Port the libSceDiscMap stubs from Kyty (InoriRus/Kyty, MIT) into the
SysAbiExport model. Disc-installed titles probe these NIDs on most file
accesses to decide whether a read must be redirected to the disc drive;
answering that every request is already resident on internal storage
keeps I/O on the regular file system path instead of failing with
unresolved-import errors.
- sceDiscMapIsRequestOnHDD (lbQKqsERhtE): validates args, writes 1 to
the result pointer, returns 0
- fJgP+wqifno / ioKMruft1ek: zero-fill the three output pointers,
return 0 (names not present in ps5_names.txt; kept as descriptive
Unknown exports like the existing sceKernelUnknown* convention)
- DISC_MAP_ERROR_INVALID_ARGUMENT (0x81100001) on null pointers,
matching the documented libSceDiscMap error range
- optional tracing via SHARPEMU_LOG_DISCMAP=1
