Enable running sql model tests in parallel

Each model test gets its own temporary directory, thus there is no problem parallelizing them.

This should reduce the time spent for a testrun of qtbase by around 3 minutes.
When running only the sql tests it saves less since there are no other tests to run in parallel.

QPlainTextEdit: set Qt::ImhMultiLine

Like QTextEdit, QPlainTextEdit should also set the
input method hint Qt::ImhMultiLine.
An important reason for this, is that the iOS plugin
will inspect the input method hints of the focus
object to decide which type of keyboard (and return
key) to use. Failing to set this hint will result
in the iOS plugin setting the return key to 'done'
instead of 'return' for this widget.

Also register complex D-Bus types when running under qdbus

When running inside qdbus, we generate the meta objects a little
differently. Previously, for unknown types we'd simply have a -1 as the
type ID in the meta object, but this doesn't work in Qt 5 (has
apparently never worked). So simply register a type with the metatype
system and let QMetaObject do its thing.

[ChangeLog][qdbus]Fixed a bug that caused the qdbus tool to crash
when trying to display remote interfaces that had complex types
without a matching base Qt type.
