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.

This is the way to do things like execute a process elevated with UAC
and interact with that whole system. It turns out to be quite important
for writing Windows software.

These allow actual inspection of SIDs. For example, it might be
desirable to iterate through the group SIDs in order to find one set by
SERVICE_CONFIG_SERVICE_SID_INFO:
for _, g := range groups {
if g.Attributes != windows.SE_GROUP_ENABLED|windows.SE_GROUP_ENABLED_BY_DEFAULT|windows.SE_GROUP_OWNER {
continue
}
if !g.Sid.IsValid() {
continue
}
if g.Sid.IdentifierAuthority() != windows.SECURITY_NT_AUTHORITY {
continue
}
if g.Sid.SubAuthorityCount() < 6 || g.Sid.SubAuthority(0) != 80 {
continue
}
sid = g.Sid
break
}
Another usage of the APIs added would be to find if a user is in the
administrator group with either an elevated or unelevated token:
isAdmin := false
for _, g := range groups {
if g.Attributes&(windows.SE_GROUP_ENABLED|windows.SE_GROUP_USE_FOR_DENY_ONLY) == 0 {
continue
}
if !g.Sid.IsWellKnown(windows.WinBuiltinAdministratorsSid) {
continue
}
isAdmin = true
break
}

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 svc package exposes svc.SessionChange, but it's impossible to do
anything with them without these structures, and without being able to
enumerate them prior to events, the events themselves aren't useful, so
we add the enumeration functions as well.

This lays the groundwork for service notification and tracking by adding

or later if we're feeling ambitious, we can see if we can come up with a
generalized solution in x/windows/svc.

These are extremely useful functions and core to the Windows security
API. They are so useful, in fact, that most of these were taken right
out of the Go repo's internal/syscall/windows package.

We already have all the structs and constants for async I/O, and the
various functions of x/sys/windows take the right parameters. But we're
missing the final step of any ordinary async I/O routine: getting the
result of overlapped I/O. Without this, the rest of the plumbing
supported by this module isn't actually so useful. So add this small
oversight.

The %WINDIR% variable is an odd choice and not even entirely reliable.
Since Windows 2000, there has been a specific function for determining
this information, so let's use it. It's also a useful function in its
own right for folks who want to launch system tools in a somewhat safe
way, like netsh.exe.

GetConsoleScreenBufferInfo is also changed by re-running 'go generate'
to pass a pointer to ConsoleScreenBufferInfo (instead of a pointer to
pointer).

If we want new secure DLL approach to be adopted, we should make
conversion as simple as possible to explain and implement.
I think that replacing
syscall.NewLazyDLL(...) -> windows.NewLazySystemDLL(...)
is easier than
syscall.NewLazyDLL(...) -> &windows.LazyDLL{Name: ..., System: true}
So I propose we introduce convenience function NewLazySystemDLL.
