Bret Barkelew f8e6bcb6e7 MdeModulePkg: Initialize temp variable in VarCheckPolicyLib
DumpVariablePolicy() will return EFI_INVALID_PARAMETER if the Buffer
pointer is NULL and the indirect Size is anything but 0. Since this
TempSize was not being initialized it is very likely that this sequence
would not return the total buffer size as expected.

Bret Barkelew 483449c9da MdeModulePkg: Define the VarCheckPolicyLib and SMM interface
https://bugzilla.tianocore.org/show_bug.cgi?id=2522

VariablePolicy is an updated interface to
replace VarLock and VarCheckProtocol.

This is an instance of a VarCheckLib that is backed by the
VariablePolicyLib business logic. It also publishes the SMM
calling interface for messages from the DXE protocol.
