- During loading and initialization of the list of operating systems
available in freeldr.ini, convert any legacy operating system entry
encountered -- they are like those in NTLDR's boot.ini file, i.e.:
ArcOsLoadPartition="LoadIdentifier" /List /of /Options
into a new operating system INI entry, like those used by default in
FreeLoader. This allows us to avoid treating this corner-case later in
different parts of the code. Also, the "BootType" value is now
determined there, only once.
- Convert the OS loaders entry-points to ARC-compatible ones, following
the "Advanced RISC Computing Specification, Version 1.2" specification
https://www.netbsd.org/docs/Hardware/Machines/ARC/riscspec.pdf
- Introduce helpers for retrieving options values from the argument vector
in a simple way.
- Simplify LoadOperatingSystem(), since now the "BootType" value has
been determined once while loading the list of OSes (see above) and
is well-defined there. Use the BuildArgvForOsLoader() helper to build
the ARC-compatible argument vector from the corresponding INI settings
for the selected operating system entry, and use it when calling the
corresponding OS loader.
- In the OS loaders, since we can now directly read the settings from
the argument vector (instead of using INI settings), we can avoid
using a bunch of fixed-size string buffers, and avoid potentially
failing IniOpenSection() calls as well.
- Simplify code in the Linux loader (and the RemoveQuotes() function).
- Add UiShowMessageBoxesInArgv() that acts on the "MessageBox=" settings
passed through the argument vector (equivalent to
UiShowMessageBoxesInSection() ).
- Use string-safe functions where needed (copy/concatenation/printf on
fixed-size buffers).
- Initialize BootPath and BootOptions buffers when fallback behaviour is not taken.
- Correctly skip all the understood whitespace (space & tabs) and the
quotes before reading the boot options when using the alternative syntax:
[Operating Systems]
section_name = "ReactOS" /bootoptions
Fixes the minor regression introduced in 370e8564 (r43875).
Fixes GCC 8 warnings like:
boot/freeldr/freeldr/disk/scsiport.c:806:31: error: 'partition(0)' directive writing 12 bytes into a region of size between 1 and 64 [-Werror=format-overflow=]

* [FREELDR] Abstract VGA BIOS specific code
WinLdrSetupSpecialDataPointers() uses INT 10h video interrupts, but they are not available on Xbox, so make them machine-specific.

* [FREELDR] Abstract getting extended BIOS data area
WinLdrSetupSpecialDataPointers() uses INT 15h AH=C1h to get extended BIOS data area, but it's not available on Xbox, so make it machine-specific.

- This allows getting the /NOGUIBOOT mode working correctly, as the latter
expects text-mode. Then, usetup (via BLUE driver) will change to a
different text-mode, or, GUI boot will change (via BOOTVID) to VGA
640*480 16-color.
- Always hide the VGA cursor.
- Remove also the deprecated boolean "Setup" in the *PrepareForReactOS()
functions.

- Introduce the AddReactOSArcDiskInfo() helper to get rid of the
duplicated reactos_arc_disk_info usage scattered amongst different
files.
- GetHarddiskInformation(): If we cannot read the disk that has been
enumerated by the BIOS, return a default identifier string.
- GetHarddiskInformation(): The last character of the disk identifier
string corresponds to whether its MBR is "valid"/has the 0xAA55
signature (use 'A') or whether it's not (use 'X'). Tested on Windows.
- Split PcInitializeBootDevices() in two: the first part of this
function that enumerates hard disks from the BIOS is now moved into
EnumerateHarddisks().
- The 'ValidPartitionTable' field of the ARC disk signature records must
be initialized with correct value that is specified in the different
AddReactOSArcDiskInfo() calls.
We now run the 1st-stage setup with a regular system hive, similarly to
what's done for the LiveCD, or for a regular ROS installation.
The ExpInTextModeSetup hacks I previously removed are now completely unneeded.

Split the "main" winldr.h header into the one containing global code
that actually doesn't really depend on the "windows" NT loader part,
and one that actually concerns code just for the NT Loader.
The latter goes into "ntldr".

Volume boot record is also implemented, it supports reading BTRFS tree structures with upto 64k node size.
This support required to change all path in Free Loader to lowercase for better performance.

This happened for the livecd, where the cdfs driver was inserted twice - once since it is the driver for the boot device, and the 2nd time, because it was specified in the registry - which was then initialized twice by the kernel, leading to a name conflict when trying to create another device object, which resulted in the newly created device object to be dereferenced again and the driver unloaded. This can be seen from the debug message "(ntoskrnl\mm\ARM3\sysldr.c:955) Leaking driver: cdfs.sys"
