[BB10-internal] Add a method that allows registration of files to types

There is currently no way in C++ to duplicate the functionality of a qmldir
file in mapping QML files to versioned types in a module. This functionality
would be useful both in cases where a separate qmldir file would be overkill,
and for cases where the type mapping should be generated dynamically.

Since public API is frozen for 4.8, this is being added as private API
for those who need some measure of compatibility with qtquick1 in Qt5.

[BB10-internal] Revert "Remove QPerformanceTimer now that QElapsedTimer contains the necessary bits"

This reverts commit 88966515993773e4d7d6276bce6fccfcc13ab6f4.

This apparently caused regressions in Cascades.

[BB10-internal] QSslConfiguration: toggle on demand loading of root certs properly

make sure we keep track of when we can load root certs and when we
cannot (we cannot when the developer set the certs explicitly). This is
implemented the same way for QSslSocket already, and needs to be
duplicated because we have 2 methods for setting CA certificates: one in
QSslSocket and one in QSslConfiguration.
In addition, adapt the auto test which checks whether setting a default
QSslConfiguration works: There is no way to set on demand loading
through the API, so it should be enabled by default.
