qpkg: converted ID comparison from "struct id *" to "void *"

Browse Source 
- id.h (struct tree, comp_id, make_tree), id.c (comp_id, make_tree):
  comparison function now takes "void *" (pointing to a "struct id")
  arguments instead of "struct id *", for compatibility with jrb
- id.c (comp_id, do_comp_id): added wrapper to convert "void *" back to
  "struct id *"
