HII Library Class interface refine.
The "HiiLib" prefix for all HII Library API function names changed to "Hii".
Remove:
HiiLibPreparePackageList(), replaced by HiiAddPackages()
HiiLibNewString(), replaced by HiiSetString()
HiiLibGetStringFromHandle(), replaced by HiiGetString()
HiiLibGetStringFromToken(), replaced by HiiGetPackageString()
HiiLibExtractGuidFromHiiHandle()
HiiLibDevicePathToHiiHandle()
HiiLibGetSupportedSecondaryLanguages()
HiiLibGetSupportedLanguageNumber()
HiiLibExportPackageLists()
HiiLibListPackageLists()
Interface change:
HiiAddPackages()
HiiSetString()
HiiGetString()
HiiGetHiiHandles()
