Currently, we use alias NS_VK_* for WidgetKeyboardEvent::mKeyCode. Similarly, we should create alias enum for nsIDOMKeyEvent::DOM_KEY_LOCATION_*. Then, we can reduce the length and avoid to include nsIDOMKeyEvent in some cpp files.

There are still a lot of crash due to failing to get following WM_CHAR message. Almost half of them are, we found a WM_CHAR message but it's gone at removing the message from the queue.
Although, we're still not sure what happen actually. It could be possible if somebody hooks PeekMessage() or something. Then, we can assume that the found message isn't necessary for the user because it must be removed by somebody when it became unnecessary or is handled.
This patch mark a new bool flag, mCharMessageHasGone, as true in such case. Then, NativeKey will dispatch keypress events without following char messages and mark the event as consumed.

NativeKey::GetFollowingCharMessage() may remove a char message which is different from previously found message in the queue because hacky keyboard layout or utility can overwrite the wParam when it's removed from the queue.
Now, we should assume that newer message, i.e., actually removed from the queue, is the expected message by the user. See bug 1336028 comment 0 for the actual scenarios which are collected by crash reports.

Currently, NativeKey::GetFollowingCharMessage() tries 5 times to remove found char message from the queue. It was enough when we found this issue at developing Metrofox.
However, this hack is not enough for some odd keyboard layouts because we see some crash reports which gives up to remove a char message from the queue because 5 WM_NULL messages are returned.
For preventing this crash, we should check if there is the message which is trying to remove from the queue when NativeKey receives WM_NULL. Then, when there is no key message in the queue or next key message becomes non-char message,, NativeKey should dispatch consumed keydown event because we can assume that the key operation may have already been handled or canceled. Otherwise, NativeKey should retry to remove the message again (until 50 times!, it's just enough big magic number, there is no concrete reason).

I think that when PeekMessage(PM_REMOVE) failed to remove a char message but next key message is still a char message, it may be possible that the odd keyboard layout or utility hook only PeekMessage(PM_NOREMOVE) and GetMessage(). If so, we can explain what occurs in this case.
I'm still not sure this fixes the case of bug 1336322 comment 0, but we should try to do this because I don't have better idea.

This patch depends on bug 1336080.
When PeekMessage() fails to remove found char message, NativeKey::GetFollowingCharMessage() tries to check next key message in the queue again. Then, when next key message becomes non-char message, such as WM_KEYDOWN or WM_KEYUP, the char message must be removed by odd keyboard layout or something. Similarly, when next key message is a char message but it's caused by different key, the found char message must be removed by one of them too.
So, in these cases, NativeKey::GetFollowingCharMessage() should treat the key operation is already handled or canceled by the odd keyboard layout or somebody else. Additionally, in the latter case, following char message should be handled as orphan char message(s) as usual.

When NativeKey::GetFollowingCharMessage() tries to remove a char message from the queue, the message might be changed by odd keyboard layout or something. In such case, if the new char message is also caused by same physical key, the char message must be overwritten. Then, we should take the new char message instead.
Note that this patch saves original found char message into kFoundCharMsg and it's logged by each points for indicating if this case has occurred.

The machinery for suppressing the displayport during live resizes
was using the Observer service. However, in the case of multiple
browser windows, this meant that all the open browser windows would
have their displayport suppressed if *any* of the browser windows
was being resized. This was mostly ok, as the displayport suppression
would be turned off once the resize ended. However, the code to
kick off a repaint with the unsuppressed displayport would only get
triggered on one of the windows (whichever happened to process the
unsuppress message last).
This patch stops using the Observer service for the implementation
machinery, and instead locates the active TabParent of the relevant
nsWindow, and invokes the displayport suppression directly on that.
This fixes the repainting bug and also avoids unnecessarily
broadcasting the suppression/unsuppression notification to windows
that don't neccessarily need it.

When NativeKey crashes by itself, it means that we detect an impossible situation in usual environment. In such case, active 3rd party's keyboard layout or something other utility may hook API and returns odd result to us.
For investigating the cause and deciding what we should do in such cases, we should collect active keyboard layout name via crash reports.

This patch adds a new non-DOM event type, "mousetouchdrag". The name is horrible, I
know. The "mouse" comes from the fact that it's a WidgetMouseEvent, and the
"touchdrag" comes from the fact that this event is fired at the start of a touch
gesture for drag-and-drop. Right now this event is only fired from the Windows
widget code, when we receive a touch-source doubleclick event from the OS. This
event is sent to us from the OS when it detects the sequence "touchstart, touchend,
touchstart" within certain time/distance constraints. Eventually we may detect
similar gestures for other platforms in the APZ GestureEventListener and dispatch
the "mousetouchdrag" event for those as well.
The only effect of this event is that it begins tracking a drag gesture in the
EventStateManager. Subsequent touchmove events can begin the actual drag-and-drop
operation by calling ::DoDragDrop. See the discussion in bug 1147335 for some
important caveats about DoDragDrop and how it only works with left-mouse-button
events (real or synthetic).

I did my best to remove as much stuff as possible in this patch. The starting
point was to remove all the IsVistaOrLater() and IsWin7OrLater() calls, but I
also grepped for various strings and found some other removable stuff that way.
I may have still missed some things.
Notable things done by this patch.
- It removes numerous blocklist entries.
- It removes CanComputeVirtualKeyCodeFromScanCode(), because it's always true
now.
- It removes ShowXP{Folder,File}Picker(), even though these were available as
fallbacks on Vista+. The "when platform is built without the longhorn SDK"
condition in the comment above nsFilePicker::ShowXPFolderPicker() sounds like
it won't ever happen any more.
- It removes the config.trim_on_minimize preference. This requires adding a
bool sHaveInitializedPrefs variable; previously the lack of pref
initialization was indicated by the tri-state sTrimOnMinimize variable having
the value 2.
Notable things *not* done by this patch.
- ClearThemeRegion() still exists. The comment suggests that it is XP/Vista
only, but the code suggests otherwise. jimm thinks the comment is wrong.
- The comment in WinWakeLockListener::Callback() suggests that the StartTimer()
call is no longer needed to block the screen saver. I'm uncertain about this
and so I think it's best left to a follow-up.

When mWidget was already destroyed, anybody shouldn't dispatch WidgetEvent on it. Therefore, NativeKey::InitKeyEvent() has MOZ_CRASH() for detecting such dangerous bug and some users hit it.
Each message handler of NativeKey should check if mWidget has already gone.
Ideally, nsWindow shouldn't create NativeKey and try to handle the message with it. However, using NativeKey's message handlers can put some information to the log. Therefore, this patch doesn't touch nsWindow.

After click events with button 2 or 3 are fired, fire auxclick, a new
event intended to represent a non-primary mouse click. Because this
event, based on the design examples and blink's implementation, is
intended to be used with content listeners, always dispatch on content
listeners--not just those that force all events to be dispatched (i.e.
document/window). This diverges from the behavior of our click events
from non-primary buttons.
Eventually, we hope this will replace click events for non-primary
buttons. For now, leave those events for compatibility reasons.
Additionally, add handling of this new event, where necessary.

When the first time user clicks download panel popup to hide the drop marker popup, Windows fires WA_ACTIVATE with wParam includes WA_CLICKACTIVATE to the download panel.

When we jump to fullscreen, the OS sends a WM_MOUSELEAVE, which we turn into a eMouseExitFromWidget. The eMouseEnterIntoWidget was previously only sent when the mouse moved into the widget, which required the mouse to move. When entering fullscreen, we want the eMouseEnterIntoWidget to happen right away.
Currently, KeyboardLayout doesn't support chained dead keys because probably, the initial developer didn't expect there are such keyboard layout. Additionally, if we'd try to handle them with KeyboardLayout, it'd need to create too big and too complicated table at loading such keyboard layout. It's really nightmare. Therefore, this patch takes different approach.
Currently, when WM_(SYS)KEYDOWN is received, KeyboardLayout (and NativeKey) respects following WM_(SYS)CHAR. Similarly, this patch makes KeyboardLayout respect WM_(SYS)DEADCHAR when it handles dead key. If WM_(SYS)KEYDOWN is followed by WM_DEADCHAR, that means that the key press is in a dead key sequence and not finishing the existing dead key sequence. Therefore, when WM_(SYS)KEYDOWN is followed by WM_(SYS)DEADCHAR, KeyboardLayout activates dead key sequence.
For supporting dead key chain, this patch makes KeyboardLayout::mActiveDeadKey and KeyboardLayout::mDeadKeyShiftState arrays. When dead keydown message is received, KeyboardLayout appends an item to each of them. (I.e., when the array is not empty, it's in a dead key sequence.)
When WM_(SYS)KEYUP is received, KeyboardLayout checks if it's in mActiveDeadKey. If it's included in the array, it initializes NativeKey as a dead keyup event.
Otherwise, when non-printable key (probably) is received in a dead key sequence, KeyboardLayout doesn't handle it as a part of the dead key sequence. For example, a modifier key may be pressed for next key. (Even if the keyboard layout maps text input to a non-printable key, we can ignore them because such key's KeyboardEvent.key value should be decided only with the virtual keyboard.)

When using the InjectTouchInput API on Windows, the API requires that the caller
keep providing input frames (by calling the API function) at least every 100ms.
If the caller fails to do so, Windows can return an ERROR_TIMEOUT and throw
away the touch sequence. In some tests, it is hard for us to make this guarantee,
because we need to wait for other events between the touchdown and touchup. For
these tests, we can use the widget-level touch injection code that we have as
a fallback for the OS-level touch injection code. The widget-level touch
injection is less representative of real-world usage but allows us to bypass
the timeout problem.
