of global utent/utxent variables. Only reuse the ut_id and maybe
the ut_host fields from utmp.
* lib/prototypes.h, libmisc/utmp.c: Removed checkutmp(),
setutmp(), setutmpx().
* lib/prototypes.h, libmisc/utmp.c: Added get_current_utmp(),
prepare_utmp(), prepare_utmpx(), setutmp(), setutmpx().
* libmisc/utmp.c (is_my_tty): Only compare the name of the utmp
line with ttyname(). (No stat of the two terminals to compare the
devices).
* libmisc/utmp.c: Use getaddrinfo() to get the address of the
host.
* configure.in: Check for getaddrinfo().
* configure.in: Use AC_CHECK_MEMBERS to check for the existence of
fields in the utmp/utmpx structures.
* configure.in: Reject systems with utmpx support but no ut_id
field in utmp. This could be fixed later if needed.
* src/login.c: Use the new utmp functions. This also simplifies
the failtmp() handling.
* src/login.c: passwd_free() renamed to pw_free() and
shadow_free() renamed to spw_free()
is always coming from xgetpwnam. There is no need to copy pwd to
pwent, this was not a good idea anyway as the strings from pwd
were not duplicated.
* src/login.c: Always free the pwd and spwd structure when we
retrieve a new one. This will clear the password of the previous
user from the memory.
* src/login.c: user_passwd is used to keep point to the password
of the user being authenticated.
* src/login.c: (non PAM) Fail if the user's entry cannot be found
after the user updated her password (if expire() requested an
update).
* src/login.c: If the user does not exist on the system, there is
no need to build a pwd structure (with shell).
username as first parameter of failtmp to avoid issues with
non-null terminated ut_user, unavailability of ut_user, incomplete
username (that should not happen currently).
terminal termio flags. Reset echoprt, noflsh, tostop. This
behavior seems to have change by mistake in earlier releases
(4.0.8, for no obvious reason).
utmp.c to chowntty.c. checkutmp() now only uses an existing utmp
entry if the pid matches and ut_line matches with the current tty.
This fixes a possible DOS when entries can be forged in the utmp
file.
* libmisc/chowntty.c, src/login.c, lib/prototypes.h: Remove the
tty argument from chown_tty. chown_tty always changes stdin and
does not need this argument anymore.
parameter of -f. Fix the getopt optstring, remove the parsing of
username in the -f processing block, and remove unnecessary checks
(username cannot be parsed twice anymore), better documentation of
the synopsis.
caller, not the user login tries to authenticate.
* src/login.c: Use pwd->pw_name instead of pwd->pw_uid. This might
be more precise (name must be unique, uid might not be).

src/groups.c, src/grpunconv.c, src/chsh.c: Prog is now global (not
static to the file) so that it can be used by the helper functions
of libmisc.
* lib/prototypes.h: Added extern char *Prog.
* libmisc/find_new_gid.c, libmisc/find_new_uid.c: Indicate the
program name with the warning.

Do it also in SYSLOG messages. Quote some parameters. All this
permits to merge some messages.
* src/login.c: Use a %lu format and cast group and user IDs to
unsigned long integers.
* src/login.c: Ignore return value of setlocale(),
bindtextdomain(), and textdomain().
* src/login.c: Ignore the return value of pam_end() before
exiting.
* src/login.c: Use a bool when possible instead of int integers.
* src/login.c: Add brackets and parenthesis.
* src/login.c: Ignore the return values of fflush(), putchar(), puts().
* src/login.c: Ignore the return value of fclose() for read-only
files.
* src/login.c: Avoid assignments in comparisons.
* src/login.c: Ignore return value of setlocale(),
bindtextdomain(), and textdomain().

endpwend() sequences (ditto for getgrent(), getspent(), and
getsgent()). The only real (minor) issue was in login, which kept
the passwd file open.
* libmisc/entry.c: Remove unneeded setspent() and endspent() (only
getspnam is called in the middle).
* libmisc/find_new_ids.c: Make sure to close the password and
group files with endpwent() and endgrent().
* libmisc/pwdcheck.c: Remove unneeded endspent() (only getspnam()
is called before).
* src/lastlog.c, src/passwd.c, src/groupmod.c, src/faillog.c,
src/groups.c: Make sure to close
the password file with endpwent().
* src/login.c: Remove unneeded setpwent() (only xgetpwnam is
called before).
* src/login.c, src/newgrp.c: Fix typos in comments.
src/chfn.c, src/passwd.c, src/chage.c, src/login.c, src/sulogin.c,
src/chsh.c: Fix call to puts (remove end of line, or use fputs).
* po/*.po: Unfuzzy PO files according to above change.
