Currently some tests check the value of SOURCE_DEBUG_ENABLE, and some
tests check if it's defined or not. Additionally, in UefiPayloadPkg as
well as some other trees, we define it as FALSE in the .dsc file.
This patch changes all of the Ovmf platforms to explicitly define it as
FALSE by default, and changes all of the checks to test if the value is
TRUE.

Independently of how we decide to address other aspects of the regression
introduced with commit 2de1f611be, it doesn't
make much sense to call for a progress update if PcdPlatformBootTimeOut is
zero.
PcdPlatformBootTimeOut 0, which is the cause of the bug (division by zero)
should be considered to indicate that a platform is not interested in
displaying a progress report, so we alter PlatformBootManagerWaitCallback
to behave that way.
We also change one variable name to make the code more explicit.

In the following call tree:
PlatformInit ()
mInstalledPackages = HiiAddPackages ()
GopInstalled ()
PopulateForm (PackageList = mInstalledPackages)
CreateResolutionOptions (PackageList)
HiiSetString (PackageList
HiiUpdateForm (PackageList)
PlatformDxe passes around an EFI_HII_HANDLE that (a) originates from
HiiAddPackages() and (b) is ultimately passed to HiiSetString() and
HiiUpdateForm(). The intermediate functions PopulateForm() and
CreateResolutionOptions() however take that parameter as an
(EFI_HII_HANDLE*).
There is no bug in practice (because the affected functions never try to
de-reference the "PackageList" parameter, they just pass it on), but the
function prototypes are semantically wrong. Fix that.
This could remain hidden so long because pointer-to-VOID silently converts
to/from any pointer-to-object type, and the UEFI spec mandates that
EFI_HII_HANDLE be a typedef to (VOID*).

The SignalEvent() boot service takes an EFI_EVENT, not an (EFI_EVENT*).
Fix the call in the notification function of
"EFI_SIMPLE_NETWORK_PROTOCOL.WaitForPacket".
This is an actual bug. The reason it's never been triggered is likely that

On a Xen PVH guest, none of the existing serial or console interface
works, so we add a new one, based on XenConsoleSerialPortLib, and
implemented via SerialDxe.
That is a simple console implementation that can work on both PVH
guest and HVM guests, even if it is rarely going to be used on HVM.
Have PlatformBootManagerLib look for the new console, when running as a
Xen guest.
Since we use VENDOR_UART_DEVICE_PATH, fix its description and coding
style.

When running as a Xen PVH guest, there is no CMOS to read the memory
size from. Rework GetSystemMemorySize(Below|Above)4gb() so they can
work without CMOS by reading the e820 table.
Rework XenPublishRamRegions to also care for the reserved and ACPI
entry in the e820 table. The region that was added by InitializeXen()
isn't needed as that same entry is in the e820 table provided by
hvmloader.
MTRR settings aren't modified anymore, on HVM it's already done by
hvmloader, on PVH it is supposed to have sane default. MTRR will need
to be done properly but keeping what's already been done by programs
that have run before OVMF will do for now.

The ACPI Timer isn't present in a PVH guest, but local APIC works on
both PVH and HVM.
Note that the use of SecPeiDxeTimerLibCpu might be an issue with a
driver of type DXE_RUNTIME_DRIVER. I've attempted to find out which of
the DXE_RUNTIME_DRIVER uses the TimerLib at runtime. I've done that by
replacing the TimerLib evaluation in
[LibraryClasses.common.DXE_RUNTIME_DRIVER] by a different one and
checking every module that uses it (with the --report-file=report
build option).
ResetSystemRuntimeDxe is calling the TimerLib API at runtime to do the
operation "EfiResetCold", so this may never complete if the OS have
disabled the Local APIC Timer.

This patch allows the ResetVector to be run indenpendently from build
time addresses.
The goal of the patch is to avoid having to create RAM just below 4G
when creating a Xen PVH guest while being compatible with the way
hvmloader currently load OVMF, just below 4G.
Only the new PVH entry point will do the calculation.
The ResetVector will figure out its current running address by creating
a temporary stack, make a call and calculate the difference between the
build time address and the address at run time.
This patch copies and make the necessary modification to some other asm
files:
- copy of UefiCpuPkg/.../Flat32ToFlat64.asm:
Allow Transition32FlatTo64Flat to be run from anywhere in memory
- copy of UefiCpuPkg/../SearchForBfvBase.asm:
Add a extra parameter to indicate where to start the search for the

This patch changes the flash device image of OvmfXen to make it look
like it's an ELF. For this, we replace the empty embedded variable store
by a binary array, which is a ELF file header.
The ELF header explain to a loader to load the binary at the address
1MB, then jump to the PVH entry point which will be created in a later
patch. The header also includes a Xen ELF note that is part of the
PVH ABI.
That patch include OvmfXenElfHeaderGenerator.c which can be use to
regenerate the ELF header, but this will be a manual step.

Introduce XenPlatformPei, a copy of OvmfPkg/PlatformPei without some
of QEMU specific initialization, Xen does not support QemuFwCfg.
This new module will be adjusted to accommodate Xen PVH.
fw_cfg dependents that have been removed, which are dynamically skipped
when running PlatformPei on Xen:
- GetFirstNonAddress(): controlling the 64-bit PCI MMIO aperture via the
(experimental) "opt/ovmf/X-PciMmio64Mb" file
- GetFirstNonAddress(): honoring the hotplug DIMM area
("etc/reserved-memory-end") in the placement of the 64-bit PCI MMIO
aperture
- NoexecDxeInitialization() is removed, so PcdPropertiesTableEnable and
PcdSetNxForStack are left constant FALSE (not set dynamically from
fw_cfg "opt/ovmf/PcdXxxx")
- MaxCpuCountInitialization(), PublishPeiMemory(): the max CPU count is
not taken from the QemuFwCfgItemSmpCpuCount fw_cfg key;
PcdCpuMaxLogicalProcessorNumber is used intact and
PcdCpuApInitTimeOutInMicroSeconds is never changed or used.
- InitializeXenPlatform(), S3Verification(): S3 is assumed disabled (not
consulting "etc/system-states" via QemuFwCfgS3Enabled()).
- InstallFeatureControlCallback(): the feature control MSR is not set
from "etc/msr_feature_control"
(also removed FeatureControl.c as there is nothing been executed)
Also removed:
- SMRAM/TSEG-related low mem size adjusting (PcdSmmSmramRequire is
assumed FALSE) in PublishPeiMemory(),
- QemuInitializeRam() entirely,
Xen related changes:
- Have removed the module variable mXen, as it should be always true.
- Have the platform PEI initialization fails if Xen has not been
detected.
