* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
* Improve sys_timer_get_information
* sys_timer_disconnect_event_queue sets STATE_STOP regardless of port connection status.
* sys_timer_get_information sets 0 for period and next_expire if the timer is stopped.
* Fix two minor races in lv2_timer thread
* If the timer thread is about to fire an event of queue x, then another thread disconnects the queue, then restarts the timer and connects the event queue, then the timer thread sends an event - event data combination (source, data1, data2, next) may be inaccurate.
* If the timer thread is about to send an event (periodically), then another thread stops the timer and starts it again with sys_timer_start_periodic_absolute, timer.expire in info->timer_state in sys_timer_get_information may be inaccurate.
* Hw tests show state is unaffected by external destruction of the event queue
* Minor race regarding state check fixed (can result in an undestroyable state)
- Matches ps3 accuracy for all tested values with few exceptions
- Do not enter the host OS kernel if waiting for less than 500us to avoid scheduler issues
* Optimizations
1) Some headers simplified for better compilation time
2) Some templates simplified for smaller executable size
3) Eliminate std::future to fix compilation for mingw64
4) PKG installation can be cancelled now
5) cellGame fixes
6) XAudio2 fix for mingw64
7) PPUInterpreter bug fixed (Clang)
* any_pod<> implemented
Aliases: any16, any32, any64
rsx::make_command fixed
