RAID drivers abstract their physical drives that make up
the array into a single unit, and do not supply individual
EFI_BLOCK_IO_PROTOCOL instances for each physical drive in the array.
This breaks support for the Security Storage Command Protocol,
which currently requires an EFI_BLOCK_IO_PROTOCOL to be associated
with the same device the protocol is installed on and provide
all the same parameters.
This patch remove dependency on EFI_BLOCK_IO_PROTOCOL and
allows access to Opal drive members of a RAID array.

Sets gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
to FALSE in OvmfPkgIa32.dsc, OvmfPkgIa32X64.dsc, and OvmfPkgX64.dsc
so that when SMM_REQUIRE is TRUE, the SMM variable driver will not
use the runtime variable cache.
This is done for OvmfPkg because it currently depends upon a SMM
variable GetVariable ()implementation as a simple method to exercise
the SMM driver stack. This allows the following commands to be used
for variables such as Boot####, BootOrder, and BootNext to test SMM

This change reduces SMIs for GetVariable () by maintaining a
UEFI variable cache in Runtime DXE in addition to the pre-
existing cache in SMRAM. When the Runtime Service GetVariable()
is invoked, a Runtime DXE cache is used instead of triggering an
SMI to VariableSmm. This can improve overall system performance
by servicing variable read requests without rendezvousing all
cores into SMM.
The runtime cache can be disabled with by setting the FeaturePCD
gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
to FALSE. If the PCD is set to FALSE, the runtime cache will not be
used and an SMI will be triggered for Runtime Service
GetVariable () and GetNextVariableName () invocations.
The following are important points regarding the behavior of the
variable drivers when the variable runtime cache is enabled.
1. All of the non-volatile storage contents are loaded into the
cache upon driver load. This one time load operation from storage
is preferred as opposed to building the cache on demand. An on-
demand cache would require a fallback SMI to load data into the
cache as variables are requested.
2. SetVariable () requests will continue to always trigger an SMI.
This occurs regardless of whether the variable is volatile or
non-volatile.
3. Both volatile and non-volatile variables are cached in a runtime
buffer. As is the case in the current EDK II variable driver, they
continue to be cached in separate buffers.
4. The cache in Runtime DXE and SMM are intended to be exact copies
of one another. All SMM variable accesses only return data from the
SMM cache. The runtime caches are only updated after the variable I/O
operation is successful in SMM. The runtime caches are only updated
from SMM.
5. Synchronization mechanisms are in place to ensure the runtime cache
content integrity with the SMM cache. These may result in updates to
runtime cache that are the same in content but different in offset and
size from updates to the SMM cache.
When using SMM variables with runtime cache enabled, two caches will now
be present.
1. "Runtime Cache" - Maintained in VariableSmmRuntimeDxe. Used to service
Runtime Services GetVariable () and GetNextVariableName () callers.
2. "SMM Cache" - Maintained in VariableSmm to service SMM GetVariable ()
and GetNextVariableName () callers.
a. This cache is retained so SMM modules do not operate on data outside
SMRAM.
Because a race condition can occur if an SMI occurs during the execution
of runtime code reading from the runtime cache, a runtime cache read lock
is introduced that explicitly moves pending updates from SMM to the runtime
cache if an SMM update occurs while the runtime cache is locked. Note that
it is not expected a Runtime services call will interrupt SMM processing
since all CPU cores rendezvous in SMM.
It is possible to view UEFI variable read and write statistics by setting
the gEfiMdeModulePkgTokenSpaceGuid.PcdVariableCollectStatistics FeaturePcd
to TRUE and using the VariableInfo UEFI application in MdeModulePkg to dump
variable statistics to the console. By doing so, a user can view the number
of GetVariable () hits from the Runtime DXE variable driver (Runtime Cache
hits) and the SMM variable driver (SMM Cache hits). SMM Cache hits for
GetVariable () will occur when SMM modules invoke GetVariable ().

The current VariableInfo application only checks for variable
statistics from SMM if the variable information entries are
not present in the UEFI System Configuration table as published
by the DXE UEFI variable driver (VariableRuntimeDxe).
This change first checks for variable information entries in the
UEFI System Configuration but always checks for entries in SMM
as well. If the SMM variable driver is not present, an instance of
EFI_SMM_VARIABLE_PROTOCOL will not be found and the search for
SMM variable statistics will be aborted (an SW SMI to get variable
statistics will not be triggered).
In the case variable statistics are provided by both a Runtime DXE
driver (e.g. VariableSmmRuntimeDxe) and a SMM driver (VariableSmm),
this change will clearly identify statistics from each respective
driver.

MpInitLib sets X2ApicEnable in two places.
1. CollectProcessorCount()
This function is called when MpInitLibInitialize() hasn't been
called before.
It sets X2ApicEnable and later in the same function it configures
all CPUs to operate in X2 APIC mode.
2. MpInitLibInitialize()
The X2ApicEnable setting happens when this function is called in
second time. But after that setting, no code consumes that flag.
With the above analysis and with the purpose of simplifying the code,
the X2ApicEnable in #1 is changed to local variable and the #2 can be
changed to remove the setting of X2ApicEnable.

Today's logic sets X2ApicEnable flag in each AP's initialization
path when InitFlag == ApInitConfig.
Since all CPUs update the same global data, a spin-lock is used
to avoid modifications from multiple CPUs happen at the same time.
The spin-lock causes two problems:
1. Potential performance downgrade.
2. Undefined behavior when improper timer lib is used.
For example we saw certain platforms used AcpiTimerLib from
PcAtChipsetPkg and that library depends on retrieving PeiServices
from idtr. But in fact AP's (idtr - 4) doesn't point to
PeiServices.
The patch simplifies the code to let BSP set the X2ApicEnable flag so
the spin-lock acquisition from AP is not needed any more.

This patch removes this assumption and supports constructing valid
paths for any value of FileName for the Root Directory.
In practice, this fixes compatibility issues with File System drivers

Note: we cannot use X509_VERIFY_PARAM_set1_ip_asc() because in the OpenSSL
