[PATCH 0/5] *.[ch]: don't duplicate *_init() and *_INIT logic

This series implements a suggestion by Jeff King to use an idiom for *_init() functions that avoids duplicating what we've declared in the corresponding *_INIT macros. See https://lore.kernel.org/git/YNytp0JAIaQih0Y4@coredump.intra.peff.net/

Ævar Arnfjörð Bjarmason (5):
  *.h: move some *_INIT to designated initializers
  *.c *_init(): define in terms of corresponding *_INIT macro
  dir.[ch]: replace dir_init() with DIR_INIT
  string-list.[ch]: add a string_list_init_{nodup,dup}()
  string-list.h users: change to use *_{nodup,dup}()
