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

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 (libSceNetCtlAp) - checks run in this order, which is not verified: a null structure returns INVALID_ADDR (0x80412991), a size field other than 152 or 184 INVALID_SIZE (0x80412998), then NOT_STARTED. The option string is not read, since the accepted strings (INVALID_OPT_STR, 0x80412901) are unknown. Whether sceNetCtlApStop of a stopped access point returns NOT_STARTED or 0 is unverified
sceNetCtlApClearEvent, sceNetCtlApGetResult (libSceNetCtlAp) - event types 1 to 4 are accepted and others return INVALID_TYPE (0x80412990), checked before the null errorCode (INVALID_ADDR). With no event ever delivered, sceNetCtlApGetResult writes 0; what the console writes before the first event is unverified
sceNetCtlApRegisterCallback, sceNetCtlApUnregisterCallback (libSceNetCtlAp) - a null function or id pointer returns INVALID_ADDR, a ninth registration CALLBACK_MAX (0x80412995), an id outside 0 to 7 INVALID_ID (0x80412996) and an unregistered id ID_NOT_FOUND (0x80412997). Ids are the lowest free slot, as in libSceNetCtl; the console's id assignment is unverified
