Possible simplification on Eclipse Luna

[felu]

CDT Luna will contain a fix that makes all cdt-indexer tests reliable. For cdttesting, this will allow to simplify indexer setup.

the setupIndex method of CDTProjectTest can then be reduced to:

private void setUpIndex() throws CoreException {
    // reindexing will happen automatically after call of setIndexerId
    CCorePlugin.getIndexManager().setIndexerId(cproject, IPDOMManager.ID_FAST_INDEXER);
    for (ICProject curProj : referencedProjects) {
        CCorePlugin.getIndexManager().setIndexerId(curProj, IPDOMManager.ID_FAST_INDEXER);
    }
    assertTrue(CCorePlugin.getIndexManager().joinIndexer(IIndexManager.FOREVER, new NullProgressMonitor()));
}

The checkTestStatus() method can be dropped entirely.
