Task #11486: continuation. Now able to @(skip) through

a large file horizontally under @(freeform) in constant memory.
Position reporting is incorrect.

* match.c (match_line_ctx): New member, base.
(ml_all): Initialize new member to zero.
(consume_prefix): New static function.
(do_match_line): New static function, contains implementation of
match_line. Calls consume_prefix.
(match_line): Becomes a wrapper for do_match_line.
(search_form, h_skip): Call consume_prefix.
(freeform_prepare): New function. External to avoid inlining.
(v_freeform): Uses do_match_line, to down context by reference,
and also refactored to avoid spurious retention of c->data.

* unwind.c (uw_push-block, uw_push_env, uw_push_debug,
uw_push_catch): Zero out the structure, otherwise the unused
fields can cause spurious retention.
