description:
Syslog: logging level of connect() errors.

Connecting to syslog server might legitimately fail: for example, if
syslogd is not running, and the connection is made over a unix socket.
As such, the "alert" logging level is not appropriate.  Changed
logging level to "crit" instead, similarly to the logging level used
for connect() errors in resolver.
