Log message:
simplify dynamic variable handling a great deal:
first remove all usage of Varq_Append by building the string directly.
then replace `common' handling with specialized handling for dynamic
strings (since they no longer need a buffer). Finally, identify the place
where the variable value needs to be copied because it's going to be free'd
or erased soon, and finally, use simple char* pointers.

Shaves about 80 bytes off every gnode structure, and kills quite a few
unnecessary malloc()s as well.
