- add patch to modify apr1 poll() emulation to match behavior expected by serf
serf depends on the poll emulation in apr returning a POLLERR event if a
non-blocking connect() attempt fails in order to trigger an IPv6 -> IPv4
fallback, or a fallback to another address for a multi-homed host. On
FreeBSD, the poll emulation is done using kqueue, and the result returned by
the poll() emulation is POLLIN + POLLHUP.
