Michael Kerrisk d954cea8fd ftw.3: Reorganize the page to give primacy to nftw() 
nftw() is the better API, and POSIX.1-2008 marks ftw() obsolete.

Michael Kerrisk 3591ce3e19 ftw.3: ftw() and nftw() differ for the non-stat-able symlink case 
The POSIX specification of ftw() says that an un-stat-able
symlink may yield either FTW_NS or FTW_SL. The specification
of nftw() does not carry this statement.

Jann Horn a2ac97c78b getcwd.3: Note behavior for unreachable current working directory 
For the code that does this, see fs/dcache.c, search for
"prepend_unreachable".

Test case to demonstrate:

$ cat getcwd.c

int main(void) {
  unshare(CLONE_NEWUSER | CLONE_NEWNS);
  chdir("/usr");
  chroot("bin");

  printf("current directory: \"%s\"\n", get_current_dir_name());

  char *real = realpath(".", NULL);
  printf("realpath of .: \"%s\"\n", real ? real : "{none}");
  real = realpath("../home/jann/.ssh", NULL);
  printf("realpath of path: \"%s\"\n", real ? real : "{none}");

  return 0;
}
$ cat getcwd_test.c

int main(void) {
  unshare(CLONE_NEWUSER | CLONE_NEWNS);
  chdir("/usr");
  chroot("bin");
  printf("current directory: \"%s\"\n", get_current_dir_name());
  return 0;
}
$ gcc -o getcwd_test getcwd_test.c -Wall
$ ./getcwd_test
current directory: "(unreachable)/usr"

realpath.3 doesn't currently seem to handle this
case in a sane way, so I'm not going to document
its behavior yet. I'll report that as a bug instead.

Michael Kerrisk 4a1af09bd1 dlopen.3: Amend error in description of dlclose() behavior 
The current text says that unloading depends on whether
the reference count falls to zero *and no other libraries
are using symbols in this library*. That latter text has
been there since man-pages-1.29, but it seems rather dubious.
How could the implementation know whether other libraries
are still using symbols in this library? Furthermore, no
other implementation's man page mentions this point.
Seems best to drop this point.
