  open: detect FreeBSD bug
  
  open("link-to-file/", O_RDONLY) mistakenly succeeds.  The previous
  patch was enough to fix utimens when no fd is involved, but this is
  necessary for futimens to pass.
  
  * m4/open.m4 (gl_FUNC_OPEN): Also detect FreeBSD bug with slash on
  symlink.
  * doc/posix-functions/open.texi (open): Document the bug.
  * doc/posix-functions/utimes.texi (utimes): Likewise.
  * tests/test-open.h (test_open): Add parameters, and test symlink
  handling.
  * tests/test-open.c (main): Adjust caller.
  * tests/test-fcntl-safer.c (main): Likewise.
  * modules/open-tests (Depends-on): Add stdbool, symlink.
  * modules/fcntl-safer-tests (Depends-on): Likewise.
  * tests/test-openat.c (main): Add test-open tests.
