* Use sleepthread in RPC loop
* Keep a pointer to current IOP thread
* Implement IOP thread scheduling based on priority
And implement DelayThread as an actual delay.
* Run IOP flat out
* Use information from scheduler in wait_run_iop
* Lock sif mutex in set_rpc_queue
* always use kernel dispatch with wait_run
* Loop in dispatch until no thread is ready
* Use timestamp for next wakeup
instead of duration
* Wrap IOP thread entrypoints for safety
Libco threads are not supposed to return from their entrypoint
* Use a queue for IOP thread wakeups from EE thread
* IopThreadRecord -> IopThread
* add libco
* Use cooperative threading for IOP threads
* Ugly solution for overlord start
Needs to run in a thread
* Clean out thread shutdown logic
* Update comments
* fix IOP getting stuck on music load
* fix regression? and clang
* fix a decomp
* fix another regression
* another
* fix "all actors"
* another regression!
