ptracePtr was introduced in CL 469835 for darwin but it's not used on
this platform. Also, the argument types for addr and data were swapped
in the generated ptrace1Ptr (probably because the change was not
generated but done manually).
This change also includes generated changes moving some definitions in
zsyscall_darwin_*.go and removing some empty lines in
zsyscall_darwin_*.s. These changes result from running ./mkall on
darwin/amd64 and darwin/arm64.

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.

As of Go 1.21 syscall.Setrlimit and syscall.prlimit can affect
starting a new process, by restoring the original NOFILE rlimit.
That is recorded locally in the syscall package, so just always
call the syscall functions.

Direct syscalls are no longer supported on darwin (CL 250437), so
utimensat can be implemented as a wrapper around the libc function.
The utimensat function was added in macOS 10.13 and Go 1.17 dropped
support for macOS 10.12.
This also allows to drop the fallback to setattrlistTimes which was
used to set timestamps with nanosecond resolution before utimensat could
be used, see golang/go#22528 and CL 74952.

In Go 1.17 we will introduce a register-based ABI on some
platforms, as well as ABI wrappers to bridge the ABIs. For Darwin
syscall wrappers, it needs to be called directly, instead of
through wrappers. Currently, it is written as that the syscall
functions are defined in assembly and their addresses are taken
from Go using funcPC. In Go 1.17 this will result in the address
of the ABI wrapper, which is undesired.
In the syscall package in the standard library we changed to use
a compiler intrinsic internal/abi.FuncPCABI0 to take the address
of the syscall function. But that is not available to this repo
and not available in older versions of Go. Here we take a
different approach: taking the address directly from assembly.
This also ensures we get the address of the defined syscall
function, not the ABI wrapper.
Updates golang/go#45702.

Directly wrap the getcwd implementation provided by libSystem.dylib on
darwin and use it to implement Getwd like on the BSDs. This allows to
drop the custom implementation using getAttrList and to merge the
implementation of Getwd for darwin and the BSDs in syscall_bsd.go.

While the other BSDs use __sysctl as the name, Darwin now uses sysctl,
without the leading underscores, and considers __sysctl to be "private".
Using __sysctl leads to App Store rejections, and Go's syscall package
already uses the proper syscall. So this commit changes Darwin's syscall
to use it too here, while reverting a recent commit that removed it all
together on arm and arm64.
This reverts CL 194097.

Getdirentries is implemented with the __getdirentries64 function
in libSystem.dylib on darwin/{386,amd64}. That function can't be used in
an app store application.
Implement Getdirentries using the underlying
fdopendir/readdir_r/closedir for Go 1.13. The simulation isn't faithful,
and could be slow, but it should handle common cases.
For Go 1.12, fall back to raw syscalls since syscall.syscallPtr needed
to use fdopendir from libSystem.dylib is not available.
Follow CL 168479 and CL 170892 which did the same for syscall in the
stdlib.
Tested on darwin/amd64 with Go 1.11, Go 1.12 and Go 1.13

Call into libSystem (Darwin's libc equivalent) to do system calls.
Raw syscalls are not a supported ABI on Darwin, they want us to use
libSystem calls instead.
The stdlib has already been converted to this new regime. This
package is vendored into the stdlib, so we need to fix it also, then
vendor it in again.
Because this package isn't tied to a Go release, we need to keep the
old code around and use the new code only for 1.12 and up.
