Until now, the default_port parameters to these functions have had
different types and different behavior. There is a reason for this, since
it makes sense to listen on a kernel-selected port but it does not make
sense to connect to a kernel-selected port, but this overlooks the
possibility that a caller might want to parse a string in the format
understood by inet_parse_active() without actually using it to connect to
a remote host. This commit makes the behavior consistent and updates all
the callers to work with the new semantics.

It is meaningful for user to check the stats of IPFIX.
Using IPFIX stats, user can know how much flows the system
can support. It is also can be used for performance check
of IPFIX.
IPFIX stats is added for per IPFIX exporter. If bridge IPFIX is
enabled on the bridge, the whole bridge will have one exporter.
For flow IPFIX, the system keeps per id (column in
Flow_Sample_Collector_Set) per exporter.
1) Add 'ovs-ofctl dump-ipfix-bridge SWITCH' to export IPFIX stats of
the bridge which enable bridge IPFIX. The output format:
NXST_IPFIX_BRIDGE reply (xid=0x2):
bridge ipfix: flows=0, current flows=0, sampled pkts=0, \
ipv4 ok=0, ipv6 ok=0, tx pkts=0
pkts errs=0, ipv4 errs=0, ipv6 errs=0, tx errs=0
2) Add 'ovs-ofctl dump-ipfix-flow SWITCH' to export IPFIX stats of
the bridge which enable flow IPFIX. The output format:
NXST_IPFIX_FLOW reply (xid=0x2): 2 ids
id 1: flows=4, current flows=4, sampled pkts=14, ipv4 ok=13, \
ipv6 ok=0, tx pkts=0
pkts errs=0, ipv4 errs=0, ipv6 errs=0, tx errs=0
id 2: flows=0, current flows=0, sampled pkts=0, ipv4 ok=0, \
ipv6 ok=0, tx pkts=0
pkts errs=0, ipv4 errs=0, ipv6 errs=0, tx errs=0
flows: the number of total flow records, including those exported.
current flows: the number of current flow records cached.
sampled pkts: Successfully sampled packet count.
ipv4 ok: successfully sampled IPv4 flow packet count.
ipv6 ok: Successfully sampled IPv6 flow packet count.
tx pkts: the count of IPFIX exported packets sent to the collector(s).
pkts errs: count of packets failed when sampling, maybe not supported or other error.
ipv4 errs: Count of IPV4 flow packet in the error packets.
ipv6 errs: Count of IPV6 flow packet in the error packets.
tx errs: the count of IPFIX exported packets failed when sending to the collector(s).
