better debuggability for interpreted procedures
* libguile/procprop.c (scm_set_procedure_minimum_arity_x): New
function, allows a user to override a function's arity.
(scm_i_procedure_arity): Look up in the overrides table first.
* libguile/procprop.h: Add scm_set_procedure_minimum_arity_x.
* module/ice-9/eval.scm (primitive-eval): Override arity of "general
closures".
* test-suite/tests/procprop.test ("procedure-arity"): Add tests.
Based on a patch from Stefan Israelsson Tampe. Test based on work by
Patrick Bernaud.
