The patch uses CoreAcquireLockOrFail() instead of
CoreAcquireProtocolLock() in CoreLocateProtocol() to avoid
assertion when CoreLocateProtocol() is called with the
protocol database locked.
The issue was found when changing PcdDebugPrintErrorLevel to
enable page/pool allocation debug message.
Nt32 platform hangs immediately after DxeCore is loaded.
Investigation shows the following calling stacks:
DxeCore entry point (Install a certain protocol)
0 DxeCore::CoreInstallProtocolInterface // Protocol DB is locked
1 DxeCore::AllocatePool
2 PeiDxeDebugLibReportStatusCode::DebugPrint
3 DxeReportStatusCodeLib::ReportStatusCodeEx // <-------------------|
4 DxeReportStatusCodeLib::InternalGetReportStatusCode |
5 DxeCore::LocateProtocol(StatusCodeRuntimeProtocol) |
// Assertion when locking Protocol DB 2nd time |
6 DxeCore::CoreAcquireProtocolLock |
7 PeiDxeDebugLibReportStatusCode::DebugAssert |
8 DxeReportStatusCodeLib::ReportSatusCodeEx // loop begins ---------
In frame #6 the assertion is triggered due to the protocol database
is already locked. #8 calls #4 and the loop begins.
After changing #6 to CoreAcquireLockOrFail(), the assertion is
avoided and the loop is broken.
With the fix, NT32 can boot to Shell even setting
PcdDebugPrintErrorLevel to 0xFFFFFFFF, with all error levels turned
on.

When the DXE core is loaded, it invokes the PeCoffExtraActionLib library
function 'PeCoffLoaderRelocateImageExtraAction' explicitly, which may be
in addition to the same function having been called by the DxeIpl PE/COFF
loader instance.
The ImageContext that DXE core presents to this function is only partially
initialized, which may result in the following output on AArch64 systems:
add-symbol-file ..MdeModulePkg/Core/Dxe/DxeMain/DEBUG/DxeCore.dll 0x5F226240
<some intermediate output>
add-symbol-file ..MdeModulePkg/Core/Dxe/DxeMain/DEBUG/DxeCore.dll 0x5F226000
This is caused by incorrect data in the ImageContext structure, which means
the start of the .text section is calculated incorrectly. In general, it is
the duty of the caller to present a valid ImageContext structure, so let's
add the missing values before invoking PeCoffLoaderRelocateImageExtraAction().
