Star Zeng 3e02ebb2bb MdeModulePkg: Variable drivers robustly handle crashes during Reclaim(). 
PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid.
Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.

lzeng14 f07268bd0f Mallicious code may use SmmFaultTolerantWriteHandler() to update some flash area directly, like Variable region, so return EFI_ACCESS_DENIED after End Of Dxe in SmmFaultTolerantWriteHandler(). 
And add code to prevent InfoSize overflow.
