CVE-2019-14287: Fixed an issue where a user with sudo privileges
that allowed them to run commands with an arbitrary uid, could
run commands as root, despite being forbidden to do so in sudoers
(bsc#1153674).
Other issues fixed:
Cache resolved group names as calling getgrgid() is expensive and
on systems connected to AD with many users, groups or sudo rules
it causes sudo to take a long time to run (bsc#1068003).
Disable insults by default at build time. For new installations this
was done via sudoers file, but when upgrading from previous versions
it would accidentally be enabled (bsc#1053911).
Enable support for zlib compressed I/O logs (bsc#1058297).
