r308160 (by bapt):
syslogd(8): add an 'include' keyword
All the '.conf' files not beginning with a '.' contained int he directory
following the keyword will be included.
This keyword can only be used in the first level configuration files.
Modify the default syslogd.conf to 'include' /etc/syslog.d and
/usr/local/etc/syslog.d
It simplify a lot handling of syslog from automation tools.
Relnotes: yes
r309194 (by bapt):
initialize *nextp which could be left uninitialized in case the configuration
file cannot be open/read
CID: 1365665
r309216 (by bapt):
Properly initialize nextp
