Proxy support should allow for retrieving the community
string from the incoming request to be proxied if the
proxy statement in the
snmpd.conf file does not contain the '-c' option.
Fix is forthcoming. Fix is to allow for omission of
when token statement parsed and to use the request
community string on the session when the request is
forwarded. ("on the session" == place c.s. temporarily
session data structure if current c.s. is NULL).
