This commit changes several instances where moc was generating code that
used 0 as a null pointer constant. The Q_NULLPTR define is the more
idiomatic way to do this, and additionally this silences warnings
generated by e.g. GCC's -Wzero-as-null-pointer-constant.
[ChangeLog][Tools][moc] Fixed "zero as null pointer constant" warnings
in moc's generated code.

The byte array literals are only used to append them to another
QByteArray, so they offer only the static size calculation as a
benefit.
However, there are several drawbacks:
- QByteArrayLiteral data cannot be shared the way string literals
can be, not even within a single TU, and they add a few ints
for the QByteArrayData header which cannot reside in BSS, but
need to be stored in DATA.
- QByteArrayLiteral *does* allocate when the compiler doesn't
support C++11 lambdas.
- QByteArrayLiteral, when not using RVO, litters the code with
QByteArray dtor calls, which are not inline, and thus can't
be optimized away.
In particular, when used like this, they do not prevent any
memory allocation (in fact, they might add some, absent lambdas).
So, just append (C) string literals.

When compiling with the -Wswitch-default flag, the compiler
spits warnings for the moc generated files.
In certain development environments (e.g. where MISRA rules
have to be followed) every switch statement needs to have a
default case. Unfortunately the moc generated files contain
switch statements without default case. This patch adds a
default statement to all switch statements that are generated
by the moc compiler.

When declaring a Q_PROPERTY(SomeType::SomeEnum foo ...) and SomeType is not a

list of related meta objects.

Assume an unrelated class that declares an enum and uses Q_ENUMS. Consider
then a class that uses UnrelatedClass::Enum as a Q_PROPERTY. We used to
include UnrelatedClass in the primary class's related meta objects, in order
to support use-cases like
obj->setProperty("enumProperty", "ValueOfEnumAsString");
If however moc happens to see Q_DECLARE_METATYPE(UnrelatedClass::Enum), then it
would exclude it from the related meta objects, which would silently break the
string based enum value conversion. This was meant as an optimization, but it
isn't apparent to the developer why sometimes the string conversion would
work and sometimes not (depending on whether somebody declares that macro).
This also becomes visible in QML, which relies on the same embedded type
information for enum assignments.
This patch removes that check in moc's code generator and cleans up the code a
little. However always including the prefix of Q_PROPERTY(SomePrefix::Enum ...)
is not correct either, because it may be that SomePrefix is a namespace, which
would cause compilation issues. Therefore we limit the inclusion of related
meta objects only to Q_OBJECT decorated classes the moc has seen, and for these
we save the fully qualified name in the related meta objects array (for QTBUG-2151).
While this patch makes the previous workaround for namespace issues by using a
Q_DECLARE_METATYPE not workable anymore, by saving the fully qualified name we
are making a hopefully sufficient effort to not require a workaround in the
first place. There's always the new workaround of fully qualifying the type in
Q_PROPERTY.
One side-effect of this change is that in the autoPropertyMetaTypeRegistration
test of tst_moc, the CustomQObject for Q_PROPERTY(CustomQObject::Number
enumValue ...) is now a related meta object, and therefore when querying for
the type of this property via QMetaProperty::userType(), we are now aware of
this being an enum and try to resolve CustomQObject::Number via
QMetaType::type(qualfiedName). As there is no guarantee for this to succeed, we
must now also do what is done in the non-enum code path in ::userType(), which
is to call the moc generated type registration function.

A module plugin in qml belongs to a URI/namespace. This
uri is resolved run-time by QtDeclarative by knowing the
path of the qmldir that references the plugin.
For static plugins this becomes a problem, since we lost
the information regarding which plugin belongs to which
qmldir, since a static plugin has no file path.
To avoid pushing the responsibility of clarifying this
onto the application developer, it is better to embed this
information into the meta data of the plugins themselves.
Since this information can be resolved by the
build system, a new option to moc has been added:
-M<key=value>
that will let you add meta tags to the meta data from
the command line to each class that has an IID specified.
For the URI case, we can then e.g do:
-Muri=QtQuick.Controls -Muri=QtQuick.Controls.Private

When encountering code such as:

(instead of being the operator<)
The type parser do not care about the actual type, it just need to strip
the string out. The problem is that then the whole rest of the file will
be considered as the type.
With this patch, we also stop the parsing at semicolon. The type will
be wrong, but this allow the parser to recover and it will continue to
look for more classes after this.
(In other words, moc will no longer break if it encounter such construct
in a header. But it will still not parse such types correctly if used
