This patch defines mozilla::SelectionType as an enum class. This is safer than nsISelectionController::SELECTION_* since setting illegal value to its variable is checked at build time. So, as far as possible, this should be used everywhere (but of course, this isn't available in scriptable interfaces).
And also this implements some useful methods for managing SelectionType and RawSelectionType which are implemented in layout/nsSelection.cpp because nsISelectionController is implemented by both PresShell and nsTextEditorState. Therefore, implementing one of them may make hard to find them. On the other hand, nsSelection.cpp is a better file name to look for them.
Note that this patch creates mozilla::Selection::RawType() for binding. Native code should keep using Selection::Type() but the binding code needs to use RawType() due to impossible to convert from SelectionType to RawSelectionType without explicit cast.

Add a pref "layout.accessiblecaret.always_show_when_scrolling" defaults
to true on all platforms except b2g. When it is set to false, the carets
will be hidden during scrolling, which is the current behavior before
applying this change.
The pref "layout.accessiblecaret.extendedvisibility" was added for
Fennec to keep ActionBar open when carets temporarily hiding during
panning or zooming. Now we make carets always show by default, so the
pref can be removed. However, the floating toolbar still need to be
notified when the scrolling begins, so we dispatch "scroll" instead.
In gtest, the preference changes were in the middle of the test
function. To make the preference change clearer, I add new pref changes
or move the existing ones to the beginning of the test functions.
The 250ms transition effect added in ua.css is per request of UX
designer in bug 1249201 comment 12.

FindFirstNodeWithFrame() and CompareRangeWithContentOffset() share a lot
of code duplication. I refactor and rename the two functions to improve
the readability.

This is to support Firefox Android L style carets assets that the two
carets always look like tilt.

After calling FlushLayout(), PresShell::Destroy() might be called and we
should consider PresShell and other resources will be no longer valid.
Before this patch, AccessibleCaretManager and AccessibleCaret(s) are
deallocated in PresShell::Destroy(). However FlushLayout() are all
invoked in AccessibleCaretManager, we need to keep manager alive to
clean up after PresShell::Destroy().
This patch makes AccessibleCaretManager live after PresShell::Destroy(),
and use IsTerminated() to check whether PreShell is vaild after each
FlushLayout() calls.
Note that event though AccessibleCaretEventHub will be unref in
PresShell::Destroy(), all the callers to AccessibleCaretEventHub's
public methods already add a ref to AccessibleCaretEventHub. So we don't
need to worry about AccessibleCaretEventHub and AccessibleCaretManager
die immediately after PresShell::Destroy().

Fennec enables sCaretsExtendedVisibility which uses
Appearance::NormalNotShown instead of Appearance::None to keep actionbar
shown during scrolling. This breaks selection mode update when the
positions of the carets are not changed after scrolling.
To fix this, we need to implement appearance recovering for selection
mode scrolling like we did for cursor mode in bug 1212732, and make
UpdateCaretsForSelectionMode() respects UpdateCaretsHint.

Per request in bug 1240917 comment 15, we decided not to show caret when
single press on an empty input. This effectively reverts the work in Bug
1230582.
The blur event will hide the carets and produces a standalone selection
highlight without carets. When a user long-pressing on the highlight, we
should show carets for the original selection highlight instead of
select a new word.
The helper UpdateCaretsWithHapticFeedback() should only be needed when
long-pressing. It should suffice to live within SelectWordOrShortcut()
instead of being a member function.
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.

Currently, the caret in cursor mode is always hide after scrolling. I
think it's better to restore its appearance if it's logically visible
before scrolling. That is:
1) If the caret is logically visible (Normal or NormalNotShown) before
scrolling, update carets on scroll-end to show the caret again.
2) If the caret is hide due to timeout or blur, it should remain hidden
on scroll-end.
TouchCaret does not have this issue since it clamps the dragging point
to the editable content boundary.
Fix this bug by porting TouchCaret::GetContentBoundary() to
AccessibleCaret. I apply the clamp logic to both cursor mode and
selection mode if the focus node is on an editable content, which makes
carets dragging in selection mode smoother than SelectionCarets.
After HideCaret() is called via keyboard event,
OnScrollPositionChanged() still fire another CaretStateChanged event
even if the caret is hidden. We follow OnReflow() to update carets only
when carets are logically visible.
A test case:
1. Type a string on the rocketbar until the text is long enough to scroll.
2. Copy arbitrary string.
3. Tap on rocketbar to show caret, and move it to the end (within 15
seconds timeout)
4. Type a character.
The text selection dialog should not show.
We should dispatch CaretStateChanged event in OnReflow() in cursor mode
when the first caret's appearance is NormalNotShown. Otherwise the text
selection dialog won't update its position.
We need to extract statements that touch PresShell, access frame trees,
or call other utility functions into functions so that we could mock or
stub them in gtest.
Inline GetFocusedContent since it's only used once.
Rename mCaretMode to mLastUpdateCaretsMode to make it clear that this
variable track the caret mode since last update. This also avoid the
confusion that GetCaretMode() returns mCaretMode.
The old SelectionStateChangedEvent dispatched by SelectionChanged had
this field, but it has not being ported to CaretStateChangedEvent. We
should include selected text in the event so that Gaia could have a
chance to enhance user experience.
This functions is for hiding caret in cursor mode on desktop browser
when receiving NS_WHEEL_WHEEL, which is never used on B2G in production.
On desktop browser, a proper wheel scroll cycle begins by NS_WHEEL_START
and ends by NS_WHEEL_STOP, which was covered by gtest. Move the three
marionette test for TouchCaret only.
