Update 1.8.19p1 --> 1.8.19p2.

Major changes between sudo 1.8.19p2 and 1.8.19p1:

• Fixed a crash in visudo introduced in sudo 1.8.9 when an IP address or network is used in a host-based Defaults entry. Bug #766
• Added a missing check for the ignore_iolog_errors flag when the sudoers plugin generates the I/O log file path name.
• Fixed a typo in sudo's vsyslog() replacement that resulted in garbage being logged to syslog.
