It's difficult to create new test which checks "input" events caused by
all edit operations especially when text is inserted from our UI. Therefore,
this adds "input" event type checks into existing tests.
Additionally, this adds new test for MozEditableElement.setUserInput() whose
behavior needs to be fixed in this bug.
Currently, InputEvent interface should be used only on text controls or
contenteditable editor when dispatching "input" event.
https://w3c.github.io/input-events/#events-inputevents
You may feel odd to use different event interface for same "input" events.
However, other browsers also use InputEvent interface only in the cases. So,
we should follow them for now.

TextEditor modifies composition string or selected string when first
eCompositionChange event is received. However, TextComposition dispatches
eCompositionChange event ("text" event of DOM) only when composition string
becomes non-empty if current composition string is empty. So, when IME
dispatches only eCompositionStart and eCompositionCommit events for removing
selected text, TextEditor does nothing. This hacky behavior is used by
MS Pinyin on Windows 10 at least.
For supporting this behavior, we need to make TextComposition dispatch
eCompositionChange event when eCompositionChange(AsIs) event is fired
even before dispatching eCompositionChange event.
Although from point of view of web apps, the hacky composition should be
merged into the previous composition if it's possible but it's out of scope
of this bug.

We expose the relevant APIs on textarea and input elements anyway
(chromeonly). The QIs will throw on a non-input or non-textarea element, but
none of these consumers expect that to happen.
We'll start to dispatch keydown event and keyup event even during composition.
So, for testing those events won't break our UI, we should make
EventUtils.synhtesizeComposition() and EventUtils.synthesizeCompositionChange()
dispatch keydown event and keyup event even if callers don't specify keyboard
event explicitly.
Typically, "keydown" event is marked as "processed by IME", i.e., keyCode
value is set to DOM_VK_PROCESSKEY and key is set to "Process", with our
widget which handles native IME and key input. On the other hand, "keyup"
is NOT marked as so.
Therefore, this patch makes TextInputProcessor emulates this behavior without
any new special flags. And for making possible to emulate special cases,
this patch adds two flags to nsITextInputProcessor. One is
KEY_DONT_MARK_KEYDOWN_AS_PROCESSED. The other is KEY_MARK_KEYUP_AS_PROCESSED.
Unfortunately, those flags have opposite meaning but this must be better than
making necessary to one flag for emulating usual keydown/keyup events.
Finally, this makes some tests specify better keyboard information to
synthesizeComposition() and synthesizeCompositionChange() to emulate
actual keyboard events during composition.

Note that this patch also replaces legacy VK_* with KEY_*, and replaces
synthesizeKey() for inputting some characters with sendString() because
it's better and clearer what it does and it sets shiftKey state properly.

Now, callers of EventUtils.synthesizeKey() don't need to specify
KeyboardEvent.code value anymore if they assume that active keyboard layout
is US keyboard layout.
Note that this patch changes the meaning of only test_bug551434.html.
Some callers in it don't match the key value and code value but that looks
like that they don't checking such odd keyboard events. So, they must be
bug of the test.

`nsRange` registers mutation observers to adjust the range when content
changes. However, there are some cases where we adjust the start and/or
end offsets but don't notify selection listeners (i.e. we don't call
`nsRange::DoSetRange` to set the new range points, contrary to what the
comment above `nsRange::DoSetRange` says). This patch makes us call
`nsRange::DoSetRange` in those cases. The patch adds a testcase in
test_selectevents.html, and changes a few unexpected-pass cases in
test_composition_text_querycontent.xul that this patch fixed.

When the start node is a non-container node (i.e. <br>), and the start
offset is 0, we should not include a newline character for the node. For
example, for this range,
> <br/>hello
> \___/
the start node/offset is (<br/>, 0) and end node/offset is ("hello", 1).
The calculated range offset should be 0, and the range length should be
2: 1 for the <br/> newline character plus 1 for "h".
The patch also ensures this behavior for pre-mode nsContentIterator, for
both start and end node adjustments. For start nodes, we include any
non-container nodes with offset 0 in the range. For end node, we exclude
any non-container nodes with offset 0 from the range.

Between nsIDocumentObserver::BeginUpdate() and nsIDocumentObserver::EndUpdate(), IMEContentObserver can cache added nodes as a range if they are consecutive nodes. Even if a node is removed, a data node is changed or attribute is changed unexpectedly, IMEContentObserver can post text change of the added node range and handle it normally.

IMEContentObserver notifies IME of 3 notifications at most when editor is changed.
The order is:
1. text change (with merged range if 2 or more change occurred during an edit transaction)
2. selection change (only the latest selection change. other changes occurred before that during an editor transaction are ignored)
3. position change (scrolled, resized, window moved, etc)
This does not check the behavior in designMode because some operation in testWithHTMLEditor() causes unexpected behavior, e.g., moving focus. It *might* be bug of design mode. However, it doesn't matter for this bug. The important thing of this bug is, there should be automated tests for IMEContentObserver. And fortunately, IMEContentObserver does not check the type of editor. So, it's enough to test only contenteditable element for HTMLEditor at least for now. Therefore, I gave up to test it in designMode for now.

According to ATOK's behavior, IME may send different line breaker from its platform's standard. Therefore, we should treat \r as \n too.
Additionally, currently, TextComposition doesn't allow to input \n with composition. However, this was added for preventing to see odd control characters as boxes with code point. Therefore, we should allow \n for IMEs. (It was allowed, this limitation is unexpected when I reviewed the patch to reject control characters in TextComposition.)

Bug 1319660 - 1. Don't take shortcut if old replacement ranges don't match; r=esawin
The block at [1] is a shortcut we take when we reconcile Java text
changes with Gecko text changes. However, we only checked that the new
ranges are the same, i.e. that the new Gecko text is the same as the new
Java text. We should also be checking that the old ranges are the same,
i.e. that the replaced Gecko text is the same as the replaced Java text.

Bug 1319660 - 2. Use previous node instead of sibling when adjusting last node; r=masayuki r=smaug
nsContentIterator in pre mode adjusts its last node if the node is a
childless node like <br>. However, right now it's using GetPrevSibling,
which can lead to error in some edge cases such as:
<p></p><div><br></div>
In this case, if the last node is <br> with offset 0, GetPrevSibling
will return <p> because <p> is <br>'s parent's previous sibling, and the
last node will be set to <p>. However, the correct last node in this
case is <div>, because <br> with offset 0 refers to the position to the
left of <br>, which is <div> with offset 0. In this case, PrevNode
returns the correct <div> value, so we should set the last node to the
result of PrevNode.
For the first node, for a childless node in pre mode, GetNextSibling and
NextNode are the same, so there is no bug in this case. Nevertheless,
this patch changes the call to NextNode to be consistent with calling
PrevNode for the last node.
Bug 1319660 - 3. Add test for correctly adjusting last node in content iterator; r=masayuki
Add a test for the previous patch that makes sure querying selected text
in an edge case works correctly.
Bug 1319660 - 4. Add test for start node regression; r=me
Add a new test case for the NextNode() regression. r=me for trivial
test-only patch.
Bug 1319660 - 5. Restore GetNextSibling call for first node of pre-content-iterator; r=smaug
The last patch changed the `GetNextSibling()` call to `NextNode()`
because I assumed they're equivalent in this case. That turned out to
not be the case because we can reach this line even if the node has
children -- the index just has to be after the last child. So this patch
restores the `GetNextSibling` call to restore the correct behavior.
I also added some comment to clarify that we can reach this line due to
one of two conditions: 1) the node has no children; 2) the node has
children but the index is after the last child.
This patch also replaces the `HasChildren()` check when setting
`cChild`. If the index is after the last child (i.e. index ==
childCount), `GetChildAt()` fails and we erroneously log an assertion
warning, even though the input was valid. The new check handles all
cases whether start node has children or not.
Doing QI from nsIEditor to nsIEditorIMESupport doesn't make sense because editor should always support all methods and attributes of nsIEditorIMESupport (it does NOT mean that all nsIEditor implementation need to support IME).
This patch moves all of them to nsIEditor for avoiding redundant QIs.

eQueryTextRect is used by widget and eQueryTextRectArray is used by ContentCacheInChild. So, matching their result guarantees that widget can get same result both in non-e10s mode and e10s mode. So, the matching should be tested.

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).
