This provides the same functionality as the specialized QStringLiteral
and QByteArrayLiteral, but on top of QArrayData.
The macro has two variations, variadic and simple. The variadic version
depends on compiler support for (C99) variadic macros and enables
static initialization of arrays of any POD data. Use of this macro is
not recommended on code or applications that need to work in
configurations where variadic macros are not supported.
The simple version is more portable and is enough to support the use
cases of QStringLiteral and QByteArrayLiteral, also providing a fallback
that allocates and copies data when static initialization is not
available.

By default, QTypedArrayData::fromRawData provides the same semantics as
already exist in QByteArray and QString (immutable, sharable data), but
more combinations are possible. In particular, immutable-unsharable
leaves the data owner in control of its lifetime by forcing deep copies.
As part of this, a new isMutable property is introduced in QArrayData.
This could be taken to be implicit in statics that are initialized with
a proper size but with alloc set to 0. QStringLiteral and QByteLiteral
already did this, forcing re-allocations on resize even before the
(static, thus shared) ref-count is considered.
The isMutable property detaches data mutability and shared status, which
are orthogonal concepts (at least in the unshared state). For the time
being, there is no API to explicitly (re)set mutability, but statics and
RawData mark data immutable.

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)

QVariant implementation is based on delegation to a handler. The handler
has rather simple construction, it is a set of function that implements
a switch statement over known types and redirects calls to a right
method of an encapsulated types instance. Unfortunately after qt
modularization project, it is not easy to use types directly from
different modules, as they can be undefined or completely unaccessible.
Which means that each module has to implement own handler to cooperate
correctly with QVariant. We can suspect that list of modules known to
QVariant will grow and it is not limited to GUI, Widgets and Core,
therefore it would be nice to have an unified, from performance and
source code point of view, way of working with handlers.
This patch is an attempt to cleanup handlers. Keynotes:
- Each handler is working only on types defined in the same module
- Core handler implements handling of primitive types too
- Custom types have an own handler
- Each handler is independent which means that dispatch between handlers
is done on QVariant level
- Handlers might be registered / unregistered using same interface
