New destructuring operators.
* eval.c (tree_case_s, tree_bind_s): New symbol variables.
(bind_macro_params): Bugfix: inappropriate exception thrown when atom
matched against parameter list. Bugfix: nil being returned when
atom matches empty parameter list. Added support for a new convention:
if loose_p is the colon keyword, then exceptions are not thrown
for destructuring mismatches; nil is returned instad.
(op_tree_case, expand_tree_cases, expand_tree_case, op_tree_bind):
New static functions.
(expand): Handle tree_case_s and tree_bind_s.
(eval_init): Intern tree-case and tree-bind symbols.
Register the corresponding operator functions op_tree_case and
op_tree_bind under these symbols in op_table.
* txr.1: Documented tree-case and tree-bind operators.
