Currently, if an event is consumed in the main process, EventStateManager
does not send it to remote process. However, this is unexpected behavior
for some WidgetKeyboardEvent dispatchers. OS sometimes has consumed native
key events before sending applications. For example, Alt key on Windows
should activate menu bar of focused window but Alt key may be consumed before
focused window receives the event. In such case, we mark Alt keyboard event
as "consumed before dispatch", and chrome treat it like as its preventDefault()
is called in web content. (Note that for compatibility with other browsers,
the consumed state is not exposed to web content. So, Event.defaultPrevented
returns false in web content.)
Therefore, we need to treat "consumed" state and "cross process forwarding"
state separately. This patch makes calling WidgetEvent::PreventDefault()
always stops cross process forwarding for backward compatibility. Additionally,
for the special case mentioned above, this patch makes
WidgetEvent::PreventDefaultBeforeDispatch() take additional argument,
|aIfStopCrossProcessForwarding|. If this is CrossProcessForwarding::eStop,
the event won't be sent to remote process as same as calling PreventDefault().
Otherwise, CrossProcessForwarding::eHold, PreventDefaultBeforeDispatch() call
does not change "cross process forwarding" state. I.e., if the event's
StopCrossProcessForwarding() and PreventDefault() are not called until
EventStateManager::PostHandleEvent(), the event will be sent to remote process
as usual.

When AltGr key is pressed, following messages come:
1. WM_KEYDOWN for ControlLeft
2. WM_KEYDOWN for AltLeft
3. WM_SYSKEYUP for ControlLeft
4. WM_KEYUP for AltLeft
In these key sequence, KeyboardEvent.key value of keydown event at #2 and keyup
event at #4 should be "AltGraph". This patch fixes the key value and
adding new test into test_keycodes.xul to check the behavior with
SynthesizeNativeKey().

Users can emulate AltGr key with pressing both Ctrl key and Alt key on Windows
since AltGr is represented as so in Windows and physical keyboard may not have
AltRight key.
If user emulates AltGr key, we should set MODIFIER_ALTGRAPH to a set of
keyboard events for printable keys only when the key press produces
character(s) or a dead key. For example:
1. ControlLeft keydown event should make ctrlKey true.
2. AltLeft keydown event should make altKey true (not AltGraph state).
3. ctrlKey and altKey of printable keydown, keypress and keyup events should be
set to false, but getModifierState("AltGraph") should return true.
4. AltLeft keyup event should make altKey false.
5. ControlLeft keyup event should make ctrlKey false.
(If AltLeft key is pressed first, altKey of AltLeft keydown is true and
both altKey and ctrlKey of the following ControlLeft keydown are true as
usual.)

By the proposal from Google, <https://github.com/w3c/uievents/issues/147>,
Chromium treat AltRight key as "AltGraph" modifier if the keyboard layout
has AltGr key.
When AltRight key is pressed with a keyboard layout which has AltGr key,
modifiers should as following:
1. "keydown" for ControlLeft:
ctrlKey: true, altKey: false, getModifierState("AltGraph"): false
2. "keydown" for AltRight:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): true
3. Some "keydown", "keypress" and "keyup" events:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): true
4. "keyup" for ControlLeft:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): true
5. "keyup" for AltRight:
ctrlKey: false, altKey: false, getModifierState("AltGraph"): false
So, only when the preceding "keydown" event for ControlLeft, ctrlKey should
be set to true as usual. However, after AltRight key is pressed actually,
we should treat "AltGraph" modifier is true and both ctrlKey and altKey
should be set to false for web apps can handle text input normally.
So, MODIFIER_ALTGRAPH and MODIFIER_CONTROL/MODIFIER_ALT should not be set
at the same time.
This patch makes ModifierKeyState have only MODIFIER_ALTGRAPH or
MODIFIER_CONTROL/MODIFIER_ALT.
Additionally, this patch makes VirtualKey::ShiftState treat "AltGraph" as a
modifier. So, now, VirtualKey needs to convert ShiftState to index value when
it accesses its mShiftStates array. Therefore, this patch adds
VirtualKey::ToIndex() and make each VirtualKey method use it before
accessing mShiftStates.
Note that this patch also fixes bug of WinUtils::SetupKeyModifiersSequence().
The constructor of KeyPair takes 2 keycode values, but the second virtual
keycode can have scancode to distinguish if the key is left or right.
However, WinUtils::SetupKeyModifiersSequence() never sets scancode to
KeyPair. Therefore, it fails to dispatch AltRight key event.

We expose the relevant APIs on textarea and input elements anyway
(chromeonly). The QIs will throw on a non-input or non-textarea element, but
none of these consumers expect that to happen.
If a key combination causes text input, we need to dispatch keypress
events without alt/ctrl/meta modifiers since TextEditor won't handle
keyepress events whose altKey, ctrlKey or metaKey is true as inputting
text.
Currently, TextEventDispatcher sets mCharCode of eKeyPress event from
mKeyValue. Then, when altKey, ctrlKey or metaKey is true, it'll call
WillDispatchKeyboardEvent() and then, TextInputHandler needs to reset
the charCode value from native event information.
However, the problem is, TextInputHandler::InsertText() is called
with control character when control key is pressed and InsertText()
clears the modifier information before sending eKeyPress event to
TextEvenDispatcher so that TextEventDispatcher won't call
WillDispatchKeyboardEvent() even though control key is actually
pressed. Therefore, TextInputHandler cannot adjust charCode value
and modifier flags in some cases such as control + option + 'a'.
This patch makes InsertText() stop clearing the modifiers and
makes WillDispatchKeyboardEvent() do it instead. This procedure
is expected by TextEventDispatcher.

On macOS, option key is mapped to alt key, and it works like AltGr key on
the other platforms. Since our editor doesn't accept keypress events as
typing printable character if one of altKey, ctrlKey and metaKey of the
events is true, widget for macOS sets those attributes to false when an
editor has focus. On the other hand, if no editor has focus, our widget
does not do this hack so that altKey and ctrlKey values of keypress events
are always same as actual user operation and this is same behavior as the
other browsers. Therefore, we need to keep setting altKey of keypress
events to true if no editor has focus but we need to dispatch keypress
events even on content unless the charCode is 0.
So, only on macOS, WidgetKeyboardEvent::IsInputtingText() does not need
to check altKey state.

We'll start to dispatch keydown event and keyup event even during composition.
So, for testing those events won't break our UI, we should make
EventUtils.synhtesizeComposition() and EventUtils.synthesizeCompositionChange()
dispatch keydown event and keyup event even if callers don't specify keyboard
event explicitly.
Typically, "keydown" event is marked as "processed by IME", i.e., keyCode
value is set to DOM_VK_PROCESSKEY and key is set to "Process", with our
widget which handles native IME and key input. On the other hand, "keyup"
is NOT marked as so.
Therefore, this patch makes TextInputProcessor emulates this behavior without
any new special flags. And for making possible to emulate special cases,
this patch adds two flags to nsITextInputProcessor. One is
KEY_DONT_MARK_KEYDOWN_AS_PROCESSED. The other is KEY_MARK_KEYUP_AS_PROCESSED.
Unfortunately, those flags have opposite meaning but this must be better than
making necessary to one flag for emulating usual keydown/keyup events.
Finally, this makes some tests specify better keyboard information to
synthesizeComposition() and synthesizeCompositionChange() to emulate
actual keyboard events during composition.

On Windows, VK_PROCESSKEY key message is sent if the key event is handled by
IME (in IMM mode or IMM-IME). Therefore, we can set
WidgetKeyboardEvent::mKeyCode to NS_VK_PROCESSKEY and
WidgetKeyboardEvent::mKeyNameIndex to KEY_NAME_INDEX_Process simply when
we receive VK_PROCESSKEY.

I accidentally broke the ability to retrieve a big string from the
clipboard, and there was no test that failed. So this provides a new
test that does the following:
1. Store a big string in a nsTransferable.
2. Copy it to the clipboard.
3. Create a new nsTransferable, initialize with small data.
4. Populate the nsTransferable with (big) data from the clipboard.
5. Populate the nsTransferable with small data.
After each step, the test checks whether the transferable holds the
expected data and length, and (on non-Windows) checks that the big
data is backed by a file, and small data is not.

- Count open file descriptors instead of testing the existence of a file
(because the clipboard is now only reachable through file descriptors,
and not through a file path).
- Use a fixed string instead of a random string. The previous way of
generating a string was non-deterministic, and there was a very small
chance that the generated string was not large enough to trigger the
cache-to-disk-mode.
- Use "text/unicode" instead of "text/plain", because JavaScript strings
use two bytes, not one bytes each.
- The cache file is already created when the Transferable is created, so
check the cache file after assigning data to the nsITransferable, but
before copying it to the clipboard.

Gecko decides keyCode from an ASCII character which is produced by the key
by itself or with Shift on active keyboard layout or alternative ASCII capable
keyboard layout if active keyboard layout isn't ASCII capable. However, we've
ignored alternative ASCII capable keyboard layout's character if both the
key itself and with Shift don't produce ASCII alphabet nor ASCII numeral,
i.e., ASCII punctuation characters are not used in alternative ASCII capable
keyboard layout because of avoiding mapping a keyCode value to 2 or more keys.
However, setting 0 to keyCode value makes Firefox unusable with some web
applications which are aware of neither KeyboardEvent.key nor
KeyboardEvent.code. So, even if we map same keyCode value to a key, we should
avoid setting keyCode value to 0 as far as possible.
This patch's approach is, we behave same keyCode value as the alternative ASCII
capable keyCode is selected when computed keyCode value of active keyboard
layout is 0. This means that we will make some language users whose keyboard
layout for their language is not ASCII capable can use global web services
which support US keyboard layout of Firefox since the new keyCode values
are mostly computed with US layout on Windows or actual alternative ASCII
capable keyboard layout on macOS and Linux. In other words, we cannot improve
compatibility with web applications which don't support Firefox by this patch
since our keyCode values are really different from Chrome's. So, unfortunately,
if we'd use exactly same keyCode computation as Chromium, we'd break
compatibility with existing web applications which are aware of Firefox since
it's necessary to check UA name or something before using keyCode values.
Note that the most important difference between Windows and the others is,
such keyCode value is computed with alternative ASCII capable keyboard
layout on macOS and Linux but only on Windows, it's computed with OEM virtual
keycode. This means that only on Windows, the keyCode value may be different
from actual alternative ASCII capable keyboard layout's keyCode.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
