There is no reason to keep StartBatchChanges and EndBatchChanges in nsISelectionPrivate since this is noscript method. And if moving it to Selection, we can remove virtual keyword.

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.

Similar to Selection::Collapse(), if mCachedRange is available,
Selection::SetBaseAndExtent() should use it rather than creating new nsRange
instance.
Then, it can reduce the allocation cost and may reduce some other cost, e.g.,
adding it to mutation observer.

When setting value of <input type="text">, nsTextEditorState removes all
ranges of normal selection first. Then, TextEditor sets the value. Finally,
TextEditor collapses the selection at the end of the text.
In bug 1386471, we got that there are some problems to remove the call of
Selection::RemoveAllRanges() in nsTextEditorState. Therefore, we need another
approach to improve Selection::Collapse().
The approach of this patch is, when removing all ranges from normal selection,
Selection can cache an nsRange instance if there is an instance which is not
referenced from other than the Selection (i.e., it'll be removed when
Selection::Clear() is called). Then, Selection::Collapse() can reuse it. With
this fix, Selection::Collapse() can reduce allocation cost and may reduce some
other cost like adding it to mutation observer.
However, keeping nsRange instance may cause increasing mutation observer's cost
since nsRange will be adjusted its start node/offset and end node/offset with
mutation observer to guarantee that the range is always valid. So, we can
cache such range only when the caller (or its callee) will set selection range
later. Therefore, this patch adds Selection::RemoveAllRangesTemporarily()
and make only nsTextEditorState::SetValue() and
ContentEventHandler::OnSelectionEvent() use it.

There is no reason that SetTextRangeStyle is defined at nsISelectionPrivate. Also, SetTextRangeStyle isn't scriptable, and is called from CompositionTransaction::SetIMESelection only. So we should move this to Selection.

When enabling lazy frame construction, whitespace only node might not have frame. So editor/libeditor/tests/test_bug1315065.html is failure because nsFrameSelection::MoveCaret returns error since focus node is whitespace only node that has no frame.
So if focus node is whitespace only, we should promote to parent to get primary frame then try again.

nsContentUtils::GetHTMLEditor() currently returns nsIEditor* since editor of doc shell may be any type of editors such as TextEditor or editor object which is implemented by JS. However, nsIEditor is now a builtin class. So, it can return HTMLEditor.

This matches the spec and Chrome, and seems to bring us closer to Edge
and WebKit as well. It also matches our own behavior for addRange(),
which was changed in bug 1341137.
For collapse and selectAllChildren, we match the tests and browsers, but
the spec is incorrect at the time of this writing:
https://github.com/w3c/selection-api/pull/86
The removeAllRanges test hadn't been updated for the spec change.

When range is selected table element, Selection.addRange uses nsFrameSelection. If frame isn't constructed yet, addRange throws NS_ERROR_FAILURE even if table element isn't editable element.
When getting nsITableCellLayout, we should flush frame to construct cell frame.

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.

Web standards use "Container" instead of "Parent". So, nsRange shouldn't use "Parent" for its members and methods.
