patch to cmuscheme: commands for tracing procedures and expanding syntactic forms

[Emilio Lopes]

Modern Scheme systems provide a myriad of debugging facilities to
their users.  Among the most ubiquitous features available are
mechanisms for tracing procedure calls as well as expansion of
syntactic forms.

This patch adds support for these features in the "cmuscheme"
library, including key bindings and customization for different
Scheme interpreters.
