Subject: Remove the dead code for blocking methods from QtConcurrent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After 79fd1cb2c631b6084bf10874205d27f5b53c907a the methods for running
QtConcurrent algorithms in the blocking mode aren't used anymore. Since
ThreadEngineBase and ThreadEngineStarter classes aren't meant to be used
externally, it should be fine to remove startBlocking() methods now.

Removed the unused code and adjusted the tests accordingly.
