Summary: trapsess in snmpd.conf can cause stderr logging to turn on

Initial Comment:
In net-snmp 5.5, but probably in earlier versions too, an snmpd.conf line such as

trapsess -v 3 -u trapdusr -l authPriv -Ci -a SHA -3k \
a3fbc81cbc5ffc7ee449efdb9587b3665a248d0c -x AES -3K \
e3bc7d9db5a1fb382e3a743f743d67e010317a08 1.2.3.4:5678

causes stderr logging to be turned on, even if snmpd was launched with arguments such \
as -Lf /dev/null -LS0-6d

This is because trapsess uses the common snmp_parse_args() handler to parse the \
trapsess line, and if snmp_parse_args() doesn't see an -L option, it calls \
snmp_enable_stderrlog() to turn on stderr logging.

This causes snmpd to fail to close fd's 0, 1 and 2 (even though it's still going into \
the background); this foils a system that waits for EOF from a popen()'d \
"/usr/sbin/snmpd" to learn that snmpd has successfully launched. 

A workaround is to repeat one of the logging options, such as -Lf /dev/null, on each \
trapsess line.
