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.

DOM Standard defines that offset of Range is unsigned long. However, nsRange uses int32_t to them.
This patch makes nsRange use uint32_t instead. However, this patch does NOT allow to set over INT32_MAX as offset values since a lot of users of nsRange cannot treat the values as over INT32_MAX because a lot of internal APIs take int32_t as offsets.
For easier to search such points, this patch adds static_cast<int32_t> to uint32_t variables when they are used for int32_t arguments.
And note that nsContentUtils::ComparePoints() behaves odd. It accepts negative offset and compares such value with valid offset simply. This patch still uses int32_t offset variables in nsRange::CompareNodeToRange() even though it may be negative value if nsINode::IndexOf() returns -1 because the caller of it depends on this behavior.

Bug 612018 made us flush layout for caret painting which isn't triggered
from anything that can call this code any mode, therefore we can revert
the change from that bug.
When firing an event, check if there is any event in the delayed events queue,
if yes, fire them first to ensure the events are fired in the right order.

Blink and webkit launch focusin after focus and focusout after blur. Despite
this contradiction with the spec, it is best to mirror this new way, as there
is little guidance or existing code to clarify implementation amiguities that
can arise from the spec.
If focus/blur is fired on a window or document, or the event triggers a change
of focus, do not fire the corresponding focusin/focusout. Otherwise, always
fire the corresponding event.
Additionally, add a mochitest and a w3c-platform-test.

This function is an infallible alternative to nsIURI::GetSpec(). It's useful
when it's appropriate to handle a GetSpec() failure with a failure string, e.g.
for log/warning/error messages. It allows code like this:
nsAutoCString spec;
uri->GetSpec(spec);
printf("uri: %s", spec.get());
to be changed to this:
printf("uri: %s", uri->GetSpecOrDefault().get());
This introduces a slight behavioural change. Previously, if GetSpec() failed,
an empty string would be used here. Now, "[nsIURI::GetSpec failed]" will be
produced instead. In most cases this failure string will make for a clearer
log/warning/error message than the empty string.

Bug 1297961 (part 1b) - More GetSpecOrDefault() additions. r=hurley.
I will fold this into part 1 before landing.
