  same-inode, stat-size: support pointers too
  
  Add functions and macros so that we can test pointers to struct
  stat as well as plain struct stat.  This lets coreutils deal with
  structs that are only partly initialized, without relying on
  undefined behavior.
  * NEWS: Mention this.
  * doc/posix-headers/sys_stat.texi, doc/stat-size.texi:
  Mention this and modernize.
  * lib/at-func2.c (at_func2):
  * lib/fts.c (same_fd):
  * lib/rename.c (rpl_rename) [RENAME_HARD_LINK_BUG]:
  * lib/same-inode.c: New file.
  * lib/same.c (same_nameat):
  * lib/term-style-control.c (activate_term_style_controller):
  Prefer psame_inode (a, b) to SAME_INODE (*a, *b).
  * lib/hash-triple-simple.c (triple_compare_ino_str):
  * lib/hash-triple.c (triple_compare):
  Prefer PSAME_INODE (a, b) to SAME_INODE (*a, *b).
  psame_inode is not suitable since the args are not struct stat *.
  * lib/same-inode.h: Check that config.h is included first.
  (SAME_INODE_INLINE, PSAME_INODE): New macros.
  (SAME_INODE): Reimplement in terms of PSAME_INODE.
  (psame_inode): New function.
  * lib/stat-size.h (STP_BLKSIZE, STP_NBLOCKS): New macros.
  (ST_BLKSIZE, ST_NBLOCKS): Use them.
  * lib/term-style-control.c (log_signal_handler_called):
  Always define as a function, to pacify -Wunused*.
  * modules/canonicalize-lgpl-tests (Files): Add m4/musl.m4.
  (Depends-on): Call gl_MUSL_LIBC.
  * modules/same-inode (Files): Add same-inode.c.
  (Depends-on): Add extern-inline, stdbool.
  (lib_SOURCES): New macro.
  * tests/test-binary-io.c, tests/test-canonicalize-lgpl.c:
  * tests/test-canonicalize.c, tests/test-cloexec.c:
  * tests/test-dup-safer.c, tests/test-dup2.c, tests/test-error.c:

  * tests/test-sigprocmask.c, tests/test-snprintf.c:
  * tests/test-stat.h, tests/test-term-style-control-hello.c:
  * tests/test-term-style-control-yes.c, tests/test-thread_create.c:
  * tests/test-unlinkat.c, tests/test-vasnprintf.c:
  * tests/test-xalloc-die.c:
  Adjust to these changes, and fix some warnings elicited by
  -Wall -Wextra that I ran into while testing.
  * top/maint.mk (sc_prohibit_stat_st_blocks): Mention STP_NBLOCKS.
