libSceNetCtlAp technical debt

libSceNetCtlAp (libSceNetCtlAp) - the access point never starts: a title starts it through libSceNetCtlApDialog, which always reports the user as having cancelled. sceNetCtlApGetState reports Stopped (0), sceNetCtlApGetInfo, sceNetCtlApGetConnectInfo and sceNetCtlApStop return NOT_STARTED (0x8041298F) without writing, and no callback ever fires. Signatures, states, structure sizes (152 and 184 bytes), the 8-callback limit and error codes come from SharpProspero

sceNetCtlApRegisterCallback (libSceNetCtlAp) - writing InvalidCid (-1) to cid when all eight slots are taken (CALLBACK_MAX) is unmeasured and interprets SharpProspero's comment that it is the value written into an unclaimed callback id, which does not name this path. libSceNetCtl and shadPS4 leave cid unchanged on a full table
sceNetCtlApInit, sceNetCtlApTerm (libSceNetCtlAp) - every other call returns NOT_INITIALIZED (0x80412994) before sceNetCtlApInit and after sceNetCtlApTerm, which also drops the registered callbacks. A second sceNetCtlApInit throws, as no error for it is documented
sceNetCtlApGetInfo, sceNetCtlApGetConnectInfo, sceNetCtlApStop - stopped-state results come from a service on the console and remain unverified. Wrapper validation is recovered: initialization precedes arguments, the optional connection string is at most eight bytes, then output pointers and exact 152/184-byte sizes are checked. The service interpretation of the option string remains unresolved.
sceNetCtlApGetResult - with no event delivered, the host writes zero; the service result before the first event remains unknown. Wrapper validation checks initialization, output pointer and event type in that order. Event types 1 through 4 and lowest-free callback IDs 0 through 7 are confirmed.
