Summary: snmpd: argument parsing causes segfaults

Initial Comment:
This is forwarded from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=444986:

Version 5.4.1 and 5.3.1.

From: ma...@ev... (Mark A. Hershberger)

$ sudo snmpd -LS
Segmentation fault
$ sudo snmpd -LE
Segmentation fault
$ sudo snmpd -LO
Segmentation fault

But argument parsing for the -LS option is messed up further:
$ sudo snmpd -LSwd
invalid syslog facility: S

Attached patch fixes the problem.

Also there are more instances of
optarg = argv[++optind];

These could of course cause even more segfaults then if optind+1 > argc...
