We want HasNonEmptyTextContent() to descend recursively into editingHost
since <div contenteditable="true"><span>123</span></div> should be
considered as non-empty.
This patch check whether nsCaret shows in scroll frame. If yes, touch
caret will show, and its position will be clamp to scroll frame as
before. Otherwise, we hide it since the nsCaret will not be seen in this
case.
When loading an html, painting is suppressed in PresShell. Therefore the
rect of nsCaret or the rect of nearest ancestor scroll frames will not
be correct. Touch caret will hide incorrectly because it cannot get the
necessary rect to calculate its position.
I added a condition in IsDisplayable() to skip when painting is
suppressed. Touch caret should sync its visibility with nsCaret again
when painting is unsuppressed, and those rects needed by touch caret
should be ready then.
The forward declaration of Selection in nsCaret.h will be used in later patches.

This patch started an attempt to remove nsFrameSelection.h from nsCaret.h
and metastasized into a rather large refactoring patch that removed it
from some other header files as well, and changed nsFrameSelection::HINT
into a global-scope enum with better names. I also converted bools
into CaretAssociationHint in a few places where that was appropriate,
but there are still some more places (GetChildFrameContainingOffset)
where bools need to be converted. I figured this patch was big enough already.

GetGeometry is used in two different ways. Sometimes it's used to get
information about a particular caret. Sometimes it's used to get
information about a particular selection that's not associated with
a caret. Splitting GetGeometry into a non-static version for the former
and a static version for the latter makes this more clear. Also it saves
code since for the latter version we don't have to get an nsCaret first.

NS_WHEEL_EVENT_START isn't a specific event message for compairing in
the switch case. Since we would like to hide touch caret whenever
receving wheel events, all the wheel event types are added.
* Refactor UpdateTouchCaret() into smaller functions.
* Update touch caret in PresShell::DidDoReflow() and
PresShell::UnsuppressAndInvalidate() if needed.
* Refactor UpdateTouchCaret() into smaller functions.
* Update touch caret in PresShell::DidDoReflow() and
PresShell::UnsuppressAndInvalidate() if needed.
For touch events generated by marionette, the touch id is not started
from 0. Therefore, instead of getting the event position of touch id 0
directly in HandleTouchDownEvent(), we should loop over all the touch
ids to get their positions.
