Introduce DEBUG_ON_HYPERVISOR_CONSOLE build flag to enable logging
debug output to the Xen console.
This will work with both Xen HVM guest and Xen PVH guest whereas the
default PlatformDebugLibIoPort works only in HVM when QEMU is present.

Remove support for DEBUG_ON_SERIAL_PORT because OvmfXen can't be build
with it due to a circular dependency:
DebugLib : BaseDebugLibSerialPort ->
SerialPortLib : XenConsoleSerialPortLib ->
XenHypercallLib : XenHypercallLib ->
DebugLib
Also, if that dependency is fixed, I think it would be harder to find
which console the debug is sent to when running an HVM guest. The xen
console isn't the serial console used by default. Furthermore,
XenHypercallLib isn't initialised early enough, so we would loose
debug output from the SEC phase and early PEI phase.

Both PEI and DXE instances of the MpInitLib are using PcdLib APIs, but
none of them list the dependency of the PcdLib in INF & header files.
This commit will explicitly add such dependency in .H and .INF files.

If FV is placed in FD region, its FV image size is fixed.
When FV image size exceeds it, it will trig the build break.
To alert the developer to adjust FV image size earlier,
I request to add new checker for the the spare FV space.
When the spare FV space is less than the specified threshold,
build tool will report the error.
This checker is the optional.
It can be enabled by -D FV_SPARE_SPACE_THRESHOLD=10000.
Macro is the value of the spare space threshold size.
It can be decimal or hex format. If it is enabled,
BaseTools will check every FV with the fixed size.
If FV doesn't meet with the size requirement,
Build tool will report error message to say there is no
enough spare space.

The BaseResetSystemLib instance is not suitable for OS runtime, because
its ResetShutdown() implementation calls PciRead16 (OVMF_HOSTBRIDGE_DID).
On q35, this boils down to a memory-mapped config space access -- but we
never ask the OS to map MMCONFIG for runtime.
There are at least three alternatives to approach this:
(1) Investigate "MdePkg/Library/DxeRuntimePciExpressLib", which offers
some kind of runtime mapping for MMCONFIG.
(2) Consume PciCf8Lib directly, rather than PciLib, in ResetSystemLib.
Then we'll read OVMF_HOSTBRIDGE_DID from the config space with IO port
accesses on q35 too, not just on i440fx. IO ports don't depend on page
tables.
(3) In the lib constructor, cache "mAcpiPmBaseAddress" based on
"PcdOvmfHostBridgePciDevId" (which is set by PlatformPei). Then the
host bridge type will be known at runtime without PCI config space
accesses.
This patch follows approach (3), in order to mirror AcpiTimerLib.
Notes:
* This patch is best viewed with "git show --find-copies-harder -C43".
* PCDs are not usable in the DXE_CORE, as the PCD PPI is gone, and the PCD
protocol is not available yet. (The DXE_CORE does consume ResetSystemLib
in practice, when OVMF is built with -D SOURCE_DEBUG_ENABLE.)

[lersek@redhat.com: move third Note (with repro info) to BZ comment]
Move the ResetShutdown() definition to its own file. This will help us
introduce:
- a new library instance that is not broken in runtime modules (the
current library instance is broken in runtime modules),
- another new library instance for bhyve support.
While at it, squash AcpiPmControl() into ResetShutdown(), open-coding
SuspendType=0. This is justified because we've had no other callers for
AcpiPmControl() since commit 2d9950a2bf ("OvmfPkg: remove
EnterS3WithImmediateWake () from ResetSystemLib", 2020-01-10).
Tested with the "reset -s" UEFI shell command, on both i440fx and q35.

Annotate the #include directives with the interfaces that this lib
instance needs from the included lib class headers. This will help us keep
the #include set minimal, when we move code around later.
While at it, synchronize the [LibraryClasses] section with the #include
directives -- list BaseLib.
Also #include the ResetSystemLib class header, which declares the
interfaces that this lib instance implements.
This forces us to spell out the "MdeModulePkg.dec" dependency too, under
[Packages].

Set the default value of PcdAcpiExposedTableVersions for Aarch64
platforms to 0x20. Previously, the default was set to 0x3E for all
platforms. The new value removes ACPI 1.0b compatability, which forces
the use of XSDT 64-bit pointer, as required by Arm SBBR specification.
This also resolves an error reported by acpiview command, as seen on
the RPi (see https://github.com/pftf/RPi4/issues/25).

ReportDispatcher() is called by a software module to report a status code.
The interface is generic and can be called frequently throughout the boot
under various conditions. A certain set of conditions can cause the
currently implemented algorithm for resource exhaustion to fail. A sample
scenario:
1. ReportStatusCode() is called at a TPL higher than one of the registered
status code listeners making the call to the listener deferred until
TPL is lowered.
2. Additional calls to ReportStatusCode() occur, so the data buffer
continues to expand.
3. A call to ReportStatusCode() is made from within a memory allocation
call (e.g. CoreAllocatePoolPages ()) which is protected from re-
entrancy with mPoolMemoryLock. This will cause the ReallocatePool()
call in ReportDispatcher() to fail. Because the end pointer was already
moved to account for the data size, the end pointer is now moved
beyond the buffer and invalid.
This commit saves the original end pointer value into a local variable
called "FailSafeEndPointer" which tracks a safe end pointer to revert to
in the case the allocated buffer size (CallbackEntry->EndPointer -
CallbackEntry->StatusCodeDataBuffer) is still not large enough for the
data.

The current SnpDxe implementation registers its ExitBootServices event
notification function (SnpNotifyExitBootServices ()) at TPL_NOTIFY. This
function calls PxeShutdown() which issues an UNDI shutdown operation.
Ultimately, this may invoke Shutdown() in EFI_SIMPLE_NETWORK_PROTOCOL.
The UEFI specification 2.8A Table 27 "TPL Restrictions" restricts the
TPL
for Simple Network Protocol to <= TPL_CALLBACK. In addition, it has been
observed in some 3rd party UNDI drivers to cause an issue further down
the call stack if the TPL is higher than TPL_CALLBACK on invocation.
Therefore, this commit changes the TPL of SnpNotifyExitBootServices() to
TPL_CALLBACK.

FieldElements can be one of the following:
NamedField | ReservedField | AccessField |
ExtendedAccessField | ConnectField
Some of these keywords are starting with an opcode,
allowing to identify their type.
E.g.: ReservedField := 0x00 PkgLength
This patch adds these FieldElement opcodes definitions to
