dw_node assert

[tomcucinotta]

probably, all asserts in dw_node should be turned into some graceful shutdown of the connection, or lead to ignoring or returning an error for individual requests

$ ./dw_node -a parent --nt=2
epoll_ctl() failed while deleting socket: Bad file descriptor
dw_node: connection.c:127: conn_find_sock: Assertion `sock != -1' failed.
Aborted (core dumped)

$ ./dw_client -r 1000 -C 1 --nt 10 --ns 10

another one:

./dw_node -a parent --nt=6
dw_node: connection.c:263: conn_next_message: Assertion `m->req_size >= sizeof(message_t) && m->req_size <= BUF_SIZE' failed.
Aborted (core dumped)

not seeing this assert anymore in current master, is commit 47723053 perhaps fixing the issue someway? (how?)
