JeffBezanson 43e8d1fbf0 adding the ability to heap-allocate extentions to the value stack,

and pushing arguments for both builtin functions and lambdas.
for now this is slower, but it was done in preparation for
Things To Come.

bytecode compiler. arguments are broken down into a nest of
list and nconc calls.
