system76-edk2/EdkCompatibilityPkg/Compatibility/FrameworkHiiToUefiHiiThunk/Package.c
qwang12 0368663fd6 Bug fixes for FrameworkHiiToUefiHiiThunk; 
1) Update variable name to better names.
2) Change List Entry in all data structure to "Link".
3) Update to use proper list manipulation functions in BaseLib.
4) Add in more comments and clean up HiiNewString.
5) Clean up for HiiNewPack, HiiRemovePack and the notify functions.
6) Create better name such as GetPackageCount and AssignFrameworkHiiHandle
7) Clean up the InitializeHiiDatabase entry point.
8) Remove the confusing data field in the HII_THUNK_ENTRY HiiDatabase.h.
9) Add in cleanup code for DestoryThunkContext
10) Add in code to handle the save of browser data after invoke callback 
11) Map the UEFI One Of Option code to Framework One Of Option code before calling Framework Callback.
12) Add in CreatePopUp support.
13) Add in SendForm support.
14) HiiGetPrimaryLanguages and HiiGetSecondaryLanguages should support language code in RFC639 format from Caller. Then, they should conver them to 3066 format before calling UEFI HII interfaces.
15) Make ResetStrings a NOP.
16) Remove the unnecessary dependency.
