Dropping the silly cons return value from txeval.

Two interfaces are provided to the function. One throws
on unbound variable, the other which evaluates them to the
symbol noval_s (used in exception handling).

* match.c (do_txeval): New static function.
(txeval): Functionality moved to do_txeval.
(txeval_allow_ub): New static function.
(vars_to_bindings, h_fun, v_freeform, v_next, v_merge, v_bind, v_set,
v_cat, v_output, v_deffilter, v_fun): No need to
use cdr to get the value from txeval.
(v_throw): Use txeval_ub_allowed, since unbound variables
are allowed in throw.
(v_try): Detect unbound arguments by checking for noval_s rather than
nil. No need to use cdr.
