- Split buffers on page to prevent non-contiguous memory being passed to driver.
- Protect CIrpQueue::GetMappingWithTag, ReleaseMappingWithTag with spinlock to prevent race conditions
(GetMapping, ReleaseMapping do not need spinlock, they are only called from a service routine).
- Remove ASSERT in CIrpQueue::ReleaseMappingWithTag, when mappings are released out of order. Just ignore
the tag argument and release the next one in the list. This is what windows does, confirmed by calling
PortWavePciStream::ReleaseMapping() with tag argument set to 0, absolutly no difference observed.
Allowing out of order release is essential given that a driver is not permitted to hold a spinlock when calling
ReleaseMapping().
- Remove IIrpQueue::HasLastMappingFailed(), it never worked and there is no way it could work.
CPortPinWavePci::HandleKsStream() call MappingAvailable() non-conditionally, this is what Windows does,
verified by debug prints in ac97 driver.
- Implement CIrpQueue::NumData().
- Remove incorrect interlocked operations/volatile variables and several (now unused) class fields.
- Call UserDereferenceObject function in UserCreateInputContext.
- Don't call UserDereferenceObject against input context at the other places.

- Don't store trailing newlines in the exception description text strings.
- Remove unused i386PrintChar().
- Display CR4 in x86.
- Use the "indentation" printf generation trick in order to get aligned
strings for (CF4 and) DR6 and DR7, without having to hardcode the tons
of alignment whitespaces (--> make the strings stored in freeldr shorter).
- Show the IP/ErrorCode/EFlags/GDTR/IDTR/LDTR values vertically aligned.
- Display the stack frames in both x86 and x64 modes.
- Adjust the instruction pointer when a BREAKPOINT or OVERFLOW exception
arises, so that the offending instruction can show up in the instruction
stream.
CORE-16748
- Display the correct TR register value.
- Ensure that the x86 segment register values displayed are really
2-byte long.
Segment registers are intrinsically 16 bits. Even if the x86
KTRAP_FRAME structure stores them as ULONG, only their lower 16 bits
are initialized. We thus cast them to USHORT before display.
These segment registers are saved in a stack-based KTRAP_FRAME by the
CPU trap mechanism (for SS), and by 'push CS' etc. instructions for
the others, and from Intel documentation, we know that:
"
If the source operand is a segment register (16 bits) and the operand
size is 64-bits, a zero-extended value is pushed on the stack; if the
operand size is 32-bits, either a zero-extended value is pushed on the
stack or the segment selector is written on the stack using a 16-bit
move. For the last case, all recent Core and Atom processors perform
a 16-bit move, leaving the upper portion of the stack location unmodified.
"
So it may happen, when using the push, that either they get zero-extended,
or garbage gets stored in the higher bits, and these need to be trimmed.
Note that even if the MS PSDK and MSDN documents an hypothetical
ANSI version SHCreateFileExtractIconA(), this one never existed
exported in any Windows version!

Makes testing easier on real hardware (especially for these configs
where debugging can only be done via screen mode).
Add also an experimental Setup ACPI APIC entry in bootcd.ini for testing
purposes, along the lines of commit 5ee09256d .
In the similar LiveCD entry, use instead the /HAL= option.

Set the API_BITMAP flag for bitmaps created by EngCreateBitmap().
This avoids failure when created bitmap is passed to NtGdiSelectBitmap(), since it checks for this flag and fails if it isn't set.
Otherwise, if failure occurs, the bitmap is hot handled properly.
Setting this flag outside of that function is not an option at all, because it is a public (exported) function, and in many cases it's called directly by the caller (in case with MS DDraw stack, it can be called also by dxg.sys from dxgthk!EngCreateBitmap, which directly calls win32k!EngCreateBitmap).
In particular, it allows Windows XP/2003 DirectDraw stack (ddraw.dll & dxg.sys) to properly work in ReactOS (in software emulation mode), even on real hardware. So now, a lot of DirectX 1-7 apps and games (whose can work withoug hardware acceleation), are working properly with ddraw.dll + dxg.sys replacement! Also Justin Miller (DarkFire01) confirmed that even Direct3D software emulation now also works correctly on real hardware!
