Granted, if the while-loop is not run, this means there is no memory
available at all on the computer where FreeLdr is running, which is
quite unexpected. But do the initialization anyways, in order to avoid
more obscure bugs down the line.
On the other hand, PageLookupTableMemAddress doesn't need to be
pre-initialized, since it gets initialized unconditionally afterwards.
Avoids dereferencing list entries to sections/items when these lists are empty.
IniParseFile(): Emit an error to the debug log when a candidate setting
is outside a section and skip it, instead of popping up an error on the UI.
This was a MinGW-specific, non-MS-DDK/WDK-compatible define, that was
used to mark NTOS kernel/hal exports, instead of NTSYSAPI etc.
We have since fixed that, and changed the way Freeldr (and rossym)
manages these, see commits:

Introduce the initial changes needed to get other processors up and into kernel mode.
This only supports x86 as of now but is the first real step towards using other system processors.
The newly implemented code for registry recovery makes the FreeLdr binary to grow
in size, to the point that it would BSOD because the PE image is too big.
For now we have to temporarily disable any of the newly added code, until
either FreeLdr is split into a basic PE bootloader image itself and a
"FreeLdrlib" that is used by the PE image to access various bootloader APIs
or another proper solution is found.
Validate the SYSTEM hive with CmCheckRegistry and purge volatile data with the same function when initializing a hive descriptor for SYSTEM.
Also implement SYSTEM recovery code that takes use of SYSTEM log in case something is fishy with the hive. If hive repair doesn't have fully recovered the SYSTEM hive, FreeLdr will load the alternate variant of the SYSTEM hive, aka SYSTEM.ALT.
If FreeLdr repairs the hive with a LOG, it will mark it with HBOOT_BOOT_RECOVERED_BY_HIVE_LOG on BootRecover field of the header. All the recovered data that is present as dirty in memory will have to be flushed by the kernel once it is in charge of the system.
Otherwise if the system boot occurred by loading SYSTEM.ALT instead, FreeLdr will mark HBOOT_BOOT_RECOVERED_BY_ALTERNATE_HIVE, the kernel will start recovering the main hive as soon as it does any I/O activity into it.

- Allow to boot NT kernel on UEFI systems with our 2 primary supported architectures
- Implement remaining code needed to pass execution to x86 and amd64 kernels
CORE-11954
Implement NTFS boot sector that loads FreeLdr from a NTFS partition.
CORE-17474
- Able to find/parse root directory;
- Handle fixups in FILE MFT record;
- Implement directory tree search;
- Implement loading found file from disk;
- Handle fixups in INDX records;
- Fail if compressed or sparse;
- Attempt to support 64-bit disks.
Some TO-DOs for later:
- Handle "weird" NTFS partition with uncommon sector sizes / sectors per cluster / sectors per index record;
- Better implementation for file loading;
- 64-bit LCN support.
In both lines 451 and 474:
uefidisk.c: warning C4553: '==': result of expression not used; did you intend '='?
It's "funny" that GCC builds doesn't catch those...
CORE-17604
- Disable some functions for ARM32;
- Remove some link options not used on ARM;
- Add get _controlfp() to LIBCNTPR to link properly on ARM;
- Unify Freeldr UI Drawing on ARM;
- Add qemu UART debugging for ARM32/ARM64.
CORE-11954
- EFI binaries have a different subsystem in the PE header;
- ENVIRON: Make sure INTN and UINTN are 64bit for 64bit platforms;
- Handle UEFI Memory maps and translate it for freeldr;
- Add FAILED_TO_EXIT_BOOTSERVICES Freeldr BSoD code.
First batch of changes to implement a UEFI version of freeldr:
- Compile freeldr as EFI binary on top of the existing loader.
- Stub out various functions so we can create a UEFI machine-type in freeldr.
- Implement all of the video output functions so we can display a pretty freeldr BSoD :)
- Keep the common definitions and file lists in CMakeLists.txt
- Move PC-AT & compatibles (PC-98, XBOX) definitions in pcat.cmake
- Future UEFI-specific definitions will be in an uefi.cmake
- Changed some wording according to the translation requirements.
- Fixed some mistakes.
- Changed my name.

Correct fix was to fix the HCELL_INDEX <-> HKEY conversions, much like
is being done with UlongToHandle / HandleToUlong.
The on-disk/in-memory hive file structures are platform-independent:
their layout must not depend on whether code is compiled in 32 or 64
bits.
