Returing TS_E_NOLAYOUT while ATOK shows suggest window causes moving suggest window to odd position. This causes flicking the window. Therefore, we shouldn't return TS_E_NOLAYOUT in this case. In this case, ATOK queries whole rect of composition string. So, we can return TS_E_NOLAYOUT for other cases.

ATOK 2011 - 2016 check focused window class name if it's a Mozilla's window. Then, they refer native caret position for deciding its popup window. However, future ATOK release will stop referring native caret position on Mozilla's windows. Therefore, we can stop creating native caret for new ATOK.

Currently, TSFTextStore::GetTextExt() checks the offset with mContentForTSF.MinOffsetOfLayoutChanged() as "the first offset of modified characters", however, TSFTextStore::Content::IsLayoutChangedAfter() needs actual offset - 1. This is really not useful. So, we should rename it to IsLayoutChangedAt() and check the offset simply.
Additonally, TSFTextStore::GetTextExt() should set previous offset of MinOffsetOfLayoutChanged() when it hacks the queried range for avoiding bug of active TIP since setting offsets to the result of MinOffsetOfLayoutChanged() means the offset's layout is always not computed yet.

In CreateAndSetFocus(), SetInputScope() is called *after* setting focus to the context. At this time, Google Japanese Input retrieves InputScopes. Therefore, TSFTextStore returns IS_DEFAULT. But after that, Google Japanese Input tries to retrieve InputScopes after every notification (in this case, a call of ITextStoreACPSink::OnLayoutChange()). Then, we return IS_URL due to set after returns IS_DEFAULT.
This is actually our fault, but according to the other TIPs, Google Japanese Input shouldn't commit composition at detecting an InputScope change, though.

I'm still not sure what we should do in this case, though.
If mContentForTSF is initialized and there are some unknown changes in actual contents, i.e., not caused by composition of the active TIP itself, we cannot set selection range properly in some cases.
For example, if TSF tires to set non-empty selection range but the range has been removed by web apps.
For now, let's try to return E_FAIL in such case because that should occur at reconversion or something immediately after previous content change not caused by previous composition. If TIP does nothing in this case, user can retry with same operation after all pending text changes are notified to TSF.

Same as selection change notification, text change notification shouldn't be notified to TSF while there is cachec content because neither TSF nor TIP may allow to change text by web applications during keeping storing cached content.
This patch makes TSFTextStore stores and merges text changes until MaybeFlushPendingNotifications() is called and there is no cached content.

TSFTextStore shouldn't notify TSF of selection change until MaybeFlushPendingNotifications() is called and there is no cached content because while there is cached content, neither TSF nor TIP may allow to change selection by web applications. Therefore, ITextStoreACP::GetSelection() and similar methods need to use mSelection instead of actual selection in the focused editor. Therefore, TSFTextStore should store selection change data during keeping storing content cache and notify it when the cache is cleared. So, when TSFTextStore notifies TSF of selection change, TSFTextStore needs to update mSelection to the actual selection which is stored in mPendingSelectionChangeData.

This patch stop clearing mContentForTSF at unlocking the document because we should keep it until active composition is committed. If so, TSF/TIP won't be confused by content changes by JS. So, this is important for a11y of TIP users in some complicated websites like GoogleDocs, Facebook, etc.
Note that this patch doesn't work well without following patches. We need to stop notifying TSF of selection changes and text changed while mContentForTSF is valid.

While a TSFTextStore instance is being destroyed, TSFTextStore::Destroy() tries to commit remaining composition and notify TSF of destroying the view. At this moment, TSF/TIP may try to commit the composition or retrieve the contents with calling ITextStoreACP::RequestLock() but currently TSFTextStore disallows the requests to lock of them. This means that TSFTextStore never sends composition commit events asynchronously. Therefore, TextComposition may keep waiting remaining composition events but this causes odd behavior because they won't be fired.
For avoiding this issue, TSFTextStore should behave as normal even while it's being destroyed. Fortunately, if there is a composition, it always has mLockedContent and mSelection. So, it can compute expected results of TSF/TIP with them.

While TIP is handling a key message, TSFTextStore shouldn't release any TSF objects since it may cause hitting a bug of TIPs. Actually, MS-IME for Japanese on Windows 10 crashes when TSFTextStore is destroyed during composition because probably it accesses some destroyed objects to request to commit composition or query contents.

TSFTextStore::sEnabledTextStore is a static variable to grab a reference to focused TextStore instance. So, this may be changed by accidentally during a call of instance methods of TSFTextStore. Then, focused TextStore may be destroyed during running a method and crash when it accesses a member variable.
For avoiding this crash, static methods which call a method of sEnabledTextStore should create an independent RefPtr to it before calling the method.

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.
