This adds a small C binary for fighting zombies. It is mounted under
`/dev/init` and is prepended to the args specified by the user. You
enable it via a daemon flag, `dockerd --init`, as it is disable by
default for backwards compat.
You can also override the daemon option or specify this on a per
container basis with `docker run --init=true|false`.
You can test this by running a process like this as the pid 1 in a
container and see the extra zombie that appears in the container as it
is running.
```c
int main(int argc, char ** argv) {
pid_t pid = fork();
if (pid == 0) {
pid = fork();
if (pid == 0) {
exit(0);
}
sleep(3);
exit(0);
}
printf("got pid %d and exited\n", pid);
sleep(20);
}
```

This reduces memory usage with a lot of docker proxy processes.
On Docker for Mac we are currently carrying a patch to replace
the binary as we modify it to forward ports to the Mac rather
than the Linux VM, this allows us to simply replace this binary
in our packaging with one that has a compatible interface. This
patch does not provide an easy way to substitute a binary as
the interface is complex and there are few use cases, but where
needed this can be done.

This installs docker and dockerd to `$DOCKER_MAKE_INSTALL_PREFIX/bin`, which
defaults to `/usr/local/bin`

Currently the directory inside of the tgz files is /usr/local/bin
and this is causing some confusion, and problems with people who already
have stuff in those directories. This commit changes the directory
to /docker to help remove the confusion.

These are the changes required due to the new binaries that containerd introduced.
The rpm, and deb packages now include 5 binaries.
docker, containerd, containerd-shim, ctr, and runc
The tar files also include all 5 binaries.

Using "DEST" for our build artifacts inside individual bundlescripts was already well-established convention, but this officializes it by having `make.sh` itself set the variable and create the directory, also handling CYGWIN oddities in a single central place (instead of letting them spread outward from `hack/make/binary` like was definitely on their roadmap, whether they knew it or not; sneaky oddities).

The validation script from #10681 is too pedantic, and does not handle
well situations like:
```
cat <<EOF # or <<-EOF
Whether the leading whitespace is stripped out or not by bash
it should still be considered as valid.
EOF
```
This reverts commit 4e65c1c319.

Created a validation that detects all trailing whitespaces from every
text file that isn't *.go, *.md, vendor/*,
docs/theme/mkdocs/tipuesearch*
Removed trailing whitespaces from every text file except from vendor/*
builder/parser/testfiles*, docs/theme/mkdocs/tipuesearch* and *.md

This also removes the now-defunct `*maintainer*.sh` scripts that don't work with the new TOML format, and moves a couple not-build-or-release-related scripts to `contrib/` instead.

We might want to break it up into smaller pieces (eg. tools in one
place, documents in another) but let's worry about that later.
