Make C globals in TXR Lisp properly assignable, so that for instance

assigning *stdout*, it really overwrites the underlying C variable.

* eval.c (lookup_var): Handle new kind of toplevel binding.
If the hash value is a cptr, it points to a val storage location.
(lookup_val_l): New function.
(op_modplace): Get location of variable using lookup_val_l
rather than assuming there is a cons-based binding.
(reg_var): Argument changed to val * pointer.
Register the variable as a cptr referencing the location.
(eval_init): reg_var calls pass address of each global.

* eval.h (lookup_var_l): Declared.
