Tobias Klauser 1fb6828e5b unix: convert Iovec.Base to *byte in mkpost.go on solaris 
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.

Fixes golang/go#55997

Tobias Klauser 3125361ba6 unix: allow overriding GOOS using GOOS_TARGET in mkpost.go 
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.

Follows CL 256278 which did the same for mksyscall.go

Tobias Klauser a3b23cc77e unix: use SYS_PTRACE in generated ptracePtr 
CL 469835 broke the syscall wrapper generation on linux and freebsd by
generating a wrapper for the inexistent SYS_PTRACE_PTR syscall. The
ptracePtr added by CL 469835 correctly uses SYS_PTRACE, likely because
it was manually edited in that CL. However, the incorrect SYS_PTRACE_PTR
syscall is used when regenerating the syscall wrappers.

Tobias Klauser e65921a090 unix/linux: use Go 1.19rc2 instead of building gotip 
CL 399336 added support for generating linux/loong64 types and constants
and CL 406794 switched it to use gotip after support for linux/loong64
was merged. The upcoming Go 1.19 release will support that platform, so
switch to use 1.19rc2.

Tobias Klauser af78867b19 unix/linux: update to Linux kernel 5.19-rc2 
Update to 5.19-rc2 instead of 5.18 for the following reasons:

- Support for LoongArch has been merged upstream. This allows to drop
  the loong64 specific kernel patches.
- Fixes [1] an issue encountered with when generating the
  SOCK_TXREHASH_DEFAULT constant from linux/socket.h on 5.18
- Contains a fix [2] to provide SYS_MEMFD_SECRET on linux/riscv64 as
  well, The underlying syscall was already available in earlier kernel
  versions. Also see golang/go#51547.

This also allows to drop the fallback to setattrlistTimes which was
used to set timestamps with nanosecond resolution before utimensat could

Tobias Klauser d61c044b16 unix: implement Pipe using pipe2 syscall on all linux platforms 
Most architectures currently already implement Pipe using the pipe2
syscall. Only 386, amd64, mips{,le}, ppc and sparc64 still use the pipe
syscall. However, some systems (e.g. Android seccomp policies) block
that syscall, see golang/go#40828 for an example.

The pipe2 syscall was added in Linux kernel version 2.6.27. The minimum
required Linux kernel version for Go 1.18 will be changed to 2.6.32
per golang/go#45964 so it is possible to unify the implementation of
Pipe using the pipe2 syscall.

Same as CL 350530 did for package syscall.

Tobias Klauser d19ff857e8 unix: on linux use accept4 in Accept, fall back to accept 
Android seems to block the accept syscall in newer versions. Use accept4
instead on kernel versions that support it (Linux 2.6.28 and newer) and
fall back to accept on ENOSYS.

Updates golang/go#45767

The zsyscall_darwin*.s files were regenerated using mksyscall.go. The
rest were updated manually, go fmt doesn't support formatting assembly
