This is the minimal change required to stop exposing the EFI properties
table, which is deprecated. Given how the implementation is entangled
with the code that exposes the related memory attributes table, most of
the code is retained, and further cleanups are relegated to subsequent
patches.

Current UpdateCapsule service will reject all non-reset capsule images and
return EFI_OUT_OF_RESOURCE if the system is at runtime. This will block a
platform CapsuleLib from implementing ProcessCapsuleImage() with runtime
capsule processing capability.
This patch removes this restriction. The change is controled by a feature
PCD PcdSupportProcessCapsuleAtRuntime, and the default value is FALSE
which means not enable this feature.

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 ().

UAF (Use-After-Free) memory issue is kind of illegal access to memory
which has been freed. It can be detected by a new freed-memory guard
enforced onto freed memory.
BIT4 of following PCD is used to enable the freed-memory guard feature.
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask
Please note this feature is for debug purpose and should not be enabled
in product BIOS, and cannot be enabled with pool/page heap guard at the
same time. It's disabled by default.

This cleanup is meant for avoiding misuse of newly introduced BIT4
(UAF detection) of PCD PcdHeapGuardPropertyMask, because it applies
to all types of physical memory. In another words,
PcdHeapGuardPoolType and PcdHeapGuardPageType don't have effect to
the BIT4 of PcdHeapGuardPropertyMask.

BZ#1116: https://bugzilla.tianocore.org/show_bug.cgi?id=1116
The usage of following PCDs described in MdeModulePkg.dec don't match
the implementation exactly. This patch updates related description in
both .dec and .uni files to avoid confusion in platform configuration.
PcdSetNxForStack
PcdImageProtectionPolicy
PcdDxeNxMemoryProtectionPolicy
The main change is at the statement on how to handle the FALSE or 0
setting value in those PCDs. Current statement says the implementation
should unset or disable related features but in fact the related code
just do nothing (leave it to AS-IS). That means the result might be
disabled, or might be not. It depends on other features or platform
policy.
For example, if one don't want to enforce NX onto stack memory, he/she
needs to set PcdSetNxForStack to FALSE as well as to clear BIT4 of
PcdDxeNxMemoryProtectionPolicy.

The change is part of requirement tracked by #BZ1095
https://bugzilla.tianocore.org/show_bug.cgi?id=1095
Background:
Heap Guard and NULL Pointer Detection are very useful features to detect
code flaw in EDK II. If an issue is detected, #PF exception will be
triggered and the BIOS will enter into dead loop, which is the default
behavior of exception handling. From QA perspective, this default behavior
will block them to collect all tests result in reasonable time.
The solution is to introduce non-stop mode to Heap Guard and NULL Pointer
Detection features. This needs to update CpuDxe, PiSmmCpuDxeSmm and
CpuExceptionHandlerLib to allow the code to continue execution after #PF.
The mechanism behind it is the same as SMM Profile feature, in which a
special #PF handler is registered to set the page causing #PF to be
'present' and setup single steop trap, then return the control back to
the instruction accessing that page. Once the instruction is re-executed,
a #DB is triggered and a special handler for it will be called to reset
the page back to 'not-present'.
The non-stop mode is controlled by BIT6 of following PCDs
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask
gEfiMdeModulePkgTokenSpaceGuid.PcdNullPointerDetectionPropertyMask
BIT6 of PcdHeapGuardPropertyMask is used to enable/disable non-stop mode
of Heap Guard feature. It applies to both UEFI and SMM heap guard, if
any of them is enabled.
BIT6 of PcdNullPointerDetectionPropertyMask is used to enable/disable
non-stop mode of NULL Pointer Detection feature. It applies to both
UEFI and SMM NULL Pointer Detection, if any of them is enabled.
The default setting is 'disable', meaning the boot will stop at #PF
exception.
