New macro: flow.

There has been interest in the community in a threading macro;
a triviality which which applies the opip syntax to a value.
Eschewing unusual glyph combinations like ->> and whatnot,
I've chosen the English word flow for this.

* share/txr/stdlib/op.tl (flow): New macro.

* lisplib.c (op_set_entries): Set up autoload for flow.

* txr.1: Documented.

* share/txr/stdlib/doc-syms.tl: Updated.
