  fcntl: use to simplify other modules
  
  Let fcntl do the work, instead of copying code into other modules.
  
  * modules/cloexec (Depends-on): Add fcntl.
  * modules/fchdir (Depends-on): Likewise.
  * modules/fd-safer-flag (Depends-on): Likewise.
  * modules/unistd-safer (Depends-on): Likewise.
  * modules/dup3 (configure.ac): Set module indicator.
  * m4/fchdir.m4 (gl_FUNC_FCHDIR): Replace fcntl if fchdir is
  missing.
  * lib/fchdir.c (_gl_register_dup): Fix comment.
  * lib/cloexec.c (dup_cloexec): Simplify, by relying on fcntl.
  * lib/dup-safer.c (dup_safer): Likewise.
  * lib/dup-safer-flag.c (dup_safer_flag): Likewise.
  * lib/dup3.c (dup3): Likewise.
  * tests/test-fchdir.c (main): Enhance test.
  Fixes a dup_cloexec bug reported by Ondřej Vašík.
