added: a deadlock counter to Synchro class

now we can use Lock() more than one in the same thread
       and next Unlock() will recognize it
       sample:
       Lock(); // first lock -- resources locked
       Lock(); // second lock -- skipped (counter incremented)
       ...
       Unlock(); // first unlock -- skipped (because counter greater than zero)
       Unlock(); // second unlock -- actually unlocking
