TSFTextStore should discard pending composition update actions when it records
end composition update action because end composition update action causes
dispatching eCompositionCommit event and it replaces old composition string
anyway. So, following eCompositionChange which is dispatched by preceding
composition update actions are just redundant.

TSF doesn't send WM_KEYDOWN nor WM_KEYUP to us while it handles a key message
with ITfKeystrokeMgr::KeyDown() or ITfKeystrokeMgr::KeyUp(). Therefore,
TSFTextStore needs to store handling key event message during calling
those methods and if it does something, we need to dispatch eKeyDown event
or eKeyUp event before dispatching any events.
However, we shouldn't dispatch WidgetKeyboardEvent during a document lock
because TSF/TIP do not assume that document is broken during a document lock.
Therefore, TSFTextStore needs to put it as a pending action into the queue.
So, this patch wraps this with
TSFTextStore::MaybeDispatchKeyboardEventAsProcessedByIME(). It checks if
there is a document lock when it's called. If it's locked (and not yet
dispatched keyboard event for the handling key message), it adds pending
action to dispatch keyboard event later. Otherwise, (and not yet dispatched
one), it dispatches keyboard event directly.

The renaming problem is, when I try to convert 2nd or later clause of
composition string with Japanist 10, it shows candidate window below the
start of composition string first, then, it moves candidate window to
below the selected clause. This is caused by our bug of the hack in
TSFTextStore::GetTextExt().
First, we compute wrong minimum modified
offset of mContentForTSF. It stores last composition string when it's
initialized. Then, when a part of composition string is modified, it
sets minimum modified offset with the last composition string. However,
we don't update it when we receive notifications from content which means
all dispatched composition events are handled in content and
ContentCacheInParent stores character rects at least in this time. So,
this patch adds TSFTextStore::Content::OnCompositionEventsHandled() to
update the last composition string.
Next, TSFTextStore::GetTextExt() always adjusts acpStart to start of
composition string when acpStart is larger than composition start.
However, this causes this remaining problem. If ContentCacheInParent
stores character rects of even older composition string, we should use
it as far as possible. This must not be problem in most cases since
most Chinese characters and Japanese Kana characters have same width.
This touches share code of the hack between any TIPs. However, this must
not be risky because this patch just reduces amount of adjusting acpStart
offset in safe range.

If remote process hasn't handled dispatched commit event yet, TSFTextStore
needs to dispatch query content event relative to latest composition string
information. So, TSFTextStore::mContentForTSF should cache composition start
and composition string length until pending composition events are handled
by content actually.
MozReview-Commit-ID: ARM851nNZGz
When composition events are handled by content actually, widget receives
NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED notification. If focused content
is in a remote process, this is notified only when all sending composition
events are handled in the remote process. So, when widget receives the
notification can there is no composition in IME, that means that nobody is
composing composition at that time.
This patch adds TextEventDispatcher::IsHandlingComposition() which returns
false only when nobody has composition and makes TSFTextStore refer this
method because TSFTextStore needs to know if focused content has composition
in any cases.

This patch adds following Microsoft's IMEs into the black list which set
their open state to "closed" when input scope is set to IS_URL and sets
input scope for the URL bar to IS_DEFAULT.
Additionally, this adds a new pref to disable this hack because a lot of
users will affect this hack but perhaps, somebody may not like this if
they use tablet.
The new black listed IMEs:
- Microsoft Bopomofo
- Microsoft ChangJie
- Microsoft Phonetic
- Microsoft Quick
- Microsoft New ChangJie
- Microsoft New Phonetic
- Microsoft New Quick
- Microsoft Pinyin
- Microsoft Pinyin New Experience Input Style
- Microsoft Wubi
- Microsoft IME for Korean (except on Win7)
- Microsoft Old Hangul

The functions changed are given signed arguments (that are converted to unsigned).
Changing them to signed resolves the warnings and preserves the original values.

When "mozAwesomebar" is set to inputmode value, that means that the Smart
Location Bar gets focus. In that case, we should notify IME of input scopes
as "URL" because on-screen keyboard for URL has some useful additional keys
but they are not hindrances even when users want to type non-URL text.
On the other hand, MS-IME for Japanese and Google Japanese Input changes their
open state to "closed" if we notify them of URL input scope. A lot of users
complain about this behavior. Therefore, we should notify only them of
"Default" input scope even when "mozAwesomebar" has focus.

This is remaining cases of bug 1312302. TSF may set focus to context when it receives focus related message. In such case, TSF tries to retrieve selection but TSFTextStore::GetSelection() returns E_FAIL due to still not initialized, TSF crashes.
This patch moves the hack to TSFTextStore::GetSelection() and restrict to work only on problematic versions of Windows 10.

TSFTextStore::GetIMEOpenState() may be called a lot. Therefore, TSFTextStore should cache the compartment until shutting down.

sMessagePump is necessary only when WinUtils::(Get|Peek)Message() retrieves a message from the queue. Therefore, we can put off to initialize it until then.

Getting all prefs for TSFTextStore during initializing may make damage to start up performance.
So, each one should be retrieved when the one is actually necessary.
This patch creates TSFPrefs (I like better to name it TSFPreferences, but such long name isn't better when calling long name methods.) and implemented by simple macro.

ITfProcessorProfiles are used by a debug method TSFTextStore::CurrentKeyboardLayoutHasIME() and TSFStaticSink (when it's initialized). However, TSFStaticSink isn't necessary until when TSFTextStore needs to hack something for specific IME or notifying IMEHandler of active TIP change. So, we can put off to create the instance of ITfInputProcessorProfiles and TSFStaticSink.

TIPs (and normal keyboard layouts) don't need IMC on focused window. So, in most environment, it's not necessary to restore default IMC of focused window.
Therefore, this patch makes IMEHandler not restore default IMC unless legacy IMM-IME is active and disassociate IMC from focused window when IMM-IME isn't active.
However, this is risky change. Therefore, the new behavior is disabled in default settings. On the other hand, we need the new behavior only when MS-IME for Japanese is active on Win10. Therefore, this patch adds a pref to enable/disable the hack and make it true in the default settings.

While initializing or destroying TSFTextStore, each object methods should be
called after the instance is grabbed by local variable since member variable
may be cleared by nested call to destroy a TSFTextStore instance.

When PC supports table mode, TextInputFramme.dll is loaded and it can be used for TIP.
When creating new TextStore object, selection might be nothing yet on e10s. At this time, GetSelection will return E_FAIL since selection data isn't received yet. If GetSelection returns error during SetFocus, TextInputFrame.dll will crash.
So we set temporary selection to avoid crash.

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.
MozReview-Commit-ID: 2tPlcEA0MI0
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.
MozReview-Commit-ID: 9fj0GREbX18
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.
