Allow carp(4) to be loaded as a kernel module. Follow precedent set by bridge(4), lagg(4) etc. and make use of function pointers and pf_proto_register() to hook carp into the network stack. Currently, because of the uncertainty about whether the unload path is free of race condition panics, unloads are disallowed by default. Compiling with CARPMOD_CAN_UNLOAD in CFLAGS removes this anti foot shooting measure. This commit requires IP6PROTOSPACER, introduced in r211115.
