76700875df windows: add GetAce Windows API 
GetAce obtains a pointer to an access control entry (ACE) in an
discretionary access control list (DACL), which controls access to
an object.

Adds the ACE_HEADER and ACCESS_ALLOWED_ACE structs.
Adds GetEntriesFromACL function which returns an array of ACEs from the
given ACL if no errors have been encountered.

f34bb9fccc windows: add net user enum 
In the go windows package, you can get user information by using
`NetUserGetInfo` along with a specified level. However, there is
no way to get a list of the users.
The only options are to
1. know the users,
2. brute force users, or
3. use an external tool or command (`net users`).

I suggest adding a function that implements the windows api for
`NetUserEnum`. This will allow a built in way to enumerate
users and follow the standard.

A side note is that I used `buf **byte` because
it is how the others are done, but using `buf *byte`
works just as well.

This change adds the remaining functions described in "Serial

dbd8f99a5e windows: add Service.ListDependentServices 
This method allows a user to list all Windows services which are
dependent upon a given service.

This commit makes use of the EnumDependentServices Windows API call.
Without this, a user would have to iterate through each service on the
system, and check if the given service is listed in each service's
dependencies list.

The implementation of ListDependentServices is mostly the same as
Mgr.ListServices, as the API calls behave in the same way.

fe61309f88 windows: add SetupAPI and CfgMgr32 functions 
Simon and I have worked on these on and off for a number of projects
over the last 3 years and by now it's quite stable and mature. Rather
than carrying this around privately, these have now been updated to be
in the style of x/sys/windows, in this case matching how the
security_windows.go file does things. Specifically, because these APIs
are kind of hard to work with, and quite lengthy, we split them off into
a setupapi_windows.go file, just like security_windows.go.  We already
had the setupapierrors_windows.go file, so that's been folded into the
new one that contains the additional definitions nad functions.

These APIs are among the most obtuse to work with in all of Win32, so
considerable attention has been spent trying to make these wrappers both
quite "raw" so that they match the win32, but also accessible from Go.
The fact that they're so old in Windows history makes for a few tricky
things, like struct padding that doesn't quite match Go's rules, but
we've been able to accommodate basically everything after quite a bit of
work.

444254391f windows: treat proc thread attribute lists as unsafe.Pointers 
It turns out that the proc thread update function doesn't actually
allocate new memory for its arguments and instead just copies the
pointer values into the preallocated memory. Since we were allocating
that memory as []byte, the garbage collector didn't scan it for pointers
to Go allocations and freed them. We _could_ fix this by requiring that
all users of this use runtime.KeepAlive for everything they pass to the
update function, but that seems harder than necessary. Instead, we can
just do the allocation as []unsafe.Pointer, which means the GC can
operate as intended and not free these from beneath our feet. In order
to ensure this remains true, we also add a test for this.

Updates golang/go#44662.

134d130e1a windows: add support for NTSTATUS values 
The native NT API returns error values from a different namespace as the
usual Win32 one. This means it needs to be typed differently. This
commit adds broad support for using NTSTATUS values in a new type called
NTStatus.

First we add the type as a basic uint32. Then we add all of the
predefined constants from ntstatus.h, by augmenting mkerrors.bash to do
automatic extraction. There's a convenece way to convert an NT error to
a Win32 error, so we add the NTStatus.Errno() function. Since NTStatus
is an error type, we define an Error() function that returns a string by
asking ntdll.dll for its contents, in the exact same way that
syscall.Errno.Error() does, by calling FormatMessage. Since functions
need to actually use this, we add the rule that if a `//sys` declaration
returns an error value called "ntstatus", then the type underlying the
error interface is an NTStatus instead of an Errno. Finally we fix one
function that was returning an error interface of an Errno rather than
an NTStatus.
