This allows a big swath of ifdefs to be removed. It also means savings as the db var is not passed around all of the time, and makes it easier to remove the final broker call to mosquitto_time() call in packet_mosq.c. In one test this reduced the calls to mosquitto_time() from 295k to 48k.
In the mux_epoll__add_in function, no context->events was set. Previously this was set to match the ev.events (EPOLLIN). Adding this back in, keeps the code consistent to before it was refactored to split out epoll and poll functions, as well as being consistent with the other mux_epoll__ functions.
If this is not set, the connection is never fully established when the broker comes back up.
Fixes#1680.
