This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

This commit adds a paint worker thread pool to PaintThread, and dispatches
tiled paints to it. The thread pool is only created if tiling is enabled,
and its size is set by 'layers.omtp.paint-workers' and defaults to 1. If
-1 is specified, it will be sized to 'max((cpu_cores * 3) / 4, 1)'.
The one tricky part of dispatching tiled paints to a thread pool is the
AsyncEndLayerTransaction message that must execute once all paints are
finished. Previously, this runnable would be queued after all the paints
had been queued, ensuring it would be run after they had all completed.
With a thread pool, there is no guarantee. Instead this commit, uses
a flag on CompositorBridgeChild to signify whether all of the paints
have been queued ('mOutstandingAsyncEndLayerTransaction'), and after
every tiled paint it is examined to see if that paint was the last
paint, and if it is to run AsyncEndLayerTransaction. In addition,
if the async paints complete before we even mark the end of the
layer transaction, we queue it like normal.
The profiler markers are also complicated by using a thread pool.
I don't know of a great way to keep them working as they are per
thread, so for now I've removed them. I may have been the only
one using them anyway.

Mechanism for restricting pinch zooming when gesture is a two
finger pan. If the pinch span is below a given threshold and the
scroll distance above a given threshold then the zoom level is
maintained to allow for smooth panning with two fingers.

This patch introduces three keyed histograms:
- PREFERENCES_FILE_LOAD_SIZE_B
- PREFERENCES_FILE_LOAD_NUM_PREFS
- PREFERENCES_FILE_LOAD_TIME_US
They are all keyed on the prefs file's name; in my local Linux64 build there
are 13 such files.
Because prefs start up earlier than telemetry, we have to save the measurements
and then pass them to telemetry later.

New content processes get prefs in three ways.
- They read them from greprefs.js, prefs.js and other such files.
- They get sent "early prefs" from the parent process via the command line
(-intPrefs/-boolPrefs/-stringPrefs).
- They get sent "late prefs" from the parent process via IPC message.
(The latter two are necessary for communicating prefs that have been added or
modified in the parent process since the file reading occurred at startup.)
We have some machinery that detects if a late pref is accessed before the late
prefs are set, which is good. But it has a big exception in it; late pref
accesses that occur early via Add*VarCache() and RegisterCallbackAndCall() are
allowed.
This exception was added in bug 1341414. The description of that bug says "We
should change AddBoolVarCache so that it doesn't look at the pref in the
content process until prefs have been received from the parent." Unfortunately,
the patch in that bug added the exception to the checking without changing
Add*VarCache() in the suggested way!
This means it's possible for late prefs to be read early via VarCaches (or
RegisterCallbackAndCall()) when their values are incorrect, which is bad.
Changing Add*VarCache() to delay the reading as bug 1341414 originally
suggested seems difficult. A simpler fix is to just remove the exception in the
checking and extend the early prefs list as necessary. This patch does that,
lengthening the early prefs list from ~210 to ~300. Fortunately, most (all?) of
the added prefs are ints or bools rather than strings, so it doesn't increase
the size of the command line arguments for content processes by too much.

This patch adds following Microsoft's IMEs into the black list which set
their open state to "closed" when input scope is set to IS_URL and sets
input scope for the URL bar to IS_DEFAULT.
Additionally, this adds a new pref to disable this hack because a lot of
users will affect this hack but perhaps, somebody may not like this if
they use tablet.
The new black listed IMEs:
- Microsoft Bopomofo
- Microsoft ChangJie
- Microsoft Phonetic
- Microsoft Quick
- Microsoft New ChangJie
- Microsoft New Phonetic
- Microsoft New Quick
- Microsoft Pinyin
- Microsoft Pinyin New Experience Input Style
- Microsoft Wubi
- Microsoft IME for Korean (except on Win7)
- Microsoft Old Hangul

This patch moves us from using an old pref `general.useragent.locale`combined
with `intl.locale.matchOS` for retrieving user requested locale, to use a new
preference `intl.locale.requested` which stores a list of well-formed BCP47
language tags. If set to empty, the OS locales are used. If not set at all,
default locale is used.
We are also adding a piece of code to migrate from old to new system.

This code is used to detect too-early accesses of prefs in content processes.
The patch makes the following changes.
- New terminology: "early" prefs are those sent via the command line; "late"
prefs are those sent via IPC. Previously the former were "init" prefs and the
latter didn't have a clear name.
- The phase tracking and checking is now almost completely encapsulated within
Preferences.cpp. The only exposure to outside code is via the
AreAllPrefsSetInContentProcess() method, which has a single use.
- The number of states tracked drops from 5 to 3. There's no need to track the
beginning of the pref-setting operations, because we only need to know if
they've finished. (This also avoids the weirdness where we could transition
from END_INIT_PREFS back to BEGIN_INIT_PREFS because of the way -intPrefs,
-boolPrefs and -stringPrefs were parsed separately.)

- Ensure ovr_GetSessionStatus is polled even when a VR presentation
is not active.
- When we fail to initialize an Oculus Session or detect VR hardware,
immediately unload the Oculus Library as we can't poll for ShouldQuit
without a valid Oculus session.
- When we poll ovr_GetSessionStatus, we are now updating the mounted state
in VRDisplayInfo::mIsMounted.
- Added prefs to control enumeration throttling and timeout to release
VR hardware when inactive.
- Some refactoring to make frame loop more understandable and less
brittle.
- When throttling enumeration, we ensure that all other VR apis
also throttle enumeration so that they don't pick up the same device
during throttling.
- Some long functions in VRManager have been broken up and
had their inner-workings documented in more detail.

This was previously limited to 2 per principal and 4 total on

put in place, and the strict limit is causing webcompat issues on

Increase to 8 per principal and 16 in total, bringing us
