Implement full console command completion

Drop the original console command completion patch and rewrite it
for JLine 3. Add support to complete command names instead of just
command arguments.

The additional single thread executor for command completion was
dropped because it's redundant: since the command completer needs
to wait for it to complete anyway, we might as well do the completion
directly from the console thread.
