Socket waits now block in select() on the socket plus a wake or cancel socket (Common/Net/Cancel), so a stop or cancel ends them at once. - HTTP: cancel flags become net::CancelToken; Connect waits once on all addresses, receives wait instead of spinning, no DNS retry sleep. - Adhoc: the friend finder and adhoc server block on their sockets with a wake socket and a deadline; matching runs on a CoreTiming tick instead of two threads (savestate section bumped). - sceNetInet select/poll check without blocking and park the HLE thread, re-checked from a CoreTiming event until ready or the emulated timeout. - Vendor the aemu_postoffice client (was a submodule) with no sleeps: waits on the socket, close via shutdown and an eventcount, cancelable connects, and lock-free session slot claims. - PortManager waits without a timeout; PSP_InitWait replaces the headless boot poll. - TimeUtil: sleep_us/sleep_ms only outside the core; sleep_precise, sleep_random, yield and the Windows timer period are gone. - Unit test for the socket waits.
