On Android, GeckoEditableSupport has already dispatched eKeyDown event and
eKeyUp event even during composition. I.e., the pref which will be enabled
by bug 354358 has already been set to true only on Android.
On the other hand, GeckoEditableSupport does not dispatch them if content
listens to "input", "compositionstart", "compositionupdate" or
"compositionend". So, different from the other platforms, we need additional
pref to make the new behavior behind pref.
Therefore, this patch adds a new pref,
"intl.ime.hack.on_any_apps.fire_key_events_for_composition", to override
existing "intl.ime.hack.on_ime_unaware_apps.fire_key_events_for_composition"
pref. And sets mKeyCode and mKeyNameIndex of the dummy KeyboardEvents to
NS_VK_PROCESSKEY and KEY_NAME_INDEX_Process.

uim is an old IM which uses key snooper to listen to key events rather than
via filter key event API which should be called by applications. It's still
used by Debian 9.x, so, we still need to support this.
Unfortunately, we cannot detect if uim actually uses key snooper because it's
switch by build option of uim. Currently, Debian builds uim as using key
snooper. So, we should assume uim uses key snooper always. On the other
hand, somebody *might* use uim built as not using key snooper, so, let's
decide if uim uses key snooper with new pref,
"intl.ime.hack.uim.using_key_snooper", but its default should be true.
Note that ibus and Fcitx also have the mode to use key snooper (perhaps for
backward compatibility with uim). However, it's not enabled in default
settings and even if it's enabled, Firefox is in whitelist in the default
settings of them for stop using key snooper. Therefore, we don't need to
support key snooper mode for them unless we'll get some requests to
support their key snooping mode.

Adds a PeformanceCounter class that is used in DocGroup and WorkerPrivate
to track runnables execution and dispatch counts.

This code was originally added to debug the frame visibility code.
However it wasn't architected correctly and makes the compositor use an
untrusted layers id from content. Instead of fixing this I'd rather just
delete it, since it's a big pile of code that is basically a debugging
tool that nobody owns anymore.

This retains support for installing unpacked dictionaries, since Hunspell only
supports loading dictionaries from ordinary filesystem paths.
Unpacked extensions are no longer supported on production, except during
development. WebExtensions have no support for the unpacked flag at all, and
specially signed legacy extensions are forbidden from using it, so there's no
point in maintaining support for this install code. Or, more importantly, for
running a nearly complete duplicated set of tests in order to exercise it.

Early AAAA responses might cause issues on hosts without working native
IPv6 connectivity, of course especially notable in TRR-only mode.

We have stopped dispatching "keypress" events for non-printable keys
and key combinations for conforming to UI Events and following the
other browsers.
However, this change hits a serious bugs of Google Docs, Google
Spreadsheets and Gmail. Until they will fix their bugs, we should
take back the traditional behavior for keeping Nightly usable for
any Nightly testers.

Fuzzytime deterministically generates a random midpoint between two clamped values,
and if the unreduced timestamp is above the midpoint, the time is rounded upwards.
This allows safe time jittering to occur, as time will never go backwards on a given
timeline.
It _is_ possible for time to go backwards when comparing different (but related)
timelines, such as a relative timeline in one page (with its own
performance.timeOrigin) and a relative timeline in an iframe or Worker (which
also has its own performance.timeOrigin). This is the same behavior as the 2ms timer
reduction we previously landed; jitter doesn't make this any better or worse.

UI Events declares that keypress event should be fired only when the keydown
sequence produces some characters. For conforming to UI Events and
compatibility with the other browsers, we should stop dispatching keypress
events for non-printable keys.
For getting regression reports, we should enable this new behavior only
on Nightly and early Beta.

image.animated.decode-on-demand.threshold-kb is the maximum size in kB
that the aggregate frames of an animation can use before it starts to
discard already displayed frames, and redecode them as necessary. The
lower it is set to, the less overall memory we will consume at the
expense of execution time for as long as the tab with the animation(s)
above the threshold are kept open.
image.animated.decode-on-demand.batch-size is the minimum number of
frames we want to have buffered ahead of an animation's currently
displayed frame. The decoding will request this number of frames at a
time to maximize use of memory caching. Note that this is related to the
above preference as well; increasing the batch size will in effect raise
what the minimum threshold. This simplifies the logic in patches later
in the series.
For FF59, we disabled WebVR for macOS before allowing it to ride the trains to release. Softvision was unable to verify for QA due to challenges getting a working hardware configuration for macOS VR at SoftVision.
We have since gained approval from the Firefox Release Team to re-enable WebVR for macOS in release for FF60.
Essentially, we need to reverse the changes in bug 1426500 and uplift to FF59/Beta before the next cycle.
This patch disables device sensors except orientation by default.
It implements per-sensor prefs to disable orientation, motion, proximity and ambient light
selectively. The patch also makes the pref checks happen at runtime (versus on process
start) using Preferences::AddBoolVarCache.
The patch also removes the related Event constructors also.
