94ec62e081 windows: add SetNamedPipeHandleState 
I added GetNamedPipeHandleState before but forgot the setter function,

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.

afaa3650a9 windows: do not write LastStatus parameter of TEB when converting errors 
The prior function updated the TEB's LastStatus member, which is not
what we want to be doing here. It's also not consistent with Microsoft's
own Go code for their pipe library, which properly uses the "NoTeb"
variant like this commit.

For good measure, we add a simple test case to make sure these paths are
being exercised.

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.

and related constants:

https://docs.microsoft.com/en-us/windows/win32/services/subscribeservicechangenotifications

Since these functions are only available on Windows 8+, and Go supports
Windows 7+, we mark them with "?" so that the caller can handle graceful
degradation.

111129e158 windows: correct CertOpenStore to expect a 0 return value on failure 
According to [1], this function returns NULL when it errors, rather than
INVALID_HANDLE_VALUE, which other Win32 functions return. Quick reversing
indicates that [1] is correct, as there's a `xor eax, eax` in the error
paths of the function just before jumping to the epilogue.

280f808b4a windows/svc: add IsWindowsService function 
CL 244958 includes isWindowsService function that determines if a
process is running as a service. The code of the function is based on
public .Net implementation.

IsAnInteractiveSession function implements similar functionality, but
is based on an old Stackoverflow post., which is not as authoritative
as code written by Microsoft for their official product.

This change copies CL 244958 isWindowsService function into svc package
and makes it public. The intention is that future users will prefer 
IsWindowsService to IsAnInteractiveSession.

Also this change adds "Deprecated" comment to IsAnInteractiveSession to
point future users to IsWindowsService.

Call to IsAnInteractiveSession is also replaced with IsWindowsService
in golang.org/x/sys/windows/svc/example package.

af0d71d358 windows: fix recvfrom and sendto data types 
Fixes wrong data type used in Windows recvfrom and sendto calls

In Windows, `int` refers to a 32-bit signed integer
(https://docs.microsoft.com/en-us/windows/win32/winprog/windows-data-types#int).
However, the current implementation (https://golang.org/cl/208321)
uses the `int` type, which can have a different size. This is especially
important when recvfrom` returns a 32bit value of `-1`, indicating an error,
since it is interpreted as the 64bit value 4294967295.
