sudo: updated to 1.8.27

What's new in Sudo 1.8.27

* On HP-UX, sudo will now update the utmps file when running a command
  in a pseudo-tty.  Previously, only the utmp and utmpx files were
  updated.

* Nanosecond precision file time stamps are now supported in HP-UX.

* Fixes and clarifications to the sudo plugin documentation.

* The sudo manuals no longer require extensive post-processing to
  hide system-specific features.  Conditionals in the roff source
  are now used instead.  This fixes corruption of the sudo manual
  on systems without BSD login classes.

* If an I/O logging plugin is configured but the plugin does not
  actually log any I/O, sudo will no longer force the command to
  be run in a pseudo-tty.

* The fix for bug 843 in sudo 1.8.24 was incomplete.  If the
  user's password was expired or needed to be updated, but no sudo
  password was required, the PAM handle was freed too early,
  resulting in a failure when processing PAM session modules.

* In visudo, it is now possible to specify the path to sudoers
  without using the -f option.

* Fixed a bug introduced in sudo 1.8.22 where the utmp (or utmpx)
  file would not be updated when a command was run in a pseudo-tty.

* Sudo now sets the silent flag when opening the PAM session except
  when running a shell via "sudo -s" or "sudo -i".  This prevents
  the pam_lastlog module from printing the last login information
  for each sudo command.

* Fixed the default AIX hard resource limit for the maximum number
  of files a user may have open.  If no hard limit for "nofiles"
  is explicitly set in /etc/security/limits, the default should
  be "unlimited".  Previously, the default hard limit was 8196.
