When running in posix mode (for example, because it was invoked as `sh`,
or with the --posix option), bash rejects the function names previously
used because they contain hyphens, which are not legal POSIX names, and
exits immediately.
This is a particularly serious problem on a system in which the
following three conditions hold:
1. The `sh` executable is provided by bash, e. g. via a symlink
2. Gnome Display Manager is used to launch X sessions
3. Bash completion is loaded in the (system or user) profile file
instead of in the bashrc file
In that case, GDM's Xsession script (run with `sh`, i. e., bash in posix
mode) sources the profile files, thus causing the shell to load the bash
completion files. Upon encountering the non-POSIX-compliant function
names, bash would then exit, immediately ending the X session.
Fixes#521.

This adds a basic bash auto-completion profile.
It supports 3 things at this time:
- Auto-complete of container name (-n or -o)
- Auto-complete of template name (-t)
- Auto-complete of state names (-s)
It's configured in a way to be as little disruptive as possible, any
argument that's not explicitly handled by the profile will fallack to
bash's default completion.
