Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.
Fix operators == and <=> for synthesized rel-ops.
* 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")
* minor coding style adjustment
* Qt: simplify osk dialog buttons
* replace std::find_if with convenience functions
* RSX: use sv in swizzle comparison
idk, I'll remove this if it was intentional.
* overlays/osk: rename enter to return
This one confused me and make me look for a bug that caused the "enter" key to be disabled, while it was actually the return key (obviously xD).
I saw stvx v128{0} (aligned 16-bytes store) usage on the first 16-bytes of CellSaveDataCBResult before funcStat in fw.
Also I saw 4 stw of u32{0} on it as well before funcFile, funcFixed and funcList.
So just add the resets for result before all callbacks, and make all
members of savedata_ontext 16 -byte aligned in case there are more
members guaranteed to be aligned.
* Always memset 0 setBuf->buf (to bufSize) before funcStat if the direcory is not new.
* Always memset 0 setBuf->buf (to bufSize) if listGet->dirNum became non-zero (listGet->dirListNum can be zero yet memset still occurs) .
* Clear traces of setList setup before funcStat (after funcFixed/List, only if listGet->dirNum != 0, callback can hack this value and prevent the memset).
