Russ Cox 9a76102bfb all: go fmt ./... 
Make all our package sources use Go 1.17 gofmt format
(adding //go:build lines).

Not strictly necessary but will avoid spurious changes
as files are edited.

Part of //go:build change (#41184).
See https://golang.org/design/draft-gobuild

Tobias Klauser e1471140ff unix: implement AF_SYSTEM/AF_SYS_CONTROL sockets on darwin 
See https://developer.apple.com/documentation/kernel/sockaddr_ctl for
details.

AF_SYSTEM is darwin-specific, so the BSD-specific anyToSockaddr func
needs to call GOOS-specific funcs which return nil, EAFNOSUPPORT on all
BSD platforms but darwin.

For golang/go#41868

Tobias Klauser 6f686a352d unix: add ErrnoName and SignalName 
Add ErrnoName and SignalName to get errno and signal name strings from
syscall.Errno and syscall.Signal values, respectively.

This repurposes the errors and signals vars (because they are not used
within x/sys/unix currently) and turns them into slices of struct,
containing errno/signal number, name and description. ErrnoName and
SignalName can then be trivially implemented using sort.Search.

Renaming errors to errorList additionaly allows to avoid package aliases
for the errors package.

Fixes golang/go#25134

Tobias Klauser 665f6529cc unix: add Uname on Darwin 
Darwin doesn't have a uname syscall but the same information can be
retrieved using sysctls. Use the raw sysctl numbers instead of doing the
roundtrip via SysctlString in order to void the additional sysctl calls
in nametomib and SysctlRaw.

This implementation follows the one in
https://opensource.apple.com/source/Libc/Libc-1244.1.7/gen/uname.c

Tobias Klauser 8413e589a2 unix: regenerate for macOS 10.13/iOS 11.1 
Update the syscall numbers and error constants on macOS 10.13 with iOS
SDK 11.1.

The removed syscalls are all removed or marked as deprecated/old in the
following list

  https://opensource.apple.com/source/xnu/xnu-4570.1.46/bsd/kern/syscalls.master

which according to

  https://opensource.apple.com/release/macos-1013.html

is the kernel version used for macOS 10.13.

The poll function was moved around because I missed to regenerate the
zsyscall_darwin_*.go files in CL 74290.
