The four account ID ranking calls take const std::uint64_t* account IDs,
but the test called them through the PcId calls' const void* type, which
clang's function sanitizer reports as undefined behaviour. They now use
a function type that matches their declarations.
Firmware 13.42 checks the option, a null comment or data, the request
and the comment length before queueing these to its worker, and checks
the mode and id of sceNpScoreChangeModeForOtherSaveDataOwners.
The 15 exports threw. They now keep title contexts and requests, run
shadPS4's argument checks in its order, and answer the record, ranking
and board calls with SCE_NP_ERROR_SIGNED_OUT, which also finishes the
request, as shadPS4 does for a user with no connection.
