8e9fff1a3a unix: add CloseRange 
The close_range(2) syscall is available since Linux kernel v5.9,
with additional functionality of CLOSE_RANGE_CLOEXEC since v5.11.

No tests are required since this is a bare syscall.

88b6017d06 unix: don't fail TestPoll on EINTR from Poll 
Occassionaly TestPoll fails on some builders due to Poll getting
interrupted:

--- FAIL: TestPoll (0.00s)
    syscall_unix_test.go:516: Poll: unexpected error: interrupted system call
FAIL
FAIL	golang.org/x/sys/unix	0.956s

Fix this by retrying Poll in case of EINTR, same as CL 207861 did in
TestSelect.

a50acf3fe0 unix: fix IoctlFileDedupeRange test 
The test introduced in CL 284352 breaks on several builders, either
with IoctlFileDedupeRange returning ENOTTY (as already seen for android
in the TryBot run) or returning EINVAL in the FileDedupeRange.Status
field. Both seem to indicate that the underlying filesystem doesn't
support deduplication, so skip the test in these cases.

Also rename the test to indicate the func it is testing.

b80eb88b80 unix: add HIDRAW ioctls 
This change adds (most) of the ioctl API for the Linux HIDRAW interface.
Reading and writing non-numbered HID reports is done using the read and
write system calls respectively.

Some of the HIDIOC* request numbers are exported directly while others
are kept unexported. This is because some of the #defines require a len
attribute that doesn't have a specific well defined value.

Wrapper types are added for most of the request numbers as is standard.
No wrapper is added for HIDIOCGRDESCSIZE as it would just be
IoctlGetUint32.

The HIDIOC[GS]FEATURE, HIDIOC[GS]INPUT and HIDIOC[GS]OUTPUT request
numbers, which are required for numbered HID reports, are entirely
ommitted as the len attribute has to be a runtime variable. These could
be added later by doing something like
 `HIDIOCGFEATURE(0) | (len << _IOC_SIZESHIFT)`,
with care taken that len doesn't overflow _IOC_XSIZEMASK.

Outdated documentation for the HIDRAW interface is available at:
https://www.kernel.org/doc/Documentation/hid/hidraw.txt.

6f8348627a unix: fix darwin pipe implementation 
The raw syscall returned the two pipes whereas the libc call
takes a pointer to a location to write the two pipes.
When we switched over from raw syscalls to libc calls, this
change in behavior was missed.

760e229fe7 unix: test anyToSockaddr without creating actual socket 
Test_anyToSockaddr on linux needs to create a socket with the given
domain, type and protocol in order to test anyToSockaddr. Depending on
kernel version, permission and other factors, a given combination might
not be available on the system that runs the test, as is e.g. the case
for AF_CAN/SOCK_DGRAM/CAN_J1939 on several builders after CL 272767.

The only reason to create the socket is to be able to get the socket
protocol in anyToSockaddr using GetsockoptInt(..., SO_PROTOCOL). Move
this implementation into a wrapper func which can be overriden in tests
to with a func unconditionally returning the protocol under test. This
makes the test less dependent on the system it runs on and should fix
the builders broken by CL 272767.

While at it also removed the unused SocketSpec type in
syscall_internal_bsd_test.go and remove an unnecessary error var
declaration.

c5abc1b1d3 unix: revert zsysnum_darwin_*.go deletion from CL 250437 
CL 250437 removed the zsysnum_darwin_*.go files containing the SYS_*
contants for macOS. This was done assuming that users should migrate
away from direct syscalls to libSystem wrappers. Let's not force users
of this package on when they want to do that and re-add the
zsysnum_darwin_*.go files and mark the consts as deprecated.

We can still remove these once macOS actively prevents use of direct
syscalls.
