Add C writing utility scripts

Cdec is simply a combination of cdec and cnoname, and ctrace is a
janky sed script (in which -i may be passed) that tries to tell you
when functions have been entered and left. It is imperfect, but can
be useful (although there's certainly a better way of doing it).

(These have existed for a long time, but were never added for one
reason or another.)
