* debug.c, debug.h (scm_reverse_lookup): Added.

Browse source 
(scm_procedure_name): Use scm_reverse_lookup to lookup the name of
internal procedure definitions; Don't use scm_i_inner_name.

* debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
procedure source before calling scm_unmemocopy instead of faking
an environment.
