Due to some kind of mixup, I thought the series for log(x) was actually for log10(x).
Fix Fast486FpuCalculateLogBase2 by dividing the result with log(2) and not log10(2).

Fix a copy-paste bug. Adjust the number when subtracting in Fast486FpuAdd. Don't overflow
the mantissa in Fast486FpuToSingle/Fast486FpuToDouble without correcting the exponent.

INI files for setting parameters? Lets get to the past Win 3.11 standards and make a configure dialog for that which reads and writes the stuff to the registry.

Followup to r67830: When no one handles a message, properly return that it was not handled.
This way all messages are handled correctly and not just NCCREATE.
Also took the chance to short-cut NCDESTROY, since the icon handlers have no need to receive this message.
CORE-9592 #resolve
svn path=/trunk/; revision=67831
do not handle WM_NCCREATE in ProcessWindowMessage
otherwise it get passed to ProcessIconMessage which will flag it as handled in case g_NumIcons is 0
which then will result in ATL not calling DefWndProc anymore

Fix Fast486FpuArithmeticOperation. It doesn't really matter for the operation
itself which operand is the source/destination, because the FPU actually
always performs the operation on ST0 and something else. So, FDIV/FDIVR were
never really reversed here, it's just that FDIV always divides ST0 by something
and FDIVR always divides something by ST0.

Fix UnsignedDivMod128 (again).
Fix Fast486FpuAdd to handle numbers whose difference of exponents is greater than
the number of bits in the mantissa.

The maximum length of hardware profiles names is 79 characters. Use a matching string length and set the length of the edit control accordingly.

Implement support for FastIO for:
- FastIoQueryBasicInfo
- FastIoQueryStandardInfo
Now, with this commit and the two previous, ReactOS won't attempt to issue an IRP for these query, but will directly go with the FastIO path.
The performance improvement is really visible in 1st stage (at least, here with VBox).

Fix several division related problems:
- In UnsignedDivMod128, fix the leading zero calculation for 128-bit numbers.
- In Fast486FpuDivide, there's no need to increase the exponent by 64 (adding zeros
at the end of a number after the decimal point changes nothing).
- FDIV/FDIVR were reversed
svn path=/trunk/; revision=67820
- Zero is not a denormalized number.
- In Fast486FpuMultiply, we must account for the fact that the resulting mantissa
also has the "decimal point" at the second position.

Implement MiGetFileObjectForSectionAddress and use it in MmGetFileNameForAddress and NtAreMappedFilesTheSame. Don't call MmLocateMemoryAreaByAddress from these functions anymore.

Fix a fixme in VfatGetUserBuffer():
Only request high priority page when in the paging path. Otherwise, request normal priority
