[SDK] Don't assert on big keys in bootloader

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.
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.
They are correct and are more performant.
- Rewrite WinLdrAddDriverToList() on the model of CmpAddDriverToList()
with support for CmpIsDriverInList().
- Disable RegEnumKey() as it is now unused.
This allows: (i) to shorten dramatically the lengths of the static
registry path strings being used (and thus, allow for reduced binary
file size), and (ii) to prepare future support for selecting different
control sets (and related Last-Known-Good configurations).
- Use UNICODE_STRINGs wherever possible.
- Retrieve the OEMHAL font file name. TODO: Load it!
- In WinLdrLoadNLSData(), don't open/close each file twice (and showing
we are loading them twice). Instead, open all files at once (and keep
them that way), retrieve their sizes and do the calculations, then
load their respective contents one by one -- giving loading feedback
only at that point -- and finally close all of them at once.
- Move boot options parsing early on in LoadWindowsCore().
- Add WinLdrIsPaeSupported(), move in it the PAE options parsing.
The aim is to perform other tests to determine whether or not to
enable PAE, and select an adequate kernel image.

- Fix parsing of the NOEXECUTE options, taking their precedence
into account. Most of these are also x86-specific.
A Kernel Debugger Transport DLL is always loaded for Windows XP+ :
either the standard KDCOM.DLL (by default), or an alternative
user-provided one via the /DEBUGPORT= option. If this alternative
does not exist or fails to be loaded, fall back to the standard
KDCOM.DLL.
If no KD dll is loaded, kernel loading would fail because of the
resulting unsatisfied KDCOM dll import (tested on Windows and ReactOS).
+ Normalize kernel, HAL and KD dll file names to lowercase (needed for
case-sensitive installations).

- Reset the UI to a minimal one in SOS mode.
- In SOS mode, a trace of loaded files is displayed on the screen,
instead of the usual progress bar.
- Add a callback to the PE loader to notify when imported DLLs are
loaded for a main image. This allows getting an accurate SOS trace.
- Remove excessive UiDrawBackdrop() calls that caused too many
unnecessary redraws.
- ProgressBar: Clear only the portions that need to be cleared up.
This allows to not use DrawBackdrop anymore and the flickering.
Actually, RegCloseKey() is here a dummy macro that just "returns"
success. Indeed, the internal implementation of RegOpenKey() doesn't
really allocate internal structures: it just returns a "pointer" to
already existing allocated data. Therefore nothing needs to be closed/freed
later on.
- Move a few lines around.
- Switch to RtlZeroMemory() from memset().
- Make while() more explicit.
For CORE-12802:
- Add/Fix FrLdrHeapAlloc() failure handling and related.
Especially, add/fix FrLdrHeapFree() calls.
- Add/Improve ERR() to some FrLdrHeapAlloc() failure cases.

at runtime from the boot selection menu or from FREELDR.INI.

For a proper override of the options by new user options, specify the
/SIFOPTIONSOVERRIDE switch in addition. Otherwise, user options are
merged with those retrieved from TXTSETUP.SIF, with priority given to
the former ones.
- Update the documentation for the 'ReactOSSetup' OS type in the
FREELDR.INI file template.
- Use a different prompt in the custom boot options editor for the
'ReactOSSetup' OS type, with adequate explanation.
- Get rid of the ReactOS-specific TXTSETUP.SIF 'DbgOsLoadOptions' value,
and use instead the Windows-compatible 'SetupDebugOptions' value that
is added to the other load options when debugging is to be enabled.
- Introduce a set of NtLdrGet(Next)Option(Ex) helpers that allow
retrieving respectively, the "next" option in an options string,
and retrieving a given named option in such an options string,
by correctly parsing that string.
Valid syntaxes:
/OPTION1 /OPTION2/OPTION3 OPTION4 /OPTION5(=...) ...
Options separators are slashes, or whitespace (space, tab), mandatory
if no slash is used, and otherwise optional.
- Use these functions wherever NT load options are being parsed.
- Simplify the parsing of /DEBUGPORT=... using these functions.
- When parsing the /HAL=... or /KERNEL=... options, only the first
encountered one is taken into account, any other ones are discarded.
- When parsing the other load options, only their first occurrences are
taken into account, any other repetitions are discarded.
* The NOPAE option overrides any previous PAE option.
* Any NOEXECUTE(=) option should override any previous
NOEXECUTE=ALWAYSOFF (or equivalently, EXECUTE) option.
This parameter is not needed since it's possible to determine, from
within this function, whether or not we are in Setup mode, by just
looking for the presence of a non NULL LoaderBlock->SetupLdrBlock.
According to PC-9801 Bible p. 50, divisor for PIT will become unsupported in some cases after having removed the fractional part. Replace 19200 value with 9600 which is supported by both 10 MHz and 8 MHz machines.
Triggered by a fix attempt by M.Harmstone in PR #1905.
- Introduce #defines and helper functions so as to initialize the
descriptors in a human-readable and tractable way, without magic values.
- Rework some comments.
- Document what the changes are in (Longhorn and) Vista+.
Data has been obtained through using the WinDbg command: dg 0x00 0xFF
(for example), that lists all the selectors from 0x00 to 0xFF included.
See https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/dg--display-selector-
for more details.
- Implement support for the "RDIMAGELENGTH" and "RDIMAGEOFFSET" boot
options. Fixes CORE-15432.
- Separate the initialization of the global gInitRamDiskBase /
gInitRamDiskSize variables from the FreeLdr command-line, and the
actual initialization of the internal variables of the RamDisk.
The latter are initialized via calls to RamDiskInitialize().
- Implement 'SeekRelative' mode in RamDiskSeek().
- Make RamDiskLoadVirtualFile() internal function that gets called by
RamDiskInitialize(), and we use the latter in the NT loader instead.
On Windows <= 2003 (and current ReactOS), this is the "InfName" value
in the "HKEY_LOCAL_MACHINE\CurrentControlSet\Control\BiosInfo\" key.
(The default file name found there is 'biosinfo.inf'.)
On Vista+, this is the "InfName" value in the
"HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Errata\" key.
(The default file name found there is 'errata.inf'.)
For 1st-stage setup, the file is specified in the "InfName" value of
the "BiosInfo" section in the TXTSETUP.SIF file.
