A quick inspection of the net-snmp agent API indicates it is not
immediately suitable to be called from inside Squid. This due to a design
heavily centered around select() semantics and fd_set processing.

It may be possible to build glue around, but I have doubts in how the
library uses the fd_set:s. Any library having static/local fd_set
instances is not useable from Squid (filedescriptor limitation problem).

So for now I think it would be better to simply resurrect/reimplement the
TRAP PDU sending code. Since we are only looking at sending traps there is
not much danger or maintenance headache.
