Shell: Allow completions to request further action from the shell

Browse source 
The shell now expects a JSON object of the form {"kind":<kind>,...} per
line in the standard output of the completion process, where 'kind' is
one of:
- "plain": Just a plain suggestion.
- "program": Prompts the shell to complete a program name starting with
  the given "name".
- "proxy": Prompts the shell to act as if a completion for "argv" was
  requested.
- "path": Prompts the shell to complete a path given the "base" and
  "part" (same as completing part in cwd=base).
