There is no reason to keep two separated core types sets. It
couldn't be fixed before Qt5 because of binary compatibility promise.
This patch merges QMetaType core types with ext core types.
This "simple" operation consists of:
- QDataStream version was incremented, because type ids are
saved in QVariant's data stream.
- QMetaType LastExtCoreType and FirstExtCoreType were replaced by
LastCoreType, FirstCoreType and new QMetaType::HighestInternalId.
- New tests checking QVariant data stream for Qt4 and for Qt5 versions
were added.

This is a source incompatible change for Q_DECLARE_METATYPE(T*),
which now requires T to be fully defined.
The consequences of this are:
* Forward declared types can no longer be declared as a metatype.
(though this is a very uncommon thing to do).
There is a trivial workaround where necessary.

It isn't necessarily that hashing the whole string is the main problem, as the

purpose of this benchmark is rather voided.
This removal allows gradually repurposing the test towards providing general

This uses a similar runtime to the approach of sampling part of the string, with
the benefit that it doesn't reduce the sampling to subsections of the string.
Ironically, Java used to only sample parts of the string as well, but found that
it produced too many collisions with certain string types, so they moved to use
this method.
