On macOS, the SysctlKinfoProcSlice() function may be used to fetch the contents of the process table. As the process table may grow between the first and second call to sysctl(), the second call may fail with ENOMEM. In that case we simply need to retry.

On Linux, the last argument of pselect6 system call is **not** a
sigseg_t * pointer, but instead it is a structure of the form:
struct {
const sigset_t *ss; /* Pointer to signal set */
size_t ss_len; /* Size (in bytes) of object pointed
};
See man 2 pselect6.

On OpenBSD-current, clang emits a warning message to standard output for the use of strcpy, e.g.:
_errors.c(/tmp/_errors-673190.o:(main)): warning: strcpy() is almost always misused, please use strlcpy()
This message makes it into the Go source being created, causing gofmt to error on the invalid syntax, and leaving the zerrors file empty.
Using strlcpy would be preferred here, but strncpy is enough to silence this message, and is more portable.

Implementation generated directly with mkwinsyscall has a wrong
assumption about the expected value for PIDs buffer size.
This change adds some small manual code that converts the input
slice length to the number of bytes of the array backing the slice.
A test is also added. It fails with the previous implementation.

Notably, the DisplayName field was set to the same thing in both
sys.TestExample and mrg.TestMyService, which may explain the collision
reported in golang/go#59298.
Moreover, the adjective ”my” conveys no information whatsoever — we
shouldn't use it in tests or examples.
Also skip the tests that install services if GO_BUILDER_NAME is not
set, to reduce the likelihood of 'go test all' in a user's working
directory being mistaken for a malicious or compromised program.

The existing uintptr arithmetic is arguably valid because the
environment block is not located within the Go heap
(see golang/go#58625).
However, unsafe.Add (added in Go 1.17) expresses the same logic with
fewer conversions, and in addition avoids triggering the unsafeptr
vet check.

Instead of defining a dedicated type goIovec with the correct *byte type
for its Base field like CL 412496 did, modify the Base field of the
original type Iovec (generated from struct iovec) in mkpost.go. This is
akin to how we already change []int8 to []byte for several other types.

mkpost.go is platform independent and can in principle be run on a GOOS
other than the one we're generating the syscall wrappers for. Allow
overriding GOOS by setting GOOS_TARGET, similar to other generator
programs in the repo. This e.g. allows testing mkpost.go changes on a
different GOOS.

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.

The setattrlist() function can be used to mutate the attributes of files through a single call. For example, one can perform a chmod(), chown(), chflags(), [...] all at once.
This change also adds bindings for the UF_* and SF_* flags that are accepted by chflags(). This makes it possible to use setattrlist() to perform the equivalent of lchflags(), for which we currently have no binding.

On Solaris, AIX, and zOS, the req argument of ioctl() is a signed int,
not an unsigned long like on other platforms, which means many constants
are negative, causing friction when passing them to a uint argument.
Correct the signature of these functions to pass the req argument as
signed, just like libc.
