Yunus Shaikh 637b601bfb fix(libSceSaveData): restore a backup through a staged copy and roll back a failed swap ...

sceSaveDataRestoreBackupData used to remove the live save's files and
copy the backup over them, so a copy that failed half way left neither.
It now copies the backup, its .param and its blocks file to
_sd_restore_tmp/<dir>, checks that the copy has every entry at its size,
and flushes it. Then it moves the live save, .param and blocks file to
_sd_restore_old/<dir>, moves the staged copy into place and removes the
old one. A failed move puts back everything already moved, so the live
save stays as it was. The staging roots sit next to _sd, not in it,
where sceSaveDataDirNameSearch would list them.

SaveDataSetFileStepHook_nid_no_patch sets a function that is called
before each copy and rename of the backup and restore paths with a step
name and the path written; when it returns false that step fails. It
does nothing unless a test sets it.
