5e5bb2a9ba 1. Fix TOCTOU issue in VariableSmm, FtwSmm, FpdtSmm, SmmCorePerformance SMM handler. For VariableSmm, pre-allocate a mVariableBufferPayload buffer with mVariableBufferPayloadSize(match with mVariableBufferPayloadSize in VariableSmmRuntimeDxe) to hold communicate buffer payload to avoid TOCTOU issue. 
2. Add check to ensure CommBufferPayloadSize not exceed mVariableBufferPayloadSize or is enough to hold function structure in VariableSmm and FtwSmm.
3. Align FtwGetLastWrite() in FaultTolerantWriteSmmDxe.c to FtwGetLastWrite() in FaultTolerantWrite.c.

9d00d20ed4 1. Use the check IsAddressValid() to prevent SMM communication buffer overflow in SmmVariable, FtwSmm, FpdtSmm, SmmCorePerformance and SmmBaseHelper, and add check to prevent InfoSize overflows in SmmVariableHandler. 
2. Refine the debug message.
3. Add check to make sure the input VariableName is A Null-terminated string.
4. Use local variable to hold StrSize (VariableName) to avoid duplicated StrSize calculation.

23b0693579 1. Update the logic of UpdateVariable() for updating variable from: 
set old variable to IN_DELETED_TRANSITION -> check if reclaim is needed(If yes, do reclaim) -> add new variable -> set old variable to DELETED if no reclaim happened.
to:
set old variable to IN_DELETED_TRANSITION -> check if reclaim is needed(If yes, do reclaim) -> add new variable -> set old variable to DELETED.
2. Update UpdateVariable() to correctly handle the case "both ADDED and IN_DELETED_TRANSITION variable are present", and delete both old ADDED and IN_DELETED_TRANSITION variable when deleting or updating variable.
3. Update VariableServiceGetNextVariableName() to return the valid IN_DELETED_TRANSITION variable if only IN_DELETED_TRANSITION variable is present.

92a4f6f3c7 Add 64-bit versions of FLASH Base addressess as it is legal to have them >4G. For backward compatability if the new 64-bit base addresses are zero use the old 32-bit base addressess.

8e38f18ef7 variable driver doesn't support EFI_AUTHENTICATED_WRITE_ACCESS. we use: 
1. EFI_INVALID_PARAMETER as a return value of SetVariable() to indicate it does not support this feature.
2. EFI_NOT_FOUND will be a return value of QueryVariableInfo() to indicate it does not support this feature.

188e4e8444 Remove unnecessary use of FixedPcdxxx() functions and [FixedPcd] INF sections. These should only be used for PCDs that are used to pre-init global variables, pre-init global structures, or size arrays. 
Do some minor clean ups to INF files
