lzeng14 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.

ydong10 fab1046560 Update for SecurityPkg.
Per UEFI spec, on CallBack action EFI_BROWSER_ACTION_CHANGING, the return value of ActionRequest will be ignored, but on CallBack action EFI_BROWSER_ACTION_CHANGED, the return value of ActionRequest will be used. 
But, EDKII browser still processes the got ActionRequest. And, all HII drivers in EDKII project also returns their expected ActionRequest value on action EFI_BROWSER_ACTION_CHANGING. 
Now update the browser to follow the spec, and update all core Hii drivers to keep old working modal.

oliviermartin 4d832aabbf SecurityPkg/VariableAuthenticated: Check if there is a NV Variable Storage header prior to use its attributes
The Variable PEI and RuntimeDxe drivers were using the attribute 'HeaderLength' of
EFI_FIRMWARE_VOLUME_HEADER without checking if a Firmware Volume Header was existing at
the base address.
In case the Firmware Volume Header does not exist or is corrupted, the attribute 'HeaderLength'
is a non valid value that can lead to a non valid physical address when accessing produces an
access error.
