Well it should be in crypto/objects.h, the one you need is:
ASN1_OBJECT * OBJ_txt2obj(const char *s, int no_name);
it was added fairly recently. To handle general OIDs you need the
ASN1_OBJECT structure. Only OIDs in OpenSSLs internal table have a
usable NID, those not in there all have the NID NID_undef, whereas
arbitrary OIDs can be represented by an ASN1_OBJECT.
