The Go "os" package already provides bindings for SEEK_CUR, SEEK_SET and
SEEK_END. Most operating systems also support SEEK_HOLE and SEEK_DATA,
which you can use to skip sparse regions in a file. Let's add bindings,
so we can also do this from within Go.

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.

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.

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.

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

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.
