* [HALXBOX] Formatting only.
* [HALXBOX] Don't use Xbox partitions if MBR signature found.
- Fixes BSOD 0x7B when booting from a HDD that have both MBR and BRFR signatures.
- It happens when you format Xbox (BRFR) disk as MBR.
After that "BRFR" signature is still located at sector 3.
- Also fix pre-existing leaks.

(Regression introduced by commit 2e1b82cf, r44841.)
In some cases the number of valid (!= 0xFFFF) entries in the IOPM can be
larger than the assumed size (32) of the entries cache. The maximum
possible number of entries is equal to IOPM_SIZE / sizeof(USHORT).
A way to reproduce the problem is as follows: start ReactOS in debugging
mode using '/DEBUG /DEBUGPORT=SCREEN' . Then manage to break into the
debugger exactly during the execution of Ke386CallBios() triggered by
display initialization (for example in my case, while a video driver was
being initialized via the HwInitialize() call done by videoport inside
IntVideoPortDispatchOpen() ).
When this happens, a "concurrent" execution between Ke386CallBios() and
the HAL function HalpStoreAndClearIopm() takes place. This is due to the
fact that when entering the debugger in SCREEN mode, the following
call-chain holds:
InbvResetDisplay() -> VidResetDisplay() -> HalResetDisplay() ->
HalpBiosDisplayReset() -> HalpSetupRealModeIoPermissionsAndTask() ->
HalpStoreAndClearIopm().
However, the code of Ke386CallBios() has reset the IOPM contents with
all zeroes instead of 0xFFFF, and this triggers the caching of all the
entries of the IOPM by HalpStoreAndClearIopm(), whose number is greater
than the wrongly assumed number of '32'.
As Thomas explained to me, "Windows supports [the maximum number of IOPM entries],
it just makes a full copy of the table instead of this indexed partial copy."
And I agree that this overengineered so-called "optimization" committed
in 2e1b82cf contributed in introducing an unnecessary bug and making the
code less clear. Also it makes the IOPM cache larger than the necessary
size by twice as much. Finally, Ke386CallBios() also caches IOPM entries
before doing a 16-bit call, and obviously uses the more straightforward
way of doing a direct copy of the IOPM table (using RtlCopyMemory()).
I wonder what kind of "optimization" this tried to achieve, knowing that
we are not doing like thousands of 32->16bit BIOS interrupt calls per second
in ReactOS...

- Don't match device id outside current vendor id list.
- Don't match subsystem id outside current device id list.
- Refactor some magic constants.
Addendum to 894635b.
- Match subclass properly, don't match third subclass.
- Don't match subclass from next class, add ClassEnd boundary.
- Use class name if subclass name not available.
- Gracefully return "Unknown" if no class name found.
This fixes the bug when VidInitialize asks for different translated addresses
and VgaIsPresent always returns FALSE either because the machine does not have
VGA controller at all (e.g. 86Duino Zero), or it does have video hardware
that is not compatible with VGA standard (e.g. Original Xbox).
The problem investigated by Stanislav Motylkov. Suggested fix by Thomas Faber.

There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr

Because we can encounter pending interrupts repeatedly,
HalpEndSoftwareInterrupt and HalEndSystemInterrupt already clean up the stack
space for their arguments (done for CORE-11123/CORE-14076).
However these functions are called from C functions such as KiInterruptDispatch
and HalpDispatchInterrupt2[ndEntry]. These callers also use up stack space,
and it is unknown how much.
To fix this, we simply reset the stack pointer to the location of the trap
frame, which is where it points during a first-level dispatch. This cleans
up the stack usage of any callers higher up, and is okay because a return
will happen through the trap frame anyway.
Dedicated to Pierre.
