Bug 1441821 - NativeKey shouldn't mark eKeyDown and eKeyPress as "skippable in remote process" if message is not caused by physical key press r=m_kato,smaug Currently, TabChild discards eKeyDown and eKeyPress events which are marked as "repeated" and were dispatched after the latest eKeyDown event comes into the process. However, keyboard layout utils may generate native key events as "repeated" even if each native key is important to input proper text. So, TabChild shouldn't decide if coming keyboard event is skippable only with mIsRepeat. For solving this issue, this patch adds mMaybeSkippableInRemoteProcess to WidgetKeyboardEvent and makes TabChild::SkipRepeatedKeyEvent() check WidgetKeyboardEvent::CanSkipInRemoteProcess() instead. On Windows, there are two ways to generate keyboard input messages. One is using SendMessage() or PostMessage(). The other is SendInput() API. In both ways, utils can make their input as repeated key messages. The former case must be safe for this issue since such utils need to set 31st bit of lParam to 1 explicitly. On the other hand, in the latter case, the utils probably need to append KEYEVENTF_KEYUP into KEYBDINPUT::dwFlags. Otherwise, only first call is treated as non-repeated event. So, when given message does not came from physical key operation, NativeKey should set WidgetKeyboardEvent::mMaybeSkippableInRemoteProcess to false even if WidgetKeyboardEvent::mIsRepeat is true.

Bug 1275914 part.5 Support special selections at handling eQuerySelectedText r=smaug TextComposition needs to query first IME selection. Therefore, we need to add support to query special selection range with eQuerySelectedText. First, WidgetQueryContentEvent::mInput should have mSelectionType which should be initialized with InitForQuerySelectedText() but unfortunately, there is no method for eQuerySelectedText. Therefore, this patch initializes WidgetQueryContentEvent::mInit::mSelectionType with SelectionType::eNormal in its constructor. Next, ContentEventHandler needs to support to handle eQuerySelectedText with special selection types. However, we need to create 2 paths in some cases, one is for normal selection and the other is for special selections because there are no selection ranges may be usual case for special selections but not so for normal selection. Therefore, ContentEventHandler::InitCommon() becomes a little bit more complicated. ContentEventHandler::mSelection and ContentEventHandler::mFirstSelectedRange is initialized with the specified selection type but normal selection type is also necessary to compute the selection root since the selection root is computed from the first selected range which may not be anywhere if its selection type is not normal. Finally, ContentEventHandler::OnQuerySelectedText() returns "there are no selections" as succeeded case in special selection type cases.
