UnicodeStrToAsciiStrS/AsciiStrToUnicodeStrS.

The recent patch titled
IntelFrameworkModulePkg/GenericBdsLib: remove AcpiS3->S3Save() call
has exposed a preexistent bug in the BdsLibBootViaBootOption() function,
and now the IA32 build of OVMF fails with:
In function 'BdsLibBootViaBootOption':
error: 'Status' may be used uninitialized in this function
Namely, we have the following (simplified) data flow:
//
// Status and ImageHandle both start out uninitialized
//
/* ... */
ImageHandle = BdsExpandUsbShortFormDevicePath (DevicePath);
/* ... */
if (ImageHandle == NULL) {
/* ... */
}
if ((ImageHandle == NULL) || (EFI_ERROR(Status))) {
/* ... */
*/
If BdsExpandUsbShortFormDevicePath() returns a non-NULL value, then the
second "if" statement will check Status without the function having
initialized or assigned it.
When BdsExpandUsbShortFormDevicePath() returns non-NULL, Status should be
EFI_SUCCESS; so let us assign it that value up-front.
Note that the bug existed before the patch
IntelFrameworkModulePkg/GenericBdsLib: remove AcpiS3->S3Save() call
That is, the bug was not introduced, only exposed, by the patch -- in the
pre-patch state, although the Status variable was set early and
unconditionally, the error code that it may have carried from the failed
gEfiAcpiS3SaveProtocolGuid lookup had nothing to do with the second "if"
statement above.

The AcpiS3->S3Save() call needs to occur before the end-of-DXE event
is signalled. The end-of-DXE event needs to be signalled prior to
invoking any UEFI drivers, applications, or connecting consoles.
This means the call to S3Save() that occurs in BdsLibBootViaBootOption()
violates the ordering constraints, and should be removed. Since it is
the responsibility of the platform BDS to signal the end-of-DXE event,
it should also perform the AcpiS3->S3Save() call at an appropriate time.
Commit message update from Laszlo Ersek <lersek@redhat.com>:
Following Jiewen Yao's idea in
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16146
platforms that
(1) use this exact instance of GenericBdsLib, *and*
(2) support S3
should now collect the S3 state
(3) in an End-of-Dxe callback in their AcpiS3SaveDxe drivers, *or*
(4) with an explicit AcpiS3->S3Save() call made to their AcpiS3SaveDxe
drivers from their PlatformBdsLib instances.
OvmfPkg, which uses this GenericBdsLib instance, and has its own
AcpiS3SaveDxe fork, follows (3).
Vlv2TbltDevicePkg, which has a GenericBdsLib fork, and uses
IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe, follows (4).
There are no other platforms in the public edk2 repository that support
S3.

For PI spec vol3,
"EFI_SW_DXE_BS_PC_LEGACY_BOOT_EVENT The event with GUID EFI_EVENT_LEGACY_BOOT_GUID was signaled."
"EFI_SW_DXE_BS_PC_READY_TO_BOOT_EVENT The EFI_EVENT_GROUP_READY_TO_BOOT event was signaled."
However, in current code base, they are reported before events were signaled.

0. Remove the unused private GUID from module source files.
1. Use gEfiCallerIdGuid replace of the private module GUID.
2. Add the public header files to define HII FormSet and PackageList GUID used in every HII driver.
3. Publish EFI_LEGACY_DEV_ORDER_VARIABLE_GUID from BdsDxe driver and EFI_UPDATE_DATA_FILE_GUID from UpdateDriverDxe to IntelFrameworkModulePkg Include directory.
