Replaces `std::shared_pointer` with `stx::atomic_ptr` and `stx::shared_ptr`.
Notes to programmers:
* This pr kills the use of `dynamic_cast`, `std::dynamic_pointer_cast` and `std::weak_ptr` on IDM objects, possible replacement is to save the object ID on the base object, then use idm::check/get_unlocked to the destination type via the saved ID which may be null. Null pointer check is how you can tell type mismatch (as dynamic cast) or object destruction (as weak_ptr locking).
* Double-inheritance on IDM objects should be used with care, `stx::shared_ptr` does not support constant-evaluated pointer offsetting to parent/child type.
* `idm::check/get_unlocked` can now be used anywhere.
Misc fixes:
* Fixes some segfaults with RPCN with interaction with IDM.
* Fix deadlocks in access violation handler due locking recursion.
* Fixes race condition in process exit-spawn on memory containers read.
* Fix bug that theoretically can prevent RPCS3 from booting - fix `id_manager::typeinfo` comparison to compare members instead of `memcmp` which can fail spuriously on padding bytes.
* Ensure all IDM inherited types of base, either has `id_base` or `id_type` defined locally, this allows to make getters such as `idm::get_unlocked<lv2_socket, lv2_socket_raw>()` which were broken before. (requires save-states invalidation)
* Removes broken operator[] overload of `stx::shared_ptr` and `stx::single_ptr` for non-array types.
* Do not wait on DEVICE 0x30 semaphore, it seems like it is something to do with queue command synchronization.
- This also fixes cellGcmSetFlipWithWaitLabel which is built specifically to enable accurate RSX flipping time, its waiting command is confirmed to be placed **AFTER** DEVICE 0x30 waiting.
* Fix default vsync state to be enabled. (and set it to enabled in cellGcmSetVBlankFrequency as well)
* Add experimental "Infinite" frame limiter mode.
* Fix spurious enabling of second vblank.
Turns out that both VBLANK time and flip time clock at 80Mhz which is MFTB rate, just that cellGcmGetLastFlipTime is missing conversion to microseconds, so odd.
* Use 2 points of known true RSX code roots and follow them in order to peek at the current section of valid RSX code:
These roots are: current RSX instruction address and the last targeted address by a branch instruction.
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")
* Allow emulation to work without firmware
* Fix HLE prx path detection.
* Fix manual list loading bugs.
* Fix HLE gcm
* GUI: Fix fonts search
* GUI: Hardcode sprx list
