filter out control characters and quote filenames

Searched for uses of putStr and hPutStr and changed appropriate ones to filter
out control characters and quote filenames.

This notably does not make find and findkeys quote filenames in their default
output. Because they should only do that when stdout is non a pipe.

A few commands like calckey and lookupkey seem too low-level to make sense to filter
output, so skipped those.

Also when relaying output from other commands that is not progress output,
have git-annex filter out control characters.
