Spamer script, desktop file and symlink for autostart.

Whem the database for clipped gets corrupted, it needs to be deleted and
the application restarted. Script that.

- More scripty (set -eu, not just an alias in a script).
- Update appstream data.

Git script to remove temp work tress and prune work trees.

The prune_ssh_sockets shell function would always delete the
ControlMaster sockets (the open file handlers would have a random suffix
and the check would always show that the socket wasn't open by any
process). Instead add a prefix to the ControlMaster sockets and ignore
them when pruning. Those sockets are always deleted when the process
exists. Also, mark the vim filetype for the ssh config fragments as
sshconfig.

Don't delete sockets that are still in use (have an open ssh client
listening).

So now I can run `$(eval docker remote hostname)`.

- Add toolbox script, bash completion.
- Better ansible-local in Makefile (match shell alias).
- Delete gcloud SDK bash completion, the mirror in github is gone.
- Update to newer version of binaries and vendored files.

In some cases (like a chroots or containers with minimal /dev)
/dev/stderr is not available. Replace outputting to fd 2 instead.

git grep -l '>> /dev/stderr' | xargs sed -i 's@>> /dev/stderr@>\&2@g'

Otherwise the files (as root) are written to my home directory and when
I correct the ownership I get this error: "Refusing to operate on a user
installation as root".

- Add missing symlink to the wrapper script, without it the scripts
can't be called as Vagrant commands.
- Fix pylint issues.

Too many changes in one commit that aren't relevant to each other all
because I didn't commit these for some time and they piled up, exactly
what I shouldn't do.

- Remove some Git submodules. They're not needed.
- Remove the REPREPRO_BASE_DIR environment variable, it's set with
direnv inside that project.
- Use Docker Buildkit.
- Use auto Python interpeter with Ansible, prefer Python3.
- Better ls aliases.
- Netcat aliases to listen and check ports and sockets.
- Aliases and functions for Terraform.
- Use Black to format Python code.
- Show the run duration and exit code in a line before the prompt, maybe
better with Bash earlier than 5.0, where there's an annoying with line
wrapping.
- Valid name for the flatpak_kill shell function.
- Delete user-dirs files, didn't do anything anyway.
- Convert README from reStructuredText to Markdown.
- Don't install gsutil with Python2, use snap to install the Google SDK.
- More pre-commit hooks, update the exiting ones, format the file for
yamllint, Use flake8 from it's repo, the one from the hooks repo is
deprecated.
- Clean the Shore SSH config.
- Add the shared AWS keys to the Endless SSH config.

Add dt (delayed tee), like tee but can output to the file that's being read from (for example sort foo.txt | dt foo.txt).

Add the docker remote sub-command (actually the _docker-remote script
but can be invoked as a sub-command with the wrapper script). It creates
a local socket that's forwarded to the dockerd socket on the remote host
via ssh. Requires OpenSSH 6.7 or later (for Unix socket forwarding and
%C token. Typical invocation would be `$(docker remote
host.domain.example)`. A blog post will follow.

So `_docker-dev` could be invoked as `docker dev` without `docker-dev`
getting in the way of tab completion. Renamed the current subcommands
accordingly.

- Vendored rabbitmqadmin, Bash completion.
- Use gsutil from PyPI, vendored Bash completion.
- Use gcloud from Snap, remove Docker aliases (it just for Linux
anyway).
- on-change, cw, mysqldump-loader Golang apps.
- importlab, remarshal Python apps.

- `exec` docker wrapper scripts.
- Added aws-sam-cli Python CLI, readded aws-shell Python CLI.

- Added Makefile to download the vendored and binary files.
- Replace gen-ssh-config with the said Makefile.
- Update all sorts of Bash completion files.
- Added `kompose` Bash completion file.
- Replace pythonrc submodule with said Makefile.
- Replace `bfg` shell function with said Makefile (and short shell
alias).
- Update Git hook to use Makefile, remove whatever was removed.
- Added `rc_update` shell alias to force update all said files.
- Added `kind` Golang binary.

Replace generated Bash completion scripts with ones that eval the output instead (instead of adding cleanup functionality to the gen-bash-completion script in case files linger in .bash_completion.d .

- Moved `monitor` from a shell function to a script, now it's callable
without mocking with the shell. Also, added an alias for `monitor` to
expand aliases after it.
- `sudome` is now a shell script instead of a function, now it works
around the `secure_path` option by trying to find the executable in the
path before calling `sudo`. Also, added an alias for `sudome` to expand
aliases after it.
- `__apt-daily` is now a shell script, it probably could have stayed a
shell alias but the quotes failed to pass the entire command to
`/bin/sh` as it was and I couldn't be arsed to solve it.
- Simplified `flatpak-daily`.
- `dd` shell alias is simpler and now the invocation `sudome dd` works
as expected (which was the whole point to begin with).
