To make the local build environment more correct and consistent, we
should never leave an uncommitted go.mod in the tree; however, we need a
go.mod for certain commands to work properly. Use a wrapper script to
create and destroy the go.mod as needed instead of potentially changing
tooling behavior by leaving it.
If a go.mod already exists, this script will warn and call the wrapped
command with GO111MODULE=on.

The 1.16 `io/fs` compatibility code was being built on 1.18 and 1.19.
Drop it completely as 1.16 is long EOL, and additionally drop 1.17 as it
has been EOL for a month and 1.18 is both the minimum Go supported by
the 20.10 branch, as well as a very easy jump from 1.17.

A copy of Go's archive/tar packge was vendored with a patch applied to
mitigate CVE-2019-14271. Vendoring standard library packages is not
supported by Go in module-aware mode, which is getting in the way of
maintenance. A different approach to mitigate the vulnerability is
needed which does not involve vendoring parts of the standard library.
glibc implements name service lookups such as users, groups and DNS
using a scheme known as Name Service Switch. The services are
implemented as modules, shared libraries which glibc dynamically links
into the process the first time a function requiring the module is
called. This is the crux of the vulnerability: if a process linked
against glibc chroots, then calls one of the functions implemented with
NSS for the first time, glibc may load NSS modules out of the chrooted
filesystem.
The API underlying the `docker cp` command is implemented by forking a
new process which chroots into the container's rootfs and writes a tar
stream of files from the container over standard output. It utilizes the
Go standard library's archive/tar package to write the tar stream. It
makes use of the tar.FileInfoHeader function to construct a tar.Header
value from an fs.FileInfo value. In modern versions of Go on *nix
platforms, FileInfoHeader will attempt to resolve the file's UID and GID
to their respective user and group names by calling the os/user
functions LookupId and LookupGroupId. The cgo implementation of os/user
on *nix performs lookups by calling the corresponding libc functions. So
when linked against glibc, calls to tar.FileInfoHeader after the
process has chrooted into the container's rootfs can have the side
effect of loading NSS modules from the container! Without any
mitigations, a malicious container image author can trivially get
arbitrary code execution by leveraging this vulnerability and escape the
chroot (which is not a sandbox) into the host.
Mitigate the vulnerability without patching or forking archive/tar by
hiding the OS-dependent file info from tar.FileInfoHeader which it needs
to perform the lookups. Without that information available it falls back
to populating the tar.Header with only the information obtainable
directly from the FileInfo value without making any calls into os/user.

The hack/vendor.sh script is used to (re)vendor dependencies. However, it did
not run `go mod tidy` before doing so, wheras the vendor _validation_ script
did.
This could result in vendor validation failing if go mod tidy resulted in
changes (which could be in `vendor.sum`).
In "usual" situations, this could be easily done by the user (`go mod tidy`
before running `go mod vendor`), but due to our (curent) uses of `vendor.mod`,
and having to first set up a (dummy) `go.mod`, this is more complicated.
Instead, just make the script do this, so that `hack/vendor.sh` will always
produce the expected result.

- use `vendor.mod` instead of `go.mod` to avoid issues to do with
use of CalVer, not SemVer
- ensure most of the dependency versions do not change
- only zookeeper client has to change (via docker/libkv#218) as
previously used version is no longer maintained and has missing
dependencies

Golang '.0' releases are released without a trailing .0 (i.e. go1.17
is equal to go1.17.0). For the base image, we want to specify the go
version including their patch release (golang:1.17 is equivalent to
go1.17.x), so adjust the script to also accept the trailing .0, because
otherwise the download-URL is not found:
hack/vendor.sh archive/tar
update vendored copy of archive/tar

- Fix the error message in hack/validate/vendor to specify that
hack/vendor.sh should be run instead of vndr.
- Fix hack/vendor.sh to also match on Windows paths for the whitelist.
This allows the script to be run on Windows via Git Bash.

This vendors a fork of logrus with fixes to deal with errors generated
by the github.com/pkg/errors package. Without these fixes, the errors
are mishandled when passed to WithError:
- When printing to a terminal (colors enabled), stack traces are
included in the error fields on a log line.
- When printing to a file (or with colors disabled), the error value is
missing entirely.
