* Fix a corner case where SPU thread has the same ID as a PPU thread.
* Fix a potential deadlock on Emu.Stop() while sending event in EBUSY loop.
* Thread specific notifications.
* sys_spu: Fix race in sys_spu_thread_group_destroy and other minor fixes
* SPU: Wait for all threads to have error codes if exited by sys_spu_thread_exit
On last thread in group to run.
* sys_spu: Fix sys_spu_thread_group_start
* fixup ad fix sys_spu_thread_group_terminate
idk why "- !group->running" was put in the first place but its probably no longer relevant due to other changes and was causing other issues such as not always waiting for last SPU thread to set group state to INITIALIZED.
'id' is not the idm id, also explicitly join the thread so a situation where the thread is still active and communicating other threads (e.g via MMIO or MFC) yet its ID is removed won't happen. (logic breakage, destroyed thread can't be active)
If name_len is 0 name is empty, in any other case name is not empty (attr->name == nullptr isn't allowed in this case).
Check name_len and option for invalid values as fw.
* Removed wrong code in sys_spu_thread_group_terminate.
* SPU Thread ID is accurate, including 5th thread id "rule".
* Fixed possible use-after-free access of spu_thread::group member.
* RawSPU ID management simplified.
Prefer vm::ptr<>::ptr over vm::get_addr.
Prefer vm::_ptr/base over vm::g_base_addr with offset.
Added methods atomic_t<>::bts and atomic_t<>::btr .
Removed obsolute rsx:🧵:Read/WriteIO32 methods.
Removed wrong check in semaphore_release.
Added handling for PUTRx commands for RawSPU MFC proxy.
Prefer overloaded methods of v128 instead of _mm_... in VPKSHUS ppu interpreter precise.
Fixed more potential overflows that may result in wrong behaviour.
Added io/size alignment check for sys_rsx_context_iounmap.
Added rsx::constants::local_mem_base which represents RSX local memory base address.
Removed obsolute rsx:🧵:main_mem_addr/ioSize/ioAddress members.
