Performance issues - FastDirectFieldAccessor

For FIELD access the relevant field is configured with field's
PropertyMetadata. That quite speeds the fields access.

A comaparison test for speed shows that we're faster than RI in
marshalling into XMLEventWriter, but slower when marshalling into
OutputStream - the reason is the internal use of XMLEvents - we should
soon do something about it.

And last thing - RI and Swe throws StackOverflow while marshalling +1000
nested attributes - maybe we should "flatten" the XML patterns?

Separating XSD and XML metadata in sws-bind

While constructing JAXBContext, we distinguish between XSD metadata
(needed to produce XML Schema and to validate instances) from the
metadata needed only for marshalling and unmarshalling operations.
