• Deprecated ThreadedMutex because ext-pthreads development halted (see krakjoe/pthreads#929)
• Deprecated ThreadedSemaphore because ext-pthreads development halted (see krakjoe/pthreads#929)
• Raised requirement to PHP 7.1

Removed usage of anonymous class in ThreadedMutex and ThreadedSemaphore, instead both now use an internal pre-defined class. Anonymous classes cannot be transferred to a thread, so previously they could not actually be used in a thread as intended… oops…

Initial release.
