This patch defines two constants kSelectionTypeCount and kPresentSelectionTypeCount. The former is same as nsISelectionController::NUM_SELECTIONTYPES. The latter is kSelectionTypeCount - 1 for excluding SELECTION_NONE. The latter is useful in some loops which handle all selection types except SELECTION_NONE.
Note that this patch fixes a bug of nsFrameSelection. That doesn't treat SELECTION_NONE as a selection (see the definition of index), however, it defines redundant item and doesn't use it actually. Additionally, it computes invalid selection type in each loop. Therefore, without this patch, debug build hits MOZ_ASSERT() in ToSelectionType(RawSelectionType).
Note that these constants are defined as anonymous enum because we cannot define as const (or static) even with extern. If we'd try to do it, it caused link error or not available in nsFrameSelection.cpp as constant value since they were not initialized if they were initialized in nsSelection.cpp. Therefore, these constants are defined as enum items but using "k" prefix.

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.

mozilla::SelectionType will be an enum class. Therefore, we need to rename SelectionType with a word "raw" since it's a type for raw nsISelectionController::SELECTION_*.

nsCaret::GetFrameAndOffset may return a text frame also when aParentNode
is the container of a text node and aOffset is just after it. In this
case we also want CARET_ASSOCIATE_AFTER if the text ends with
a significant newline. (follow-up from bug 1258308)
Pings are sent in the implementations of the nsISelectionController methods
ScrollLine, ScrollPage, ScrollCharacter, and CompleteScroll. It is assumed
that these methods are triggered by keyboard input.
A small number of false positives can occur if these methods are called
in response to something other than keyboard input; this is considered
acceptable.
All the files modified are straightforward deletion except TouchManager
and ZoomConstraintsClient. I add some includes and wrap TouchManager by
mozilla namespace to fix build errors due to the removal of TouchCaret.

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.
CLOSED TREE makes big refactorings like this a piece of cake.
