Released v1.2.0

• Fixed: few BUGs related to AS-safety (Asynchronous Signals) .
• Change: td_wait_start(): removed timeout counter: unconditionally wait for all worker threads,
• Change: utt_BarrierInit(), utt_MutexInit(): return fault if target structure is already initialized,
• Added: utt_BarrierDestroy(), utt_MutexDestroy(): most likely those functions will never be needed in practice - added for completeness of the lib interface,
• Added: worker statistics: UTT_STAT_N_CONT: number of task continuation requests.
