Remove the netievent remnants

Browse Source 
After removing all functional netievents, remove what has been left from
the netievents.  This also includes leftovers from previous refactorings.

* The macros here are used to simulate the "inheritance" in C, there's the base
* netievent structure that contains just its own type and socket, and there are
* extended netievent types that also have handles or requests or other data.
*
* The macros here ensure that:
*
* 1. every netievent type has matching definition, declaration and
* implementation
*
* 2. we handle all the netievent types of same subclass the same, e.g. if the
* extended netievent contains handle, we always attach to the handle in
* the ctor and detach from the handle in dtor.
*
* There are three macros here for each netievent subclass:
*
* 1. NETIEVENT_*_TYPE(type) creates the typedef for each type; used below in
* this header
*
* 2. NETIEVENT_*_DECL(type) generates the declaration of the get and put
* functions (isc__nm_get_netievent_* and isc__nm_put_netievent_*); used
* below in this header
*
* 3. NETIEVENT_*_DEF(type) generates the definition of the functions; used
* either in netmgr.c or matching protocol file (e.g. udp.c, tcp.c, etc.)
