which had still hardcoded descriptions or where we can't
use the standard print_usage_help_options macro.

The default readline tab completion that offers file listing from current

The readline offers editing capabilities while the user is entering the
line, unlike fgets(3) and getline(3) that were used earlier.

text-utils/tailf.c:69:21: warning: Using plain integer as NULL pointer
Since many 'struct option' has used zero as NULL make them more readable in
same go by reindenting, and using named argument requirements.

The current default is to print all usage() output. This is overkill
in many case.

* selinux/av_permissions.h and magic constants are deprecated, the
recommended solution is to use string_to_security_class() and
string_to_av_perm() to get access vector
* it also seems that selinux_check_passwd_access() does exactly the
same as our checkAccess(), let's use it.

The utils when compiled WITHOUT libuser then mkostemp()ing
"/etc/%s.XXXXXX" where the filename prefix is argv[0] basename.
An attacker could repeatedly execute the util with modified argv[0]
and after many many attempts mkostemp() may generate suffix which
makes sense. The result maybe temporary file with name like rc.status
ld.so.preload or krb5.keytab, etc.
Note that distros usually use libuser based ch{sh,fn} or stuff from
shadow-utils.
It's probably very minor security bug.

This change is a little bit messy, and requires a comment the struct
finfo should not have 'struct passwd *pw' as it's member. The earlier
struct design would have been burden to maintain, and confusing to use.

Commit db433bf737a5fd4e1c7cca5e3603934743eebd1c changed -u for --help to
-h, that is not true. The -h is short hand for --home-phone. And the
--version is accompanied with -v not -V.

The left and right white space trimming can be done with strutils.h
[lr]trim_whitespace() functions.
As a minor fix when user input exceeds maxium allowed gecos field length
the remaining characters in stdin are purged so that re-prompting works
correctly.
Additionally the prompt() is made to add message to check_gecos_string(),
so that there are less similar strings for translation project to deal.

Check for crypt.h existence, and use it if available over using unistd.h
for which a certain feature level has to be set to export a definition
for crypt. On Solaris this set causes a standards conflict in the
headers, because at the time of this check C99 mode is already enabled,
which implies certain standards non-compatible with _XOPEN_SOURCE.

This patch replaces a few functions used throughout the source:
* Renames getnum (from schedutils) to strtol_or_err
* Moves strtosize (from lib/strtosize.c)
* Moves xstrncpy (from include/xstrncpy.h)
* Adds strnlen, strnchr and strndup if not available (remove it from libmount utils)
A few Makefile.am files were modified to compile accordingly along with trivial renaming
in schedutils source code.

$ chsh
chsh: can only change local entries; use ypchsh instead.
The 'ypchsh' is an external util that does not have to be installed.
