if that is unmapped then even the
parent process can't re-create it.
As with freezing, the read-only restriction may not be enforceable if
the recipient process isn't adequately sandboxed (e.g., on Linux, if it
can use /proc/self/fd to reopen the inode for writing).

By and large, this change accomplishes two things:
1. Run db.close() in finally clauses so that even if db access fails, we close
our connections. It also tries to avoid waiting on other, non-DB operations
before calling close, to avoid the DB connection needlessly hanging around.
2. Intercept all async database operations from the remote settings client to
kinto and ensuring they complete before the end of `profile-before-change`.
Any operations started after Services.startup.isShuttingDown (so after
quit/restart is initiated by the user) will throw. Operations started
beforehand are put in a set of operations, and remove themselves once
complete. We AsyncShutdown block on that set of operations completing.

Use finer granularity for some reftest/mochitest SCHEDULES.exclusive entries,
so that reftest-plain does not run when only crashtests are modified, and
vice versa; similarly, break up mochitest into mochitest/browser-chrome/chrome/
a11y. Use schedules-component instead of category.

Evaluating `document.open` + `write` + `close` triggers the `readyState`
to change to "loading". Puppeteer, for example, relies on a seeing an
"init" life cycle event in that case for their `Page.setContent` method.
Also move "Page.loadEventFired" to be triggered by an actual "load"
instead of "pagehide", which we don't see after a `document.write`.

We still need it for Android < 6.0 (API 23) because otherwise we don't
have a way to hook up mozalloc.

Moving the trace point for messages to the inner loop allow understanding what
pages are doing better (if they are creating lots of nodes or changing lots of
params, etc.). Also, it is important to be able to characterize `onmessage`
calls.
Having two tracepoints under `ProcessBlockOnPorts` allows gauging the buffer
preparation overhead. vs just the page's processing code.

the code was left...
