ea436ef09d windows: add iphlpapi routing functions 
NotifyRouteChange2 registers to be notified for changes to IP route
entries. Call GetIpForwardEntry2 on received row to retrieve complete
information.

GetIpForwardTable2 retrieves the full routing table.
FreeMibTable frees the buffer allocated by the functions that return
tables of network interfaces, addresses, and routes.

899c23279d windows/mkwinsyscall: use syscall.SyscallN instead of syscall.Syscall{6,9,12,15} 
Replace syscall.Syscall6, Syscall9, Syscall12, and Syscall15 with
syscall.SyscallN for Go 1.18+. This simplifies system calls by allowing
the exact number of arguments needed, eliminating zero padding and
reducing potential errors.

Updated TestSyscallXGeneration to TestSyscallNGeneration to verify
correct SyscallN generation for different argument counts.

6a85559a3f windows: fix dangling pointers in (*SECURITY_DESCRIPTOR).ToAbsolute 
Prior to this CL, a byte slice was allocated via make to use as the
absoluteSD argument passed to the Windows API MakeAbsoluteSD.

MakeAbsoluteSD then sets pointers outside the view of the GC, including
pointers within absoluteSD that point to other chunks of memory
we pass into MakeAbsoluteSD.

CL 653856 recently allowed more make results to be stack allocated,
which worsened the problems here and made it easier for those
pointers in absoluteSD to become dangling pointers, though the
core problems here existed before.

This CL instead allocates absoluteSD as a proper SECURITY_DESCRIPTOR
struct so that the GC can be aware of its pointers. We also verify the
pointers are as we expect, and then set them explicitly
in view of the GC.

Updates golang/go#73199

1b2bd6bb49 windows: replace all StringToUTF16 calls with UTF16FromString 
`StringToUTF16` is deprecated and will panic if given an "invalid"
string (in particular, one that has a null byte in it).  The replacement
function is `UTF16FromString`, and it returns an error if there was
a problem.

This change replaces all uses of `StringToUTF16` with `UTF16FromString`.
The `service` struct now no longer stores a `string` name but rather
a `*uint16` pointer to the name.

It should not be possible to panic due to UTF16 string conversion
at this point.

Fixes golang/go#73006

29298aaa6a windows: delete TestGetKeyboardLayout 
According to
https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getforegroundwindow
GetForegroundWindow can return nil in some circumstances. So
GetForegroundWindow cannot be used in the TestGetKeyboardLayout.
Just delete the test for now.

Fixes golang/go#68671

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.

cabba82f75 windows: use uint32 for serial comm flags for consistency 
This is a follow-up to https://go-review.googlesource.com/c/sys/+/572295
and specifically the comment
https://go-review.googlesource.com/c/sys/+/572295/comment/a00e1a2e_e3b01666/.

All other structs and methods us uint32 in golang.org/x/sys/windows
for flag bitmasks, so make the serial communication structs use uint32
to be consistent with the rest of the package.

As a side effect the DTR_CONTROL_* and RTS_CONTROL_* constants are
updated to reflect the positions of the bits in the 32-bit flags.

This change adds the remaining functions described in "Serial
Communications in Win32", enabling Go applications and libraries to be

Windows.

x/sys/unix already has equivalent functionality through termios.
