SNMP option argument. That way the compiler will give a warning in
case of a missing or an extra but unknown 'case:'.
Do the same for SNMP LEAF objects to be prepared once gensnmptree will
auto-generate enums for those too.
Add an abort() after the switch() instead of the 'default:' to catch
any errors. The nice side effect is that the compiler will correctly
track supposed to be 'uninitialized' variables with that.
When trying to set a value sanity check it before calling the OS
dependent API of snmp_bridge to tell whether it is an attempt to
set a bad value or a general error.
