"ime-enabled-state-changed" notification was implemented for Android in bug 603848 but nobody currently observes this notification. Therefore, we can stop notify the observer service of this.

IMEContentObserver may have cache of normal selection. If it's available, IMEContentObserver should use it for computing absolute offset of WidgetQueryContentEvent whose mInput::mOffset is relative offset to selection.
This patch just improves the performance of such query.

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 should update its composition start offset after every DOM event dispatch with first clause's selection type if there is composition string.

Selection's focus and anchor node and offset are stored only for the last range. However, ContentEventHandler needs its first range. Therefore, ContentEventHandler shouldn't refer them if there are two or more selection ranges.

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.

TextComposition queries selection start offset a lot of times. Therefore, for reducing the runtime cost, it should use IMEContentObserver if it's available or ContentEventHandler, otherwise.

When composition string hasn't been non-empty, insertion point of the composition string can be changed by a DOM event handler. E.g., compositionstart, first compositionupdate and first text. Therefore, TextComposition should update the composition start offset cache after every event dispatch.

It's enough to store target clause offset from start of the composition and better to modify mCompositionStartOffset because when even if mCompositionStartOffset is changed, we don't need to modify the target clause offset.
This patch renames mCompositionTargetOffset to mTargetClauseOffsetInComposition.

In all of the places touched by this patch, the smart pointer we're
appending is about to become unused, so simply .forget()'ing its
reference into the appropriate nsCOMArray works just fine.
Currently, when TextComposition tries to forcibly commit composition synchronously, it cancels the composition if there is only an ideographic space since legacy Chinese IMEs for Windows were used an ideographic space as a placeholder and shows actual composition string in its owning window (called reading window).
However, Japanese TIPs basically use composition to input an ideographic space. Unfortunately, this intentional input of an ideographic space is always canceled if an editor commits to composition at every input event in TSF mode because TSF cannot commit during a call of ITextStore::RequestLock(). Additionally, we will enable e10s mode, then, on all platforms, requesting commit composition is handled asynchronously.
Therefore, we should make the hack disabled in default settings now. If we'll find a way to distinguish if an ideographic space is a placeholder, we should recover this hack. Note that such input fields cannot handle such legacy IMEs, so, disabling the hack in default settings must be fine.

For sending NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED after the other change notifications which was caused by the user input, we need to use IMEContentObserver::IMENotificationSender because it sends the notifications when it's safe to do it.
This patch makes TextComposition use IMEContentObserver to send the notification. However, if there is no active IMEContentObserver, e.g., composition events are fired on unfocused window, TextComposition sends it by itself (same as current implementation).
If IMEContentObserver stops observing when it has pending NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED, it cannot send the notification (i.e., it is discarded completely in such case). However, in such case, IMEContentObserver sends NOTIFY_IME_OF_BLUR. So, anyway, native IME handler should treat the blur notification as it including NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED.
On the other hand, we're buggy if composition events are fired in non-active window. Even in such case, IMEContentObserver should be created for active editor in each document and it notifies IME of the changes. But this is out of the scope of this bug.

It's not clear to me what NOTIFY_IME_OF_COMPOSITION_UPDATE means only from the name. For making the name clearer, this patch renames it to NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED and add some explanation to the definition.

The Rebind() call in HandleEvent was attempting to be clever by sharing
string data with the error event's message. Unfortunately, we
eventually needed to pass the message out to JS, which required copying
the string for JS's purposes. Fortunately, we can attempt to be even
more clever by noticing whether the error event's message is already
allocated as a string buffer and sharing that, rather than just the raw
data. In the best case, the string buffer can be shared out to JS and
we avoid some needless copying.
PuppetWidget::GetInputContext() needs to communicate with its parent process with synchronous IPC. This is very expensive for focus move.
Currently, IMEStateManager uses nsIWidget::GetInputContext() only for checking the IME enabled state. Therefore, it's enough to cache input context when nsIWidget::SetInputContext() is called. Then, we can avoid to communicate with synchronous IPC with PuppetWidget::GetInputContext() in most cases.
This patch makes IMEStateManager stores the last widget which sets input context. When PuppetWidget uses its input context cache, it should check if it is the last widget to set input context with IMEStateManager since an input context may be shared with other widgets and another one may have update the input context. I.e., PuppetWidget's input context cache may be already outdated after IMEStateManager sets input context with another widget.
This patch gives up to support retrieving IME open state from child process. However, perhaps, this is not necessary for everybody including add-on developers because the only user of IME open state in child process is nsIDOMWindowUtils. So, add-ons can send IME open state from chrome process instead. If this decision is wrong, unfortunately, we should support it again in another bug. It's easy to support with creating another nsIWidget::GetInputContext() or adding additional argument to it.

The web platform tests changes are just a cherrypick of
https://github.com/w3c/web-platform-tests/pull/2926 so I don't have to add
failure annotations until the next test uplift.
I've audited our uses of nsIFormControl, and this patch looks to me like it
preserves existing behavior in all but the following cases:
1) nsXBLPrototypeHandler::DispatchXBLCommand, the case of scrolling when space
is pressed while something inside a <label> is focused. We used to not scroll
in this situation; I think this is a bug, so I'm changing that behavior to
scroll instead.
2) In Accessible::RelationByType for the RelationType::DEFAULT_BUTTON case,
when mContent is a <label> we used to return its form's default submit element.
Now we will just return Relation().
KEYCODE_HOME was temporarily named as "MozHomeScreen" and KEYCODE_FOCUS was temprarily named as "MozCameraFocusAdjust" since they were not defined by the spec. However, in the latest spec, they are defined as "GoHome" and "CameraFocus". So, it is the time to rename them.
However, these temporary key names are still used by Gaia. Until it's fixed, we should keep using the temporary names only on B2G.

Android's KEYCODE_CALL was temporarily named as "MozPhoneCall" since proper key name was not defined in the spec. However, now, it's defined as "Call" in the latest spec. Therefore, we should rename this key name.
Note that this isn't available on Android because the key event is never fired on applications. However, this key may be useful on B2G. Although, the key is not used by current Gaia.

Note that this patch changes tests but they are not used by B2G. Therefore, just replacing with new name is enough.
Only forms.js is necessary #ifdef because the main purpose of forms.js is for B2G's IME framework. However, it's available on the other platforms if chrome needs to use it.
