Now, we have an security issue. mCommittedCharsAndModifiers may be initialized with multiple WM_(SYS)CHAR messages. However, if it's generated by odd (or malicious) middleware, mCommittedCharsAndModifiers may be overflown because it has only fixed array. For fixing this issue, first, we should hide the members for making the users not depend on the design of UniCharsAndModifiers.
This patch changes UniCharsAndModifiers to a class and hiding mChars and adding |CharAt() const|.

This patch creates NativeKey::DispatchKeyPressEventsWithRetrievedCharMessages() for dispatching eKeyPress event with mCommittedCharsAndModifiers when it stores following printable WM_(SYS)CHAR messages.
Using loop for dispatching eKeyPress event for every WM_(SYS)CHAR message is wrong because WidgetKeyboardEvent::mKeyValue is initialized with mCommittedCharsAndModifiers and it causes TextEventDispatcher dispatching multiple eKeyPress events at every call of MaybeDispatchKeypressEvents(). Therefore, if mKeyValue is "^^", eKeyPress event is dispatched 4 times --for the first message, eKeyPress events are fired for each "^" and for the second message, eKeyPress events are fired again for each "^"--. Therefore, when it handles WM_(SYS)KEYDOWN and it causes inputting one or more printable characters, it's the easiest way not to use HandleCharMessage().
The new method calls TextEventDispatcher::MaybeDispatchKeypressEvents() only once and it requests to call the callback method with new argument of MaybeDispatchKeypressEvents() when it needs to dispatch 2 or more eKeyPress events. Then, NativeKey::WillDispatchKeyboardEvent() can set each eKeyPress event to raw information of the message and proper modifier state.
With this change, we can dispatch multiple eKeyPress events with retrieved WM_(SYS)CHAR message information rather than retrieved information from active keyboard layout. Therefore, NeedsToHandleWithoutFollowingCharMessages() doesn't return true even when mCommittedCharsAndModifiers stores two or more characters.
FYI: there is a bug in test_keycodes.xul. That is, Alt+'A' of Greek keyboard layout should cause WM_SYSCHAR with a corresponding Greek character but ASCII characters are specified. Therefore, this patch includes the fix of these bugs

First, mCommittedCharsAndModifiers should be initialized with following char messages because the messages could be different from the information of current keyboard layout.
So, this patch guarantees that mCommittedCharsAndModifiers are same as the user expected when there is one or more WM_CHAR or WM_SYSCHAR messages.

Now, NativeKey::HandleCharMessage() has almost same code, one is for dispatching eKeyPress event for non-printable keys or printable keys when one of Alt or Ctrl key is pressed, the other is for printable keys when Alt or Ctrl key is pressed.
The difference of them is, the former block removes Alt state and Ctrl state for handling AltGr key. When AltGr key is pressed, both Alt and Ctrl state are true. However, EditorBase treas keypress events whose altKey or ctrlKey is true as non-printable key event. Therefore, we need to set these modifier state to false when AltGr key is pressed and the key causes some text.
Note that as far as we know, when a key press with AltGr doesn't cause any characters, WM_CHAR isn't generated. Therefore, we don't need to check with complicated logic if the key event is actually inputting a character.

This patch makes NativeKey::HandleCharMessage() stop dispatching eKeyPress event when the message is inputting a control character. NativeKey::HandleCharMessage() runs following cases:
1. WM_KEYDOWN followed by a WM_CHAR message whose wParam is not a control character causes inputting printable characters.
2. WM_CHAR message is received without WM_KEYDOWN message.
So, when HandleCharMessage() is called for a control character, it's unusual case. E.g., another application sends only WM_CHAR message with a control character.
On the other hand, Gecko is the only browser which dispatches "keypress" event even if pressed printable key doesn't cause inputting any characters. And such "keypress" event is used for shortcut key handling and some default action handling. So, even if we stop dispatching eKeyPress event from HandleCharMessage(), it shouldn't affect most users.
Note that this patch does NOT change the behavior when the user inputs a control character with usual keyboard layout such as Ctrl+A of en-US keyboard layout because DispatchKeyPressEventsWithoutCharMessage() dispatches eKeyPress event in such cases.
This patch also adds a lot of tests with Ctrl or Alt state for detecting regressions.

Bug 1305498 - 1. Remove NotificationClient task queue; r=sebastian
Not sure why we needed a task queue for NotificationClient actions. The
actions all go through IPC and are non-blocking, so it's perfectly fine
to perform them off of whatever thread we're on.
Bug 1305498 - 2. Integrate NotificationHandler et al into NotificationCllient; r=sebastian
There's no reason to have NotificationHandler, AppNotificationClient,
and ServiceNotificationClient all separate from the base
NotificationClient class. This patch adds the functionality of
those three classes to NotificationClient.
The notifications hash map is changed from a ConcurrentHashMap to a
regular HashMap with synchronization because I think the use case here
doesn't warrant the added performance and overhead of ConcurrentHashMap.
NotificationService is changed to match the new NotificationClient. Now
the only job for NotificationService is to set a notification as
foreground, rather than to manage all notifications like before.
NotificationHandler, AppNotificationClient, and
ServiceNotificationClient will be removed in a later patch.
Bug 1305498 - 3. Set NotificationListener in GeckoApplication; r=sebastian
Set NotificationListener once in GeckoApplication.onCreate, instead of
spreading it out in GeckoApp, BrowserApp, and GeckoService. This is
possible because there's no longer a distinction between
AppNotificationClient and ServiceNotificationClient in the new,
consolidated NotificationClient.
Bug 1305498 - 4. Remove obsolete notification classes; r=sebastian
Remove AppNotificationClient, ServiceNotificationClient, and
NotificationHandler, now that they've all been replaced by the new,
consolidated NotificationClient.
Bug 1305498 - 5. Use NotificationReceiver for web notification callbacks; r=sebastian
Previously, web notification callbacks went to GeckoApp directly, but
that presented some problems such as not being able to implement the
on-close callback, because we don't want to launch GeckoApp when the
notification is closed by swiping. This patch makes us use
NotificationReceiver for callbacks, and let NotificationReceiver launch
GeckoApp if necessary.
Bug 1305498 - 6. Don't keep notification cookie in native code; r=sebastian
Keep the notification cookie a single location (in the notification
intent itself), and simplify the native notification handling code.
Bug 1305498 - 7. Use NotificationReceiver for persistent notifications; r=sebastian
Currently, persistent notification callbacks go through a different code
path, but it'd be more consistent and correct to let persistent
notification callbacks go through NotificationReceiver as well.
This takes care of some housekeeping work that was missing for
persistent notifications, such as deleting the mNotifications entry when
the notification is closed.
When key combination is reserved by the system, web apps shouldn't be able to consume the key events. In such case, we've decided that we never expose the key events in web contents (including chrome contents). Therefore, NativeKey stops dispatching keyboard events only for Alt+Space.
However, new code of the fix of bug 1300003 always consumes WM_SYSCHAR which follows WM_SYSKEYDOWN of Alt+Space. This is the cause of bug 1305943.
For fixing this bug, NativeKey should have a helper method, IsReservedBySystem(), and when it returns true, it should do nothing when Handle*Message() is called and should not consume following WM_SYSCHAR messages at handling WM_*KEYDOWN.
Unfortunately, it's impossible to test this regression because nsDOMWindowUtils::SendNativeKeyEvent() may call nsIWidget::SynthesizeNativeKeyEvent() asynchronously. See <https://dxr.mozilla.org/mozilla-central/source/dom/base/nsDOMWindowUtils.cpp#1105-1108>. Therefore, it cannot return if it's consumed.

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*|.

Currently, NativeKey::DispatchPluginEventsAndDiscardsCharMessages() calls nsWindowBase::DispatchPluginEvent() and nsWindowBase::DispatchPluginEvent() does nothing when windowless plugin doesn't have focus. However, this is unclear when other developers read the code of DispatchPluginEventsAndDiscardsCharMessages() and it causes unnecessary virtual calls. So, it should try to dispatch plugin events only when a windowless plugin has focus.

NativeKey removes odd WM_CHAR messages which are caused by ATOK or WXG if the user tries to do "Kakutei-Undo" (meaning "undo the last commit") after dispatching eKeyDown event.
However, NativeKey should remove them from the queue first because there are some problems:
* If focus is moved during dispatching an eKeyDown event, we'll fail to remove the messages from the queue.
* If dispatching eKeyDown advance native event loop due to entering to a modal loop or dosing synchronous XHR, the message pattern is broken before removing the odd messages from the queue.
After removing the odd char messages, NativeKey should store them with mRemovedOddCharMsgs because NativeKey needs to dispatch them to focused windowless plugin.
Note that this patch also fixes a bug of the loop to remove the odd WM_CHAR messages. Old code removes only one WM_CHAR messages, but we need to remove all WM_CHAR messages before WM_KEYUP. This must be a regression.

Unfortunately, MapVirtualKeyEx() doesn't compute ABNT C1's scan code from its virtual keycode, 0xC1. Therefore, NativeKeyCodes.js should specify 0x0056 explicitly. Fortunately, this key in physical keyboard always generates the scan code value with any keyboard layouts. Therefore, this can test new regressions as expected.
FYI: ABNT C1 key is a key in Brazilian keyboard. It's at between "ShiftLeft" and "KeyZ".

On Windows, some keys are called "extended key". Their scan code include 0xE000. For example, Enter key in standard position is 0x001C but Numpad's Enter key is 0xE01C. Unfortunately, both of them cause same virtual keycode value, VK_RETURN. Therefore, currently, nsIDOMWindowUtils.sendNativeKey() can synthesize only one native key event of them (only non-extended key's event). Additionally, MapVirtualKeyEx() API with MAPVK_VK_TO_VSC (even with MAPVK_VK_TO_VSC_EX) don't return extended scancode value as expected.
For solving these issues, we should include scan code value to the virtual keycode value at calling sendNativeKey().
Fortunately, virtual keycode value on Windows is 0 ~ 255 (0x00 ~ 0xFF) but aNativeKeyCode of sendNativeKey() is int32_t. So, we can use upper 16 bit for specifying scan code.
This patch explicitly specifies scan code value at defining WIN_VK_* in NativeKeyCodes.js. Additionally, this patch duplicates native virtual keycode definition for Home, End, Insert, Delete, PageUp, PageDown, ArrowUp, ArrowLeft, ArrowDown, ArrowRight and Enter as WIN_VK_* and WIN_VK_NUMPAD_*. This makes automated tests can specify both positions' keys explicitly.
Finally, this patch adds some tests to test_keycodes.xul for testing KeyboardEvent.code value of those keys in both positions.

Separate compiled JARs into GECKOVIEW_JARS and FENNEC_JARS, and run
AnnotationProcessor separately on each set. The GeckoView bindings are
put into widget/android/GeneratedJNI* (same as before), while the
Fennec-specific bindings are put into widget/android/fennec/FennecJNI*.
ibus-pinyin has a bug. When application calls gtk_im_context_reset(), which means selection is changed in application, ibus-pinyin sents a set of composition signals with empty commit string. Therefore, selecting text causes removing it.
For preventing it but not breaking the other IMEs which use surrounding text, we should give up to call gtk_im_context_reset() if IME hasn't retrieved surrounding text after the last selection change. Not having retrieved surrounding text means that the IME doesn't have any cache of contents. Therefore, not calling gtk_im_context_reset() at selection change must be safe for such IMEs.

This patch includes a small memory optimization of using ArrayList and
`volatile int` for storing the pending thumbnails list and pending
width, instead of using LinkedList and AtomicInteger, respectively.
The patch also fixes a possible race condition due to calling
processNextThumbnail outside of a lock. Now it must be called inside a
lock and its name is changed to reflect that.
