This adds an evil hack to persuade libstdc++, which tries to import __acrt_iob_func from a DLL.
This can only be solved cleanly by adding a GCC-compatible C++ standard library to our tree later.
This fixes the crashes in HvpGetCellMapped on Windows Server 2003 when booting from Freeloader, as mentioned in maharmstone/btrfs#16.
When the bootloader loads the system hive, it cleans the data pertaining to any volatile keys. The Windows bootloader does this by setting SubKeyCounts[Volatile] to 0. After boot, the kernel marks any cell where this is 0 but SubKeyLists[Volatile] isn't HCELL_NIL as dirty, meaning that the sanitized version will then get flushed to the disk.
Because Freeloader sets SubKeyLists[Volatile] to HCELL_NIL straightaway, Windows thinks the cell is clean, and can unload it without flushing. If it then reads it from the disk, it will crash in HvpGetCellMapped due to the stale volatile pointers.
If you break on nt!CmpInitializeSystemHive on Windows and "gu" to the let the function run, you'll see that DirtyVector of the HHIVE has only the first 8 bits set. If you run it using the official bootloader, it'll have a lot more than that.
- kernel32!BaseCreateStack() is compatible with ntdll!RtlpCreateUserStack().
- When checking whether a stack guard page can be added, its size has to
be accounted for in the checking logic.
- We have to satisfy the PEB::MinimumStackCommit constraint.
- We cannot use PEB::GuaranteedStackBytes in BaseCreateStack() since it is
nowhere initialized (default is 0). It gets initialized to a non-zero
value when the user manually calls SetThreadStackGuarantee().

- RtlpCreateUserStack(): Fix memory leak in failure case.
- RtlpFreeUserStack() doesn't need to return anything.

These are required by latest mingw-w64 stl and we are mixing this with our crt headers.
Define _CRT_NO_POSIX_ERROR_CODES in all modules that define their own constants.
hid.dll and hidparse.sys must understand the same HID preparsed data,
so use the same code in hid.dll and in hidparse.sys
At the same time, this permis implementation of some HidP_* functions.
Interface between both is not anymore the HidParser_* functions, but
the HidP_* functions and the AllocFunction/FreeFunction/DebugFunctions/
ZeroFunction/CopyFunction.
- Modify atldef.h for non-ReactOS environments.
- Update ATL testcase project files (from v120_xp to v140_xp).
- #define HAVE_APITEST and use it.
- s/NULL/0/
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.
This fixes the following compiler errors:

MSVC was previously given a "result" variable to copy the fscale result from st(0). This led to another "fld" FPU stack push at the very end without popping the source value from the FPU stack.
Moreover, this copy isn't even needed: A simple "fstp st(1)" at the end pops an element from the FPU stack while effectively storing the result in st(0), the register used for returning a double value.
This problem didn't affect GCC, as it is only given the "fscale" instruction and does all necessary stack operations itself.
However, looking into the CRT sources, I found many other i386 implementations with inline assembly suffering from the same problem.
Fortunately, they have been replaced by pure assembly implementations a while ago, so it's time to finally remove them.
ldexp would have also been a candidate for a pure assembly implementation, but the required check for NaN and setting errno (verified on Win2003) already outweighs the benefits.
And we cannot just do a NaN check with FUCOMI as this is an i686/pentiumpro instruction while we're still targeting i586/pentium.
I'm also using this opportunity to clean up the ldexp.c header and only put in the remaining contributors as returned by "git blame".
