Some places, particularly headers, were spewing warnings since they don't include neccessary other headers to get struct/enum definitions. Signed-off-by: David Lamparter <equinox@opensourcerouting.org> (cherry picked from commit 388f8857eb81ef75014060976776523a58a99389)

trap. The base OID will be prefixed to the provided OID and, if the

length is positive, the requested OID is assumed to be a columnar

object and the index OID will be appended.

The two first arguments are the MIB registry used to locate the trap

The use of the arguments may differ depending on the implementation

used.
