The SECURITY_ATTRIBUTES struct always takes a SECURITY_DESCRIPTOR
pointer. Now that we've defined SECURITY_DESCRIPTOR, make
SECURITY_ATTRIBUTES properly specify the type. This eliminates the need
for terrible uintptr(unsafe.Pointer(...)) casts everywhere.

This adds the basic foundation for dealing with security descriptors and
access control lists. The basic creators and getters are included in
this patch. These are some of the most fundamental security objects on NT,
and any work with the security API is fairly limited without it. These
are "core" NT structures.

There are a few functions to control the behavior of shutdown and
logout, both for what the current process does during shutdown, and also
whether or not the current process is running in an interactive session.
The below code is a port of the MSDN example code to Go using one of the
added new functions:
https://docs.microsoft.com/en-us/windows/win32/shutdown/how-to-shut-down-the-system
func shutdownLikeMSDNDoes() error {
seShutdownName, err := windows.UTF16PtrFromString("SeShutdownPrivilege")
if err != nil {
return err
}
var shutdownPriv windows.Tokenprivileges
err = windows.LookupPrivilegeValue(nil, seShutdownName, &shutdownPriv.Privileges[0].Luid)
if err != nil {
return err
}
shutdownPriv.Privileges[0].Attributes = windows.SE_PRIVILEGE_ENABLED
shutdownPriv.PrivilegeCount = 1
process, err := windows.GetCurrentProcess()
if err != nil {
return err
}
var token windows.Token
err = windows.OpenProcessToken(process, windows.TOKEN_ADJUST_PRIVILEGES | windows.TOKEN_QUERY, &token)
if err != nil {
return err
}
defer token.Close()
err = windows.AdjustTokenPrivileges(token, false, &shutdownPriv, 0, nil, nil)
if err != nil {
return err
}
err = windows.ExitWindowsEx(windows.EWX_SHUTDOWN | windows.EWX_FORCE,
windows.SHTDN_REASON_MAJOR_OPERATINGSYSTEM | windows.SHTDN_REASON_MINOR_UPGRADE | windows.SHTDN_REASON_FLAG_PLANNED)
if err != nil {
return err
}
return nil
}
Note, though, that this function doesn't set the token privs back to how
they were before, which isn't good. A more robust method than the MSDN
one above would be to duplicate&impersonate.

Indeed Go has mutexes of its own, but these are considerably
different from the native Windows ones, that can work across processes
and be put in various namespaces. They're an essential part of Windows
systems programming and important for interfacing with various external
interfaces.

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.

I realize that at this time, x/sys/windows is most certainly not aiming
to be some sort of UI library or anything remotely close to that.
However, MessageBox is sort of the one universal Windows API that's used
even for console programs. It's *the* classic debugging helper. It's
even pretty customary for console programs to display their usage
message in a message box rather than stdout. I realize this might be
somewhat disturbing to consider if you're in the blissful Unix utopia,
but on Windows, this is just sort of how things roll. Easy access to
MessageBox() is important.

While the types_windows file previously had a small handful of types,
this forced application code to have an awkward mixture of artisanal
error constants and factory-ready ones. This commit adds the missing
ones and separates them into a new file, since they are quite numerous.
These also preserve the order of winerr.h, which should make it somewhat
easier to import new ones in the future.

The previous selection was a bit haphazard, and defining random
constants in an application and combining those with existing constants
in this library looks kind of weird. So instead let's add the actual set
of flags, instead of the strange prior assortment.

This CL is a copy of CL 106275 (see CL 106275 for details).
It introduces CertInfo, CertTrustListInfo and CertRevocationCrlInfo
types. It uses pointers to new types instead of uintptr in CertContext,
CertSimpleChain and CertRevocationInfo.
CertRevocationInfo, CertChainPolicyPara and CertChainPolicyStatus types
have uintptr field that can be pointer to many different things
(according to Windows API). So this CL introduces Pointer type to be
used for those cases.
