Tobias Klauser 3cf1e67d0c unix: don't fail TestPpoll on EINTR
TestPpoll sometimes fails builders due to Ppoll getting interrupted and
returning EINTR:

--- FAIL: TestPpoll (0.00s)
    syscall_linux_test.go:299: Ppoll: unexpected error: interrupted system call

Fix this by retrying Ppoll in case of EINTR, same as CL 298189 in
TestPoll.

Fixes golang/go#66324

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 530d0810a4 unix: add utimensat libc wrapper on darwin
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.

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.

For golang/go#45964
Fixes golang/go#40828

Tobias Klauser ed5796bab1 unix: implement EpollCreate using EpollCreate1 on all linux platforms
Most newer architectures (e.g. arm64 or riscv64) don't provide the
epoll_create syscall. Some systems (e.g. Android) block it even if it
were available. In the kernel, the epoll_create syscall is implemented
[1] the same way EpollCreate is implemented in this package for
platforms without the epoll_create syscall. Thus, avoid the separate
wrapper and consistently implement EpollCreate using EpollCreate1.

Tobias Klauser 6f6e22806c unix: implement InotifyInit using InotifyInit1 on all linux platforms
Most newer architectures (e.g. arm64 or riscv64) don't provide the
inotify_init syscall and some systems (e.g. Android) block it even if it
were available. Internally, the inotify_init syscall is implemented
exactly like inotify_init1 [1], so there is no point in having a
separate wrapper on some platforms.
