UI Events declares that keypress event should be fired when the keypress event
causes some text input. However, we're keeping our traditional behavior for
historical reasons because our internal event handlers (including event
handlers of Thunderbird) handles keypress events for any keys. Therefore,
for minimizing the side effect, we should stop kicking keypress event handlers
in the default event group in web content.
This patch adds new pref for enabling the standard behavior in web content.
Additionally, creates WidgetKeyboardEvent::IsInputtingText() for sharing the
check logic between TextEventDispatcher and TextEditor/HTMLEditor.

Currently, access key is handled in EventStateManager::PreHandleEvent() with eKeyPress event, i.e., before dispatching it into the DOM tree, if the access key is registered in EventStateManager. So, the main process does not check if the preceding eKeyDown event is consumed in focused remote process.
When preceding eKeyDown event is consumed in the main process, eKeyPress event won't be dispatched by widget. However, if remote process has focus, it's impossible widget to stop dispatching eKeyPress event because preceding eKeyDown event hasn't been handled in the focused remote process yet. Therefore, main process needs to post eKeyPress event to check if preceding eKeyDown event was consumed. When eKeyPress event is marked as "waiting reply from remote process", TabChild sends it back to the main process only when preceding eKeyDown event wasn't consumed. So, only when eKeyPress event is back to the main process, main process should handle accesskey with it.
This patch makes EventStateManager::PreHandleEvent() check if a remote target has focus before handling accesskey. If a remote process has accesskey and there is an accesskey matching with eKeyPress event, it marks the event as "waiting reply from remote content" and stop propagation in the process.
Finally, when eKeyPress event is sent back to TabParent, TabParent::RecvReplyKeyEvent() calls EventStateManager::HandleAccessKey() before dispatching the reply event into the DOM tree.

EventStateManager checks if every keypress event's modifiers match with access key modifiers which are in prefs. Moving related methods of this to WidgetKeyboardEvent makes EventStateManager simpler and we can hide the NS_MODIFIER_* constants (they may make developers confused between Modifiers of WidgetInputEvent) into WidgetEventImpl.cpp.

Currently, we have 2 bool flags (and optional 2 bool flags with related purpose) for managing propagation state between parent process and remote process. However, it's really complicated. Actually, setting these flags and referring the flags is usually follow explanation.
So, for making simpler, WidgetEvent and BaseEventFlags should have some utility methods for making them as self documented code.
This patch moves WidgetKeyboardEvent::mIsReserved to BaseEventFlags::mIsReservedByChrome. That allows us to manage the cross process event propagation state in same place.

Keyboard scrolling works by first dispatching a key event to the focused element
of the page. It is then caught by a XBL binding put on the chrome event handler of
every window. The XBL binding searches through all of its handlers to find one
that can handle the keyboard event. The matching binding has a command string
which is dispatched to the nsGlobalWindowCommands which dispatches to PresShell
which does the actual scrolling.
To do this asynchronously, we need a representation of the XBL handlers that can
be applied to a KeyboardInput to get a KeyboardAction.
This commit adds KeyboardShortcut for this purpose. KeyboardShortcut is designed
to be compatible with nsXBLPrototypeHandler and to only handle the specific cases
we care about for keyboard scrolling. If a XBL handler runs javascript or does
anything else we cannot handle in an OMT situation, then we create a
dispatch-to-content KeyboardShortcut.

When eKeyPress event is dispatched from TabParent to a remote process, it
should store edit command for all editor types. Then, copied
WidgetKeyboardEvent in the remote process doesn't need to request the edit
commands when its ExecuteEditCommands() is called.
Note that this patch also changes a automated test, browser_bug1316330.js,
that uses nsIDOMWindowUtils.dispatchDOMEventViaPresShell() to dispatch
repeated keyboard events in the tab. However, it should use synthesizeKey()
to emulate everything of native keyboard events and the API can dispatch
repeated keyboard events too. (And the test has a bug. It tries to wait 0.5
sec when every keydown or keypress event. However, it fails since startTime
is never initialized. This patch fixes this bug too.)

Currently, edit commands for native key bindings are stored in widget. This is
stateful and really complicated in content process because it needs to cache
them.
We can make this simpler if we make WidgetKeyboardEvent store edit commands for
the key combination. Then, child process can handle it even if it's delayed
event or it's a nested event.
This patch adds arrays to WidgetKeyboardEvent to store edit commands which are
initialized with nsIWidget::ExecuteNativeKeyBinding() and adds
WidgetKeyboardEvent::ExecuteEditCommands() to execute stored edit commands as
same as nsIWidget::ExecutenativeKeyBinding().

If the remote process is busy or user restarts composition too quickly, there could be 2 or more compositions in ContentCache. For managing such case, ContentCacheInParent should manage the pending composition count which is increased at dispatching eCompositionStart event to the remote process and decreased at receiving eCompositionCommit(AsIs) event from the remote process.

This patch implements some helper methods to log constants related to event handling.
ToString(KeyNameIndex) and ToString(CodeNameIndex) converts the enum itmes to human readable string. They use WidgetKeyboardEvent's helper class which returns Unicode text. Therefore, this need to convert from UTF16 to UTF8. That's the reason why these methods don't return |const char*|.
GetDOMKeyCodeName(uint32_t) returns DOM keycode name if it's defined. Otherwise, returns hexadecimal value. For generating switch-case statement, VirtualKeyCodeList.h shouldn't include ",". Therefore, this patch removes "," from VirtualKeyCodeList.h and append it at defining NS_DEFINE_VK. Additionally, the last item of enum and array should not end with ",". Therefore, this adds dummy last item at each of them. Finally, some of the keyCode values are shared between 2 keys. Therefore, it needs to support NS_DISALLOW_SAME_KEYCODE for switch-case generator. See the comment in the file for more detail.
GetModifiersName(Modifiers) returns all modifier names included in the given value.

Native IME handler may want to query content relative to start of selection (or composition if there is it). Additionally, in e10s mode, insertion point in actual content may be different from the cache in parent. Therefore, in some cases, it does make sense to query content with offset relative to start of selection or composition.
This patch implements it simply and only in non-e10s mode.
Additionally, this fixes a bug of nsQueryContentEventResult::GetOffset() which hasn't been accepted its calls even if the event message is valid (eQueryTextContent, eQueryTextRect and eQueryCaretRect).

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.

If a plugin process posts native key events to the widget, it needs to check if the key combination is reserved by chrome because if it's reserved by chrome, the reserved shortcut key handler should be executed and the event shouldn't be handled by the focused plugin.
This patches add eKeyDownOnPlugin and eKeyUpOnPlugin. nsXBLWindowKeyHandler will listen to them and handle them as normal keydown and keypress or keyup event. Note that these events won't be fired on content in the default event group and won't be sent to the remote process.
