Some extensions want to implement about: pages and we want those pages to be loaded in the extension process, not in the web content process, so that:
1) a compromised web process won't get access to the about: page content
2) the extension page can use all the APIs that extension pages normally get, instead of only content script APIs.
Post-Fission we will need to know which extension process to choose.

Templated pointer can't match |nullptr|, we should add overloading for

The only caller of `TouchManager::PreHandleEvent()` is
`PresShell::EventHandler::HandleEventWithCurrentEventInfo()` which is guaranteed
that it never handles untrused event by bug 1536353. Therefore, we can make
`PresShell::EventHandler::PrepareToDispatchEvent()` call it instead. That's
better place from the point of view of semantics and making
`PresShell::EventHandler::PrepareToDispatchEvent()` simpler.
Note that this may cause changing the score of a telemetry probe,
"INPUT_EVENT_QUEUED_APZ_TOUCH_MOVE_MS" because it will include the time of
the runtime cost of `TouchManager::PreHandleEvent()` when the event is an
`eTouchMove` event and handled by APZ. However, this was expired in 60.
So, we don't meet any changes with this patch actually.

On some low end GPUs, clip mask rendering can be a significant
GPU cost. One way to reduce this is to support segment rendering
on more primitive types, to reduce the size of clip masks.
This patch adds support for pictures that have clip masks
to take part in segment rendering. This can significantly
reduce the number of fragments that must be drawn into a clip
mask for off-screen picture surfaces.
In future, WR can take advantage of segment rendering to use
clip mask shaders that handle only a single corner at a time.
This will be a further significant performance win to clip mask
render time.

Adds a pref to turn off WebRTC RTCP reception for tests, and an associated mochitest.
Once fixed the RTCP regression should cause the mochitest to unexpectedly pass

Apparently importing a certificate into the NSS certificate DB is slow enough to
materially impact the time it takes to connect to a site. This patch addresses
this by importing any intermediate certificates we want to cache from verified
connections on a background thread (so the certificate verification thread can
return faster).

Using clang-cl as a preprocessor fails with:
```
In file included from z:\build\build\src\accessible\ipc\win\handler\HandlerData.idl:8:

There's only one place using the NEWEST_IA2_IDL and accompanying
macros, we can just avoid the issue altogether by expanding it manually
(and it's not like the macro buys much, the other arm of the __midl ifdef
has a #include "Accessible2_3.h" that doesn't use the macro either,
presumably for the same reason).

Cue might have negative length because user can set cue's end time via `TextTrackCue`'s API and the spec doesn't have strong restriction that the end time should be equal or larger than the start time of the cue.
As the negative length cue won't be displayed, we have no need to add it to the `other cues`.

According to the spec [1], `current cues` and `other cues` should only contain cues from `hidden` or `showing` text tracks.
In this patch, text track would be responsible to add `current cues` and `other cues` to the cues list by calling `GetCurrentCuesAndOtherCues()`.
If the text track is disabled, then it won't add any cues to the cues list.
In addition, in order to reduce the size of `other cues` (as actually we don't need to process all cues in the `other cues`), we use the time interval to only get the cues which are overlapping with the time interval.
