jljusten 02328a57a2 EMU Variable: Add support for pre-reserved NV variable store. 
Add PcdEmuVariableNvStoreReserved which allows a platform to declare a
memory address for the EMU Variable driver to use for the NV variable
store.  The EMU Variable driver will look to see if the contents of
this memory range appear to be a valid variable store, and if so
the EMU driver will use the variables.

If a platform can preserve a memory range across system resets, this
feature can allow the EMU Variable driver's NV variable store to be
preserved across a system reset.

In the default case this PCD will be set as a fixed PCD with a value
of 0.  In this case this new feature should have minimal impact on
the EMU Variable driver.  (Perhaps a slight increase in code size,
but no functional difference is expected.)

eric_tian bcd7070d86 fix the issue of Inadequate Memory Allocation in Variable Services 
In UpdateVariableInfo(), the code incorrectly allocate a small memory, whose size equate with the number of Unicode name. 
Should change it to be equal to the byte length of this Unicode name.

jljusten 51967a5314 Acquire & Release the lock from the high level variable service 
routines similar to MdeModulePkg/Universal/Variable/RuntimeDxe.
When the Acquire was in the FindVariable routine, is was
being called by both EmuSetVariable and again in
AutoUpdateLangVariable, which caused an ASSERT to fail.

jljusten bd682470fc Prefix variable services functions with 'Emu'. Specifically this is 
done to avoid a conflict with the 'GetVariable' function defined
in edk2/MdePkg/Include/Library/UefiLib.h.

eric_tian fba0ee1f4c Fix tracker 202216:linux runtime test issue. 
[Root Cause]
The root cause is that in FindVariable function, original code logic will traverse all variable stored in variable volatile/non-volatile area. If the non-variable area is full and Linux sets a new variable, the caller of GetNextVariablePtr will get the address of next memory block, but this block doesn't be reserved as RUNTIME attribute. Therefore its corresponding page translation table doesn't exist and causes linux kernel panic.

Note that, Variable Pei driver has not such issue as the flash area is accessed in pre-os environment.All page table entries are filled. The access to next memory block will not cause such issue.

eric_tian 5bb820af59 1. add missing free operation in conditional branch. 
2. when variable store header is invalid status, we will return EFI_VOLUME_CORRUPTED to let code assert, which is helpful to find root cause quickly.

eric_tian 3709c4cd5b 1. delete Include/Guid/VariableInfo.h 
2. move VariableFormat.h into GUID directory and change the “Signature” field of the VARIABLE_STORE_HEADER to gEfiVariableGuid value.
3. merging VARIABLE_INFO_ENTRY structure into the new Include/Guid/VariableFormat.h
4. change gEfiVariableInfoGuid into gEfiVariableGuid.
5. modify FDF files to use new guid value instead of the original signature.
6. all code related to signature is changed to use guid value.
