libSceCdlgG2P and libSceVrSetupDialog threw from every export. They now
run the common-dialog state machine libSceLoginDialog uses: Initialize,
Open, the status calls, GetResult, Close and Terminate follow it, the
dialog finishes at Open without showing anything, and GetResult reports
that the user cancelled, writing only the leading int32 result. The
signatures are assumed from the other common dialogs, as TechnicalDebt
records. 13 exports move from stubs to implemented.
