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.
* src/pwck.c: Only unlock files if they were locked before (e.g.
not in read-only mode).
* src/pwck.c: Quote the username in error messages (harmonization
with other messages).
* libmisc/find_new_gid.c: Fixed typo (s/grp->gr_gid/group_id/).
* libmisc/find_new_gid.c: Likewise.
Thanks to Peter Vrabec.
* NEWS, libmisc/find_new_gid.c, libmisc/find_new_uid.c: Build an
index of used IDs to avoid a database request for each id in the
allowed range (when the highest allowed ID is already used).
This speedups the addition of users or groups when the highest
allowed ID is already used. The additional memory usage of the
tools should be acceptable when UID_MAX/SYS_UID_MAX are set to a
reasonable number.
undefining some configuration macros when the file is included
multiple times.
* libmisc/xgetXXbyYY.c, libmisc/xgetpwnam.c, libmisc/xgetpwuid.c,
libmisc/xgetgrgid.c, libmisc/xgetgrnam.c, libmisc/xgetspnam.c:
Include <config.h> from teh compiled C file, not the included
getXXbyYY.c.

src/groupadd.c, src/chage.c, src/login.c, src/grpconv.c,
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.
shadow_audit_result for the result argument of audit_logger().
This permits stronger type checking and a better readability of
the results (SHADOW_AUDIT_FAILURE/SHADOW_AUDIT_SUCCESS constants).
* src/groupadd.c, src/groupdel.c, src/useradd.c, src/userdel.c:
Use the SHADOW_AUDIT_FAILURE/SHADOW_AUDIT_SUCCESS results instead
of 0 or 1 in audit_logger().
* configure.in, libmisc/copydir.c: futimes() and lutimes() are not
standard. Check if they are implemented before using them. Do not
set the time of links if lutimes() does not exist, and use
utimes() as a replacement for futimes().
the list, not adduser. This fixes a segmentation fault for every
call of groupmems -d.
* libmisc/list.c: Add assertions to help identifying these issues.

booleans.

* libmisc/utmp.c: Avoid assignments in comparisons.
* lib/prototypes.h, libmisc/utmp.c: Change setutmp()'s prototype
to return an int because pututline() and pututxline() may fail.

integers to booleans.
* libmisc/limits.c: Ignore the return value of umask(). We will
never return to the original umask.
* libmisc/limits.c: Avoid multi-statements lines.
* libmisc/limits.c: Added default to a switch(). Report invalid
limit strings to syslog.
* libmisc/limits.c: Ignore the return value of fclose().
/etc/limits is open read-only.
* libmisc/limits.c: Ignore the return value of fputs() and
sleep().
* libmisc/limits.c: Check the return value of nice() and
set_filesize_limit(), and report errors to syslog.
* libmisc/ulimit.c, lib/prototypes.h: Return failures of
set_filesize_limit(). Change the prototype to return an int
instead of void.
libmisc/find_new_uid.c, libmisc/Makefile.am, lib/prototypes.h:
Split find_new_ids.c into find_new_gid.c and find_new_uid.c to
ease the description of login.defs variables in the different
tools.

case of failure when reading a faillog entry or writing in
faillog or btmp.

necessary.
