This is especially important for distributions like NixOS where `/bin/bash` doesn't exist, or for MacOS users who've installed a newer version of Bash than the one that comes with their OS.

The LXC driver was deprecated in Docker 1.8.
Following the deprecation rules, we can remove a deprecated feature
after two major releases. LXC won't be supported anymore starting on Docker 1.10.

This allows someone running the image to use `-v` to mount a non-tmpfs `/tmp` into their image if they so require/desire.

Docker does not know about our named cpuacct,cpu,cpuset cgroup
hierarchy with multiple subsystems in it. So to use them with docker
in integration-cli test TestRunWithCpuset inside docker container
we need to add symlinks to them in hack/dind script.
Example:
old version of parser will do:
cat /proc/1/cgroup
11:cpu,cpuacct,name=my_cpu_cpuacct:/
...
and create and mount this hierarchy to directory
/cgroup/cpu,cpuacct,name=my_cpu_cpuacct/
so docker cannot find it because it has strange name
in new parser directory will be same as on host
/cgroup/my_cpu_cpuacct
and have symlinks for docker to find it
/cgroup/cpu -> /cgroup/my_cpu_cpuacct
/cgroup/cpuacct -> /cgroup/my_cpu_cpuacct
in other case if where is no name
cat /proc/1/cgroup
11:cpu,cpuacct:/
...
mount will be same for both parsers
/cgroup/cpu,cpuacct
and new one will also create symlinks
/cgroup/cpu -> /cgroup/cpu,cpuacct
/cgroup/cpuacct -> /cgroup/cpu,cpuacct

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.

Without this patch, containers inherit the open file descriptors of the daemon, so my "exec 42>&2" allows us to "echo >&42 some nasty error with some bad advice" directly into the daemon log. :)
Also, "hack/dind" was already doing this due to issues caused by the inheritance, so I'm removing that hack too since this patch obsoletes it by generalizing it for all containers.

These were found using `git grep -nE '[^-a-zA-Z0-9<>]-[a-zA-Z0-9]{2}'` (fair warning: _many_ false positives there).
