genman, lib, tests: use defvarl where possible.

* genman.txr (dupes, tagnum): Replace defvar with defvarl.

* stdlib/doc-lookup.tl (os-symbol): Same.

* tests/011/macros-3.tl (x): Same.

* tests/011/mandel.txr (x-centre, y-centre, width, i-max, j-max, n)
(r-max, pixel-size, x-offset, y-offset): Same.
(file, colour-max): Delete (unused) variables.

* tests/012/circ.tl (x): Replace defvar with defvarl.

* tests/012/stack.tl (stack-limited): Same.

* tests/012/struct.tl (s): Same.

* tests/013/maze.tl (vi, pa, sc): Delete variables. Use
function arguments instead.
(usage): Fix typo.

* tests/014/dgram-stream.tl (family): Rename to...
(*family*): ...this.

* tests/014/socket-basic.tl (socktype): Rename to...
(*socktype*): ...this.
(%iters%): Replace defvar with defvarl.
