Bug 1343075 - 1a. Add TextEventDispatcherListener::GetIMEUpdatePreference; r=masayuki
Add a GetIMEUpdatePreference method to TextEventDispatcherListener to
optionally control which IME notifications are received by NotifyIME.
This patch also makes nsBaseWidget forward its GetIMEUpdatePreference
call to the widget's native TextEventDispatcherListener.
Bug 1343075 - 1b. Implement GetIMEUpdatePreference for all TextEventDispatcherListener; r=masayuki
This patch implements GetIMEUpdatePreference for all
TextEventDispatcherListener implementations, by moving previous
implementations of nsIWidget::GetIMEUpdatePreference.
Bug 1343075 - 2. Allow setting a PuppetWidget's native TextEventDispatcherListener; r=masayuki
In PuppetWidget, add getter and setter for the widget's native
TextEventDispatcherListener. This allows overriding of PuppetWidget's
default IME handling. For example, on Android, the PuppetWidget's native
TextEventDispatcherListener will communicate directly with Java IME code
in the main process.
Bug 1343075 - 3. Add AIDL interface for main process; r=rbarker
Add AIDL definition and implementation for an interface for the main
process that child processes can access.
Bug 1343075 - 4. Set Gecko thread JNIEnv for child process; r=snorp
Add a JNIEnv* parameter to XRE_SetAndroidChildFds, which is used to set
the Gecko thread JNIEnv for child processes. XRE_SetAndroidChildFds is
the only Android-specific entry point for child processes, so I think
it's the most logical place to initialize JNI.
Bug 1343075 - 5. Support multiple remote GeckoEditableChild; r=esawin
Support remote GeckoEditableChild instances that are created in the
content processes and connect to the parent process GeckoEditableParent
through binders.
Support having multiple GeckoEditableChild instances in GeckoEditable by
keeping track of which child is currently focused, and only allow
calls to/from the focused child by using access tokens.
Bug 1343075 - 6. Add method to get GeckoEditableParent instance; r=esawin
Add IProcessManager.getEditableParent, which a content process can call
to get the GeckoEditableParent instance that corresponds to a given
content process tab, from the main process.
Bug 1343075 - 7. Support GeckoEditableSupport in content processes; r=esawin
Support creating and running GeckoEditableSupport attached to a
PuppetWidget in content processes.
Because we don't know PuppetWidget's lifetime as well as nsWindow's,
when attached to PuppetWidget, we need to attach/detach our native
object on focus/blur, respectively.
Bug 1343075 - 8. Connect GeckoEditableSupport on PuppetWidget creation; r=esawin
Listen to the "tab-child-created" notification and attach our content
process GeckoEditableSupport to the new PuppetWidget.
Bug 1343075 - 9. Update auto-generated bindings; r=me
You know, when Korean IME commits string, then it sometimes set next preedit string. So reseting context causes that next preedit string is committed.
So we shouldn't reset IME context with preedit_end.

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.

TargetClauseOffset is the offset from start composition offset. So we should add start composition to calaculate correct rects.

Here is the patched build's log:
[Main Thread]: I/nsGtkIMModuleWidgets GTKIM: 7fab5a60a2c0 CreateTextRangeArray(aContext=7fab5a7bbbf0, aCompositionString="÷" (Length()=1))
[Main Thread]: W/nsGtkIMModuleWidgets GTKIM: 7fab5a60a2c0 SetTextRange(), FAILED, due to no attr, aTextRange= { mStartOffset=0, mEndOffset=1 }
[Main Thread]: W/nsGtkIMModuleWidgets GTKIM: 7fab5a60a2c0 SetTextRange(), FAILED, due to current clause length is 0
[Main Thread]: E/nsGtkIMModuleWidgets GTKIM: 7fab5a60a2c0 SetTextRange(), FAILED, due to g_utf8_to_utf16() failure (retrieving current clause)
[Main Thread]: W/nsGtkIMModuleWidgets GTKIM: 7fab5a60a2c0 CreateTextRangeArray(), inserting a dummy clause at the beginning of the composition string mStartOffset=0, mEndOffset=1, mRangeType=TextRangeType::eRawClause
iBus Chewing IME has two clauses when user presses Shift+p, one doesn't have pango_attr, the other is empty. These clauses are not useful in Gecko. Additionally, TextRangeArray assumes that there is a clause at beginning of the composition when there is one or more clauses. Therefore, this patch tries to insert dummy clause at the beggining of composition in such case.

I think that we can drop nsIMEUpdatePreference::DontNotifyChangesCausedByComposition(), i.e., nsIMEUpdatePreference::NOTIFY_CHANGES_CAUSED_BY_COMPOSITION because it's now used only by TSFTextStore but TSFTextStore ignores if SelectionChangeDataBase::mCausedByComposition or TextChangeDataBase::mCausedOnlyByComposition is true (for supporting async changes in e10s mode). So, only issue is, dropping the flag might cause increasing computing TextChangeData cost during composition in TSF mode. However, now, it's already enough fast and even if it'd cause performance regression, we could add a hack with TextComposition's offset information. Therefore, we don't need to worry about the performance regression so seriously.

Currently, all widgets request selection change notifications to IMEContentObserver. Additionally, IMEContentObserver needs to listen selection changes for caching latest selection for eQuerySelectedText. Therefore, it doesn't make sense to keep defining nsIMEUpdatePreference::NOTIFY_SELECTION_CHANGE.
If widgets didn't need selection change notifications, they could just ignore the unnecessary notifications.
Note that all widgets don't need selection change notifications if a plugin has focus and IMEContentObserver cannot observe selection changes in the plugin. Therefore, if IMEContentObserver is initialized with a plugin, it shouldn't listen selection changes (and doesn't need to notify widgets of selection changes).

Selection cache might be updated on commit string, so it should be updated correctly. Also, IMContextWrapper::OnSelectionChange() already has the check for composing using IsComposing().

For making our code clearer by the stronger type check, we should change the anonymous enum for NS_TEXTRANGE_* to enum class whose name is "TextRangeType" and whose type is "RawTextRangeType" which is an alias of uint8_t.
Additionally, this also adds some utility methods for them.
Note that some lines which are changed by this patch become over 80 characters but it will be fixed by the following patches.

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 bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
