splitting cmd.c, phase I

Preparation for moving enlightenment and conduct into new source
file insight.c.  Right now it's a stub that shouldn't break anything
whether included or omitted.  Once makefiles and project files have
been updated to compile and link it, the actual code will be moved.

unix/Makefile.src has been updated;
vms/Makefile.src and vmsbuild.com have been updated but not tested.
