stat, lstat and dirstat now take struct param.

* ftw.c (ftw_callback): Pass nil to new parameter of
stat_to_struct, to have a new stat struct allocated as before.

* sysif.c (stat_to_struct, stat_impl, stat_wrap, lstat_wrap
dirstat): New optional parameter that lets caller specify an
existing struct object to fill.
(sysif_init): Adjust registrations of stat, fstat, lstat and
dirstat for new optional parameter.

* sysif.h (stat_to_struct, stat_wrap): Declarations updated.

* txr.1: Documented.
