If a macro is used with too few parameters, complaining about its
definition using '#' followed by something other than a macro
parameter name is apt to be confusing - reading the definition will
reveal that the name in fact is a macro parameter after all. The
reader needs attention directed to the invocation, not the definition.
Split the test in two: one to test the prior error message does in
fact get produced for an invalid macro definition, the other to test
the invalid invocation case.

GCC 5 combined with a recent binutils have a new optimization that
allows them to generate copy relocations even in -fPIE code. Clang has
the same functionality when compiling an executable with -flto. We need
to let the compilers know that they cannot use copy relocations, so they
need to use really position-independent code.
Position independent code throughout is not really required. We just
need the compilers to use position-independent access to symbols coming

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

With this patch, we also stop the parsing at semicolon. The type will
