Implement custom thread numbering for POSIX

Browse Source 
For every UNIX-derived (Android, Linux, macOS, iOS) flavor, a global counter is atomically incremented on thread start. That id is kept as thread-local storage.

Therefore, thread ids are sequential numbers, trivially comparable. This improves the previous state of things, in which `pthread_t` were casted to `Thread::ID` and unportabily compared. Also big, ugly thread ids appeared.
