Support function versions of if, and, or so that partial
evaluation like (op or @1 42) or (op if (eq @1 foo) bar xyzzy)
is possible.
* eval.c (do_eval): Change precedence between operator and
function lookup to favor operators. This is important since
there are several operators now which are also functions.
(if_fun, or_fun, and_fun): New static functions.
(eval_init): New functions registered as intrinsics.
* txr.1: Documented that if, and, or exist as both functions
and operators.
