queue, dep: Dependent-value management.

Queues are useful data structures in their own right and a Lisp
implementation is handy.

Deps were inspired by Ken Tilton's Cells, but lack the latter's CLOS
trappings and probably its hairier features.  In particular, cyclic
dependencies are not permitted.
