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.

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

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.

bce67f0961 unix: add SetsockoptTCPRepairOpt on Linux 
There is currently no function to allow for setting repair options for sockets in repair mode.
There are 4 options catered for in the linux implementation.

TCPOPT_WINDOW
TCPOPT_MAXSEG
TCPOPT_SACK_PERMITTED
TCPOPT_TIMESTAMP

Details of the patch to the kernel and the thinking behind it is here  https://lwn.net/Articles/495304

Work done in this commit
Included the tcp options type and length for inclusion in the Docker build
Added TCPOPT to the regular expression in mkerrors.sh. There was only TCP_ previously
Add the new function to syscall_unix.go

I have tested locally and verified each option with ss -i

I am not sure whether to commit tests because I don't know if socket creation is possible on the test runs in the offical pipeline.
I did check for existing tests but didn't see any that created sockets, only one that validated a string option.

b1c119fd70 unix: move ICMP{,V6}_FILTER* const definitions 
The C headers defining these constants pull in <netinet/in.h> which
leads to definition conflicts between kernel and glibc headers when
running mkerrors.sh for Linux kernel 5.13. Avoid these by moving this
const definitions to linux/types.go.

For golang/go#47057

b4502255bf unix: generate ioctlPtr on Linux with unsafe.Pointer arg 
The existing ioctl stubs for all UNIX-like platforms take a value of type
uintptr for the arg parameter. However, arguments which are cast from
unsafe.Pointer to uintptr technically violate the rules for package unsafe.
unsafe only allows a conversion from unsafe.Pointer to uintptr directly
within a call to Syscall.

ioctl is used on all UNIX-like operating systems and each one will have
to be updated accordingly where pointer arguments are passed to system
calls. To remedy this on Linux, we generate a new function called
ioctlPtr which takes a value of type unsafe.Pointer for arg. More
operating systems can be updated in future CLs by folks who have access
to those systems and can run the appropriate code generator.

Updates golang/go#44834

e5e7981a10 unix: add ifreq and ifreqData helpers for Linux 
ifreq is difficult to use in Go due to the union field in particular. This
situation is made worse due to the need to comply with Go's unsafe.Pointer
rules. This CL generates the raw ifreq type and also adds an ifreqData type
of the same size which is specialized for use with unsafe.Pointer.

We also replace the existing ifreqEthtool (which was not padded to the correct
size) with the new APIs and add a test to verify that IoctlGetEthtoolDrvinfo
functions properly by checking the name of the driver for each network interface.

Future uses of ifreq in package unix can expand upon this type with additional
getter and setter methods to deal with the unsafe casts to and from the union
byte array. We may also consider exporting ifreq and ifreqData if necessary.

59db8d763f unix: add bindings for kinfo_proc on Darwin 
On Linux, we can extract a list of all the processes on the system by
calling readdir() against /proc. On BSD-like systems, this information
needs to be extracted from sysctl in the form of kinfo_proc structures.

This change adds bindings for this structure and adds a method for
reading an array of these structures from sysctl.
