This removes const qualification on data members of QConst*Data, which
was subjecting QString's and QByteArray's shared_null to the "order of
static initialization fiasco", with up-to-date VS 2010.
Furthermore, the const qualification in the places where it was removed
had little meaning and no value. It was unnecessary. As such, "Const"
was removed from the struct's names and "Static" used in its place, to
imply their usefulness in supporting statically-initialized fixed-size
(string and byte) containers.
A test case was added to QArrayData as that is meant to replace both
QStringData and QByteArrayData in the near future.

A reference count of 0 (zero) would never change. RefCount::deref to
zero would return false (resource should be freed), subsequent calls on
the same state would return true and not change state. While safe from
RefCount's side, calling deref on a reference count of zero potentially
indicated a dangling reference.
With this change, a reference count of 0 is now abused to imply a
non-sharable instance (cf. QVector::setSharable). This instance is to be
deleted upon deref(), as the data is not shared and has a single owner.
In practice, this means an (intentional) change in behaviour in that
deref'ing zero still won't change state, but will return false, turning
previous access to dangling references into double free errors.
Users of RefCount wanting to support non-sharable instances are required
to check the return of RefCount::ref() and use RefCount::isShared() to
determine whether to detach (instead of directly checking count == 1).
New functions are introduced to determine whether RefCount indicates a
"Static" (permanent, typically read-only) or "Sharable" instance and
whether the instance is currently "Shared" and requires detaching prior
to accepting modifications..
This change formalizes -1 as the value used to flag persistent,
read-only instances, no longer reserving the full negative domain. The
concrete value is part of the ABI, but not of the API. (isStatic and
Q_REFCOUNT_INITIALIZE_STATIC are part of the API, instead)

Inserting elements anywhere in the array requires moving the elements
that follow out of the way and writing in the new ones. Trivial for PODs
and almost as much for movable types.
For "complex" types, we start by extending the array with placement new
and copy constructing elements. Then, copy assignment resets the
elements that were previously part of the array.
QPodArrayOps uses non-throwing operations. QMovableArrayOps provides
full rollback in the face of exceptions (strong guarantee).
QGenericArrayOps enforces that no data is leaked (all destructors
called) and invariants are maintained on exceptions -- the basic
guarantee.
With 3 different implementations, 2 of which are non-trivial, this
operation is a good showcase for QArrayOpsSelector and the different
implementations. As such, it warrants its own commit.

Centralizing QArrayData memory management decisions in one place will
allow us to be smarter in how we allocate header and data.
At the moment, these are allocated as a single block. In the future we
may decide to allocate them separately for "large" data or specific
alignment requirements.
For users of QArrayData this remains transparent and not part of the
ABI. The offset field in QArrayDataHeader enables this.
This also hard-wires allocation of empty arrays to return shared_empty.
Allocating detached headers (e.g., to support fromRawData) will thus
require explicit support.

The capability flags indicate which information is valid in the touch
points. Previously there was no way to tell if e.g. the value returned
by pressure() is actually the value provided by the driver/device or
it is just something bogus due to pressure not being supported.
The points' flags return information about the individual touch
points. One use case is to differentiate between touches made by
finger and pen.
Velocity, if available, is now also exposed.
Each touch point can now contain an additional list of "raw"
positions. These points are not reported individually but are taken
into account in some way by the underlying device and drivers to
generate the final, "accurate" touch point. In case the underlying
drivers expose these additional positions, they are made available in
the lists returned by the touch points' rawScreenPosition().
The raw positions are only available in screen coordinates to prevent
wasting time with mapping from global positions in applications that
do not use this data. Instead, apps can query the QWindow to which the
touch event was sent via QTouchEvent::window() and can call
mapFromGlobal() manually if they need local raw positions.
The capability and device type information is now held in a new
QTouchDevice class. Each touch event will contain only a pointer to
one of the global QTouchDevice instances. On top of type and
capability, the new class also contains a name which can be used to
differentiate between multiple touch input devices (i.e. to tell from
which one a given QTouchEvent originates from).
The introduction of QTouchDevice has three implications: The
QTouchEvent constructor and QWindowSystemInterface::handleTouchEvent
need to be changed (to pass a QTouchDevice pointer instead of merely a
device type value), and each platform or generic plug-in is now
responsible for registering one or more devices using the new API
QWindowSystemInterface::registerTouchDevice.

Modeled on QByteArrayData/QStringData/QVectorData, the intent is to
unify book-keeping structs for array-like data and enable sharing of
code among them.
As in those structures, size (and alloc) data member(s) specify the
number of *typed* elements the array does (and can) hold. The size or
alignment requirements of those objects is not tracked in this data
structure and needs to be maintained by its users.
Contrary to QByteArrayData and QStringData, QArrayData's offset member
keeps a *byte* offset to the actual data array and is computed from the
beginning of the struct.
Shared-null and -empty functionality is provided by QArrayData and
shared among all users.
Planned features include setSharable (force deep copies), fromRawData
(detached header and data allocations) and literals a la QStringLiteral
(static immutable instances), thus covering the functionality needed for
QByteArray, QString and QVector.
