Push pointer event pref before testing test_assign_event_data.html and remove redundant assertions since the pushed pref will be restore after testing.

It's easy to mess up the scoping so that (a) the label is pushed and then
immediately popped, and/or (b) the string doesn't live long enough. It's also
easy to do a utf16-to-utf8 conversion unnecessarily when the profiler is
inactive.
This patch splits that macro into three new ones that are harder to mess up.
- AUTO_PROFILER_LABEL_DYNAMIC_CSTR: same as current.
- AUTO_PROFILER_LABEL_DYNAMIC_NSCSTRING: for nsCStrings.
- AUTO_PROFILER_LABEL_DYNAMIC_LOSSY_NSSTRING: for nsStrings.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

By returning true from WebRenderLayerManager::EndEmptyTransaction, we
avoid doing a full paint in cases where the caller decides an empty
transaction would be sufficient. WebRenderLayerManager already rejects
attempts to set some forms of empty-transaction data (specifically
transform and scroll offset updates). This means that we will never get
a call to EndEmptyTransaction where the caller is expecting a transform
or scroll offset update to be sent over to the compositor. So if we have an
implementation of EndEmptyTransaction that ignores that data, it will not
break expectations.
There is still one piece of information that WebRenderLayerManager
doesn't reject in this manner, the APZ focus state. That is, if the
layout code sets a pending APZ focus state on the WRLM, followed by a
all to EndEmptyTransaction, it expects the focus state to get propagated
to the compositor. This patch makes sure that it does happen by using
the new API added in the previous patch.

Revise the pointer event implementation, includes
- Revise the implementation to fetch preference values.
- Separate the logic to get the pointer capturing frame to PointerEventHandler.

This isn't a super essential feature, and is just a change to try to bring us in
line with chromium and the spec. As this has apparent web compat issues, and
DataTransfer is a hard to test area, this patch moves the changes behind a pref,
which we can come back to turning on after we ship 57.
This ensures that, if the touch event is over a scrollbar thumb and
makes it into nsSliderFrame::StartAPZDrag(), nsSliderFrame knows
that the event went through APZ and that therefore APZ will handle
the drag.

These functions are now dead code. And really, they were already dead code
even before this patch-stack -- they were only called in never-evaluated
(and now-deleted) #else clauses.

With previous change, KeyboardEvent is dispatched even when invisible window
has focus. However, nsRootWindow::GetControllerForCommand() returns controller
for focused window even when the window is invisible because it uses
nsFocusManager::GetFocusedDescendant() to retrieve focused window.
Perhaps, we can assume that users won't expect to do something with invisible
window when they type some keys. Then, nsRootWindow::GetControllerForCommand()
should return controller for visible ancestor window if focused window is
invisible.
This patch makes nsFocusManager::GetFocusedDescendant() can return only visible
descendants. However, it already has a bool argument. Therefore, it should
have a flag instead of adding new flag. Most changes of this patch is replacing
its callers.
Then, nsRootWindow::GetControllerForCommand() and nsRootWindow::GetControllers()
should have a bool flag if it should return controller(s) for visible window.
This patch adds a bool flag for it. Fortunately, the interface isn't scriptable.
Finally, this patch makes nsXBLPrototypeHandler::DispatchXBLCommand() and
EventStateManager::DoContentCommandEvent() retrieve controller for visible
window since they are always handles user input.

When focused document is invisible, PresShell::HandleEvent() won't dispatch
any events. However, if it's KeyboardEvent, user cannot do anything only with
keyboard. So, in this case, PresShell should retarget keyboard events to
first visible ancestor.

When there is no selection and no focused content, aContent of
nsIPresShell::GetScrollableFrameToScrollForContent() is nullptr. Then, it'll
use root scrollable frame to scroll. However, the root scrollable frame may
be not scrollable. In such case, ancestor document's scrollable frame should
be scrolled instead.

We currently use the aFlags argument of ContentRemoved for two purposes:
(1) To determine when a frame is being removed due to its element being removed
from the DOM, so we reframe its now-possibly-no-longer-suppressed
whitespace siblings as needed.
In other cases, our ContentRemoved call will be followed by a
ContentInserted call, which will end up doing AddTextItemIfNeeded() to
generate the relevant textframes if they're necessary.
Since we only need to tell apart the "DOM removal" and "anything else"
cases, we don't need to thread the aFlags argument through all the ways
ContentRemoved can call itself (on an ancestor).
All those cases should just be treated as "not DOM removal". In particular,
even if the original call _was_ for a DOM removal, if we convert it to an
ancestor reframe, which will call ContentInserted on the ancestor as well,
we don't need to do anything with text siblings of the ancestor.
(2) To save the frame tree state from DestroyFramesFor, but the frame tree
state is unconditionally captured on RecreateFramesForContent, so we only
need to care about it in the original ContentRemoved call.
Because of that, we can move that to the callsite, patch incoming for that.

This patch splits up the existing "layout/style-sets" measurement into
"layout/gecko-style-sets", or "layout/servo-style-sets/stylist/rule-tree" and
"layout/servo-style-sets/other". (Additional things will be measured under
"layout/servo-style-sets/" later, such as cascade data.)
This requires introducing a new type, ServoStyleSetSizes, for transferring the
multiple measurements from Rust code to C++ code.

For parent process, users may expect the UI is interactable after they saw the
first tab has restored/shown.
So this patch added a new topic "sessionstore-one-or-no-tab-restored" which
represents the parent process has finished a tab restoring. If there is nothing
to restore, it is effectively equal to "sessionstore-windows-restored".
For centent processes, users may expect web content is interactable when the
top-level-content-document has finished loading, which is different from the
parent case.
