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.
This was a flawed concept due to risk of deadlocks.
Worst case some we will focus o performanc regressins indvidually as we should and not accept this bug.
In real PS3 (it seems), when a thread with a higher priority than the caller is signaled and that there is available space on the running queue for the other hardware thread to start It prioritizes signaled thread caller's hardware thread switches instantly to the new thread code while signaling to the other hardware thread to execute the caller's code.
Resulting in a delay to the caller after such thread is signaled
Fix and optimize sys_ppu_thread_yield
Fix LV2 syscalls with timeout bug. (use ppu_thread::cancel_sleep instead)
Move timeout notification out of mutex scope
Allow g_waiting timeouts to be awaked in scope
Hitherto the statistics have been exclusively thread-specific.
Other improvements:
* Fixed container management so a collision of a new element with an older element of the record will become impossible.
* Added thread name to thread-specific information printing.
* Fixed condition to abort SPU block statistics collection, now matches SPU LLVM Profiler's.
* Fix possible division by 0 by checking `samples`.
