This patch implements a per-process cache of parsed stylesheets for
non-inline sheets. The entries are evicted when the document gets
destroyed and there's no other document with the same principal around.
This works fine in practice even when navigating because CC happens
pretty late, but we could add an extra timer if we deem it worth it.
I had to adapt some tests so that they keep passing. They were already
clearing various image / network caches so it seems fine to also clear
this one.
Note that there's a very subtle change in the load data key: We only
miss the cache if the referrer _policy_ is different, not if the
referrer is different. While that is slightly dubious, that is the only
think that makes this effort somewhat worth it. Otherwise stylesheets
would have to be re-fetched if the referrer is different, which
effectively would mean to re-parse it if the document URI is different,
which is bad.
It seems like the network cache only keys on the referrer policy, so it
seems fine to do the same.

One note about this solution: it includes the apz callback transform for the root scroll frame of the root content document, but no other apz callback transform that might be on an ancestor of the select element.

I don't think all this complexity is worth it for having a
marginally-more-realistic testing story. Using the pref just works and we should
do that, I think.

This removes the need for FrameForPointOptions::IsRelativeToLayoutViewport,
and makes sure each call site of these functions indicates whether the
input point/rect is in visual or layout coordinates.
Several call sites were passing in layout coordinates without setting the
IsRelativeToLayoutViewport flag, which this patch corrects.

This "upgrades" various nsLayoutUtils functions which take as inputs
a set of coordinates and a frame that the coordinates are relative to,
to accept a RelativeTo object instead of a frame.
Most of the patch is just dumb propagation, but the few places where
we use an explicit ViewportType::Visual are important. There are
probably a few other places I've overlooked, but this seems to cover
the important ones that come up commonly.
There are undoubtedly other functions into which we can propagate
RelativeTo, in this patch I've propagated it as far as necessary
for my needs in this bug (mainly GetTransformToAncestor() and
GetEventCoordinatesRelativeTo()).

This patch adds support for the capture and replaying of multiple frames
during normal operation of Firefox. Ctrl + Shift + 6 starts capturing
and pressing it again stops capturing. It attempts to capture the minimum
amount of data required to replay a sequence for debugging purposes.
There are several known limitations, particularly surrounding replaying
when transitioning between snapshots of the resource cache. It will
reload the entire document set, causing greater delay between frames.
Should you advance too quickly, it may also panic due to a race between
the current frame still being generated, and the new frame resetting the
resource cache state. These should be resolved with time, and the
current implementation should be workable to at least capture/debug most
animated issues with some effort.
It also adds support for loading dynamic properties which is necessary
for accurate replaying of a captured frame (sequence or individual)
which are in the middle of an animation.

We lifted this restriction because with bug 656036 it makes sense to zoom into a
focused input in a fixed subtree. But this causes undesired panning up.
We could conceivably fix it if needed, but for now preserve the previous
behavior of not panning nor zooming.
Differential Revision: https://phabricator.services.mozilla.com/D69946
The tests don't have a reliable mechanism to wait for a potential zoom
animation to end, leading to flakiness due to a zoom animation form a previous
sub-case interfering with the current sub-case.

This refactoring:
* Removes the "avoid focusing a fixed subtree" condition, because it doesn't
make sense after bug 656036.
* Avoids keeping nsIFrame pointers across calls to ScrollContentIntoView(),
which can flush layout and thus is unsafe.

Now that we have UTF8String in the WebIDL, we can remove quite a few of the
conversions. Do that, and lift the remaining string conversions up as needed.
Also deindent Servo_ComputeColor while touching it.
Most of the remaining copies are because either bug 1606994, or because they're
WebIDL attributes that we still need to serialize back as UTF-16 (bug 1606995).

In particular, the ones where we transcode unconditionally atm (property names
and such).
There are others like cssText getters and setters which are a bit harder,
because I either need to rewrite all our serialization code to work with UTF8
(which is fine, but a lot of work), or teach webidl to have a setter that takes
UTF8String as input but returns DOMString as output (which is at best hacky).

`synthesizePlainDragAndDrop()` synthesizes drag events with `DataTransfer`
object which is set to `DragEvent.dataTransfer` of `dragstart` after starting
drag session explicitly. However, this causes
`EventStateManager::DoDefaltDragStart()` does not initialize `nsIDragService`
instance. Therefore, synthesized drag events cannot work with editor because
`DragEvent::GetMozSourceNode()` returns `nullptr` due to
`nsIDragSession::GetSourceNode()` returning `nullptr`.
On the other hand, synthesized drag events cannot use
`nsIDragService::InvodeDragSession()` normally because of hitting an assertion.
https://searchfox.org/mozilla-central/rev/690e903ef689a4eca335b96bd903580394864a1c/widget/nsBaseDragService.cpp#230-233
This patch does:
- mark drag events caused by synthesized mouse events as "synthesized for tests"
- make `synthesizePlainDragAndDrop()` stop using
`nsIDragService.startDragSession()`
- make `nsBaseDragService` initialize and start session even for synthesized
`dragstart` event
- make `synthesizePlainDragAndDrop()` stop synthesizing drag events with
`DataTransfer` object since it's normal behavior and it'll be initialized
with `nsIDragService::GetDataTransfer()`
- make `nsBaseDragService` store `effectAllowed` for the session only when
it's synthesized session because it's required at initializing synthesized
default `dropEffect` value of `dragenter`, `dragover`, `dragexit` and `drop`
events' `dataTransfer`
- make all tests which use `nsIDragService.startDragSession()` use new
API, `nsIDragService.startDragSessionForTests()` to initialize session's
`effectAllowed` value
- make `EventStateManager::PostHandleEvent()` set drag end point of the test
session to `eDrop` event's screen point
- make `synthesizePlainDragAndDrop()` set drag end point of the session if
it does not synthesize `drop` event because following `endDragSession()`
use it at dispatching `dragend` event on the source element
Additionally, this adds `dumpFunc` new param to `synthesizePlainDragAndDrop()`
because it's really useful to investigate the reason why requesting DnD isn't
performed as expected.

The `setCompositionRecording` API on nsIDOMWindowUtils has been broken up into
two new APIs:
* `startCompositionRecording()`, which starts the composition recorder; and
* `stopCompositionRecording(bool writeToDisk)` which stops the composition
recorder and either returns a Promise that resolves to the collected frames
or returns a Promise that resolves when the frames have been written to disk.
The collected frames are serialized over IPC as part of a Shmem as to not
approach the IPC data transfer limit.

`windowUtils.setCompositionRecording()` now returns a promise that is resolved
when the composition recorder is enabled (if given `true`) or when frames are

to disk begins that is resolved when that process finishes.
