project: banish need for C compiler

This patch gets rid of the thin veneer that we currently have around the three
executables.  This was done for historical reasons (circa 2003 Guile couldnʼt
deal with process signals and forks).  In fact these problems were fixed many
moons ago, and there is now no need for it.  The project becomes 100% Guile!

Many files are affected; interested coders should use the GIT repository to
understand the details of all the changes.
