If WM_GETOBJECT for OBJID_CARET is received but a11y module is not active,
IME module should create native caret over our caret because Windows will
handle the request with native caret automatically and we don't need to
enable a11y module only for it.
This patch makes IMEHandler store whether such message has been received and
makes TSFTextStore create native caret when composition, selection or layout
is changed because especially when there is composition, only TSFTextStore
knows correct position to put caret if there is composition or some dispatched
events have not been handled by content process yet.
Note that IMMHandler already does that since some legacy IMEs require native
caret to show its UI and we cannot check active IME strictly. Therefore, this
patch does not touch IMMHandler.

IMEHandler needs to create native caret later (when there is no composition).
Therefore, IMEHandler should manage whether it creates native caret or not
and IMMHandler and TSFTextStore should create/destroy native caret via
IMEHandler.
Note that this patch makes IMMHandler stops managing whether native caret
is created for plugin or not because native caret is created only one instance
and anyway IME handlers should stop managing native caret when they loses
focus.

If a11y module is active, it observers caret position and size, and when caret
position or size is changed, it creates/moves native caret to overlap with
our caret.
On the other hand, IME module also creates native caret if active IME requires
it. Therefore, both of them conflicts each other.
This patch makes IME module stop touching native caret if a11y module is active.
Although, a11y module with Flush Player does not work well for IME. Therefore,
this patch keeps the conflict between them as-is for now.

If TSFTextStore fails to get selection, e.g., the content is really odd like
fuzzing tests, its mSelectionForTSF is marked as dirty. However, Windows may
try to retrieve writing mode while we're creating new TSFTextStore. Then, we
may hit MOZ_ASSERT(!mDirty) in TSFTextStore::Selection::GetWritingMode() in
debug build.
So, we need to make some callers of GetWritingMode() check whether selection
is marked as dirty.

ATOK 2016 and newer may show candidate window at odd position temporarily
when user converts a word quickly (e.g., keep pressing space bar).
For avoiding this flicker, we should keep hacking GetTextExt() result for
ATOK 2016 and later even after Windows fixes TS_E_NOLAYOUT bug.
We should get feedback from each CJKT testers at least one cycle after Win10
RS5 is released. Until then, we should not stop hacking GetTextExt() result
in late Beta nor Release builds.
Microsoft Pinyin and Microsoft Wubi (Simplified Chinese TIPs) work better on
Windows 10 Build 17643 or later (i.e., TS_E_NOLAYOUT bug is fixed). However,
they sometimes do not show candidate window, perhaps, the reason is something
stateful bug in them. Therefore, we still need to hack the result of
GetTextExt() until they fix this bug.
Currently, TSFTextStore::MaybeHackNoErrorLayoutBugs() checks pref to enable
hack first, then, check if active TIP is the target of pref. This was intended
to save comparison cost of GUIDs. However, we don't need to worry about the
cost and that was not makes sense since all prefs are true by default.
So, this patch makes the big if-elseif blocks with switch-case with
TSFStaticSink::ActiveTIP(). Then, each case block starts to check if
- if Windows still TS_E_NOLAYOUT bug of GetTextExt().
- if corresponding pref is true.
Note that this duplicates some code for making the code look easier.
E.g., eMicrosoftOfficeIME2010ForJapanese case is duplicated from
the eMicrosoftIMEForJapanese case. eMicrosoftPinyin and eMicrosoftWubi case
is duplicated from the eMicrosoftChangJie and eMicrosoftQuick case.
As we know, GUID comparison is not cheap if it's required a lot. Unfortunately,
we need to check it more in TSFTextStore::MaybeHackNoErrorLayoutBugs() and
it's called a lot. So, even though mapping from GUID to TIP is expensive,
we should do it only once. Note that most users won't change IME during a
browser session, so, running this expensive method once must be reasonable.
On the other hand, we don't allow to make damage to start up performance,
we should avoid to do it as far as possible. For example, when we need to
check if active TIP is a specific TIP, we should check current language.
At Windows 10 build 17643, Microsoft fixed the bug of TSF which returns E_FAIL
to TIP when GetTextExt() returns TS_E_NOLAYOUT. With this fix, most TIPs do
not have any problems even if we return TS_E_NOLAYOUT. So, unless active
TIP still needs the hack, the method can skip the hack if running on build
17643 or later.
Note that we still need to support Japanist 10 and Microsoft Office IME 2010.
It confirmed that Japanist 10 has a bug of handling TS_E_NOLAYOUT. On the
other hand, we have not tested Microsoft Office IME 2010 since it's installable
only into Win7 or Win8 and needs to upgrade it to Win10 for testing, but I
do not have the license. After the fix comes into release channel, I'll be
able to test it though (my main environment is Win10 and it was installed
before upgraded). So, we need to be back after Microsoft releases the fix.

The block in TSFTextStore::GetTextExt() which decides whether we should return
S_OK with unmodified character rectangle rather than TS_E_NOLAYOUT is too big.
Additionally, we need to add new condition to check Windows 10's version there.
That makes the large block more complicated. So, we should split the block
off from TSFTextStore::GetTextExt(). Then, we can use early-return-style to
reduce the deep indentations.

When user removes all composition string of MS Pinyin, MS Wubi, MS ChangJie and
MS Quick with Backspace key, IME commits last character temporarily and
restart composition to replace the last character with empty string when
user tries to remove last one character.
This causes flicking composition string because the additional composition
selects the character and it may be painted immediately before removed, and
also editor will have unnecessary undo transaction.
Therefore, as same as bug 1208043, TSFTextStore::RecordCompositionStartAction()
should restart last composition in such case. Fortunately, we implemented
similar code for bug 1208043, however, unfortunately, we don't have preceding
pending compositionstart in this case. Therefore, this patch makes
pending compositionend store start offset of composition. Then, we can
restart composition only with information stored by pending compositionend
action. Additionally, this patch renames the method checking pending
actions for self-describing the new meaning.

We always struggle with a lot of IME bugs on Windows. Currently, any IME
vendors should've already released TIP for TSF rather than legacy IMM-IME
since IMM-IME is not available on UWP apps. Additionally, due to API
limitation, it's difficult to get human-friendly name of IMM-IME. So, let's
collect only TIP names of TSF on Windows. This must be enough.
Note that we cannot get common-English name even though the API to retrieve
TIP name taking language code. Therefore, a TIP may be collected with
different name, e.g., one is Japanese name and the other is English name.
If we collect GUIDs of TIP, we can avoid this issue. However, it's
difficult to collect both GUID and human-friendly name since Telemetry
key is up to 72 characters.
Currently, I give up to avoid this duplicated issue. Perhaps, this is not
so serious issue since most TIP users must match language of TIP and their
system language settings. Therefore, this patch collects Locale ID of
TIP and description of it. Locale ID is necessary because some TIPs may be
named same name for different languages. For example, both Japanese and
Hangul IMEs of Microsoft are named as "Microsoft IME".

Currently, TSFTextStore::GetTextExt() won't return TS_E_NOLAYOUT error when
ATOK retrieves text rect of all of the composition string.
However, if user converts 2nd or later clause, ATOK retrieves text rect after
start of the character of selected clause. Returning TS_E_NOLAYOUT in this
case causes candidate window being positioned temporarily below first character
of the composition string.
For avoiding the flicker of the candidate window, TSFTextStore::GetTextExt()
shouldn't return TS_E_NOLAYOUT when ATOK retrieves text rects *in* the
composition string.

Old ATOK referred native caret position to decide its candidate window position.
However, at least ATOK 2016 does not need to refer it. Additionally, if we
create native caret for ATOK 2016, the candidate window position, ATOK 2016
refers the native caret only when we cannot return expected rect. Therefore,
only immediately after modifying composition string, the position is different
from actual position by a couple of pixels and that looks like flicks the
candidate window.
So, we should stop creating native caret for ATOK 2016 (as same as ATOK 2017).

TSFTextStore should discard pending composition update actions when it records
end composition update action because end composition update action causes

OnUpdateComposition() may be called without new range instance by some TIPs
when they starts to modify composition string. At this timing, TSFTextStore
should append a pending action for dispatching keyboard event into the queue.
Without this patch, OnUpdateComposition() creates incomplete pending action
for composition update and then, MaybeDispatchKeyboardEventAsProcessedByIME()
appends pending action for dispatching keyboard event from another point
immediately (e.g., from SetText()), then, finally, the caller of
MaybeDispatchKeyboardEventAsProcessedByIME() appends another pending action
for composition update with proper composition string. Therefore, the
first pending action for composition update clears composition string before
actually updating it with new composition string. In other words, new
pending action for dispatching keyboard event splits a pending composition
update. So, this patch prevents the splitting.

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.

Although we haven't any bug reports caused by this, this is a really old bug.
When we implement TSFTextStore, we decided to use queue of dispatching
events and flush it when document lock is unlocked. When we implement the
queue, we got this regression.
When TSFTextStore::SetText() is called with different range from current
selection range, TSFTextStore::SetSelectionInternal() add
PendingAction::SET_SELECTION into the queue first for replacing existing
text or inserting text into different position if there is no composition.
Then, TSFTextStore::InsertTextAtSelectionInternal() inserts text at the new
selection range.
When TSFTextStore::FlushPendingActions() is called after that, eSetSelection
should be dispatched and then, new text is inserted wit a set of composition
events. However, we forgot to dispatch creating eSetSelection event.
So, this patch just dispatches the event.

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.

Currently, TSFTextStore::GetIMENotificationRequests() tries to return notification requests for focused text store. However, if there is sEnabledTextStore, all notifications will be sent for it. Therefore, TSFTextStore::GetIMENotificationRequests() should return notifications for sEnabledTextStore without checking focused text store in the thread manager.
For example, we try to keep active composition even if we're being inactivated because Windows steals focus from us when our main process becomes busy but user may want to continue to compose the composition after our process becomes available.
Additionally, if TSFTextStore::GetIMENotificationRequests() doesn't return IMENotificationRequests::NOTIFY_DURING_DEACTIVE, sEnabledTextStore will be broken by NOTIFY_IME_OF_BLUR which will be sent by IMEStateManager::OnChangeFocusInternal(). However, when we're being activated, NOTIFY_IME_OF_FOCUS won't be notified because focused remote process keeps having IMEContentObserver. Therefore, sEnabledTextStore won't be recreated and IME becomes unavailable.
