While RtlGetVersion was added so that users can get the Windows version
that isn't affected by manifesting, RtlGetVersion is still stubbed out
by the application compatibility layer (aclayers.dll and apphelp.dll)
for certain processes, such as msiexec.exe, rendering these functions
useless for actually determining the underlying operating system. This
matters in the case of msiexec.exe using a custom action DLL to install
a kernel driver, which of course is version specific. This is also
useful, it turns out, for the C runtime library, in which Microsoft uses
this function too. It's existed as a stable interface since Windows XP,
has Wine support, and is used in a decent amount of software.

Other functions, like GetVersion(), will lie about the OS version
depending on various win32 and manifest compatibility shims in place.
Calling RtlGetVersion is the proper way to retrieve the true OS version.

This adds the recommended API for determining well-known folder paths,
such as where to place application configuration data. The MSDN
documentation mentions an optimization for the "current user" by passing
NULL as the token, so we provide both variants.

This corrects the Windows int type to be the more correct int32 Go
analog, as well as not using GetLastError() for the error value of the
GUID string parsing function.

Virtually every project that works with x/sys/window's GUIDs winds up
rolling their own version of this in one way or another. So let's add
the correct win32 wrappers for it, so that these are always generated,
parsed, and converted in the uniform correct way.

The GetCurrent*Token variety of functions are actually implemented as
inline functions in the header files of the SDK. Attempting to call out
to these as library functions is an error. This commit also adds a test
to ensure that these work as expected.

The security API is already quite extensive, but for some strange
reason, this essential and useful function was left out of the initial
port. So, we add it here, along with the relevant constants and a test
case.

syscall_windows_test.go:84: Fatal call has possible formatting directive %x
Fix it by using Fatalf instead.

Semi-automatic migration from package syscall to package {plan9,windows,unix}.
No builds attempted yet, but this gets a lot of noise behind us so subsequent
CLs will be more concise and easier to follow.
Subsequent CLs will have semantic content.

This CL copies to each package of go.sys the files from syscall it will need.
Different directories have different files, but these:
mkall.sh
str.go
syscall.go
mksyscall.pl
race.go
race0.go
syscall_test.go
are copied to all three.
No changes yet, these are just copies. They are not ready to use yet:
package names are wrong, for starters. But this clean copy will make
it easier to follow the changes as the packages are enabled.
