sudo: updated to 1.8.23

Sudo 1.8.23

* PAM account management modules and BSD auto approval modules are
  now run even when no password is required.

* For kernel-based time stamps, if no terminal is present, fall
  back to parent-pid style time stamps.

* The new cvtsudoers utility replaces both the "sudoers2ldif" script
  and the "visudo -x" functionality.  It can read a file in either
  sudoers or LDIF format and produce JSON, LDIF or sudoers output.
  It is also possible to filter the generated output file by user,
  group or host name.

* The file, ldap and sss sudoers backends now share a common set
  of formatting functions for "sudo -l" output, which is also used
  by the cvtsudoers utility.

* The /run directory is now used in preference to /var/run if it
  exists.

* More accurate descriptions of the --with-rundir and --with-vardir
  configure options.

* The setpassent() and setgroupent() functions are now used on systems
  that support them to keep the passwd and group database open.
  Sudo performs a lot of passwd and group lookups so it can be
  beneficial to avoid opening and closing the files each time.

* The new case_insensitive_user and case_insensitive_group sudoers
  options can be used to control whether sudo does case-sensitive
  matching of users and groups in sudoers.  Case insensitive
  matching is now the default.

* Fixed a bug on some systems where sudo could hang on command
  exit when I/O logging was enabled.

* Fixed the build-time process start time test on Linux when the
  test is run from within a container.

* When determining which temporary directory to use, sudoedit now
  checks the directory for writability before using it.  Previously,
  sudoedit only performed an existence check.

* Sudo now includes an optional set of Monty Python-inspired insults.

* Fixed the execution of scripts with an associated digest (checksum)
  in sudoers on FreeBSD systems.  FreeBSD does not have a proper
  /dev/fd directory mounted by default and its fexecve(2) is not
  fully POSIX compliant when executing scripts.

* Chinese (Taiwan) translation for sudo from translationproject.org.
