qdepends: rewrite to better match forward/backward dependencies

- dep: extract dependency functions into separate files for later reuse
- by default, report all deps for all *DEPEND combined (duplicates
  removed)
- allow listing per *DEPEND using -v, pretty-print and highlight the
  atoms seleted or queried for (-Q)
- support reverse querying multiple atoms
- make -Q output match forward output, highlight the match, to just
  print the match, use -q
