/** @file
Function and Macro defintions for IFR parsing. To get the default value from IFR package, the IFR
opcode needs to be parsed. Most of code is taken from MdeModulePkg\Universal\SetupBrowserDxe\IfrParse.c.
This parser is simplified from the origianl IfrParser.c in the following way:
1) All data structure definition that have nothing to do with IFR Default value scanning (
required to implement Framework HII's GetDefaultImage ()) is removed.
2) Ignore the IFR opcode which is invalid for Form Package
generated using Framework VFR file.
