Hash :3189eb00 Message :be_sock: handle readv() returns ECONNREFUSED (freebsd 9.2)
During testing sometimes bufferevent/bufferevent_connect_fail_eventcb fails,
and after some digging I found that this was the case when connect() doesn't
return ECONNREFUSED immediately, and instead next operation will return it (in
our case evbuffer_read()->readv(), needless to say that after this
bufferevent_writecb() called and it checks error with getsockopt() but of
course it doesn't return any error), so this patch checks "errno" after
"readv()" and installs "bufev::connection_refused" flag, to handle this from
writecb and only once.
Fixes: bufferevent/bufferevent_connect_fail_eventcb
Fixes: bufferevent/bufferevent_connect_fail_eventcb_defer
