recirc_id_pool_create() allocates memory but recirc_id_pool_destroy() did
not destroy it.

ovs-ofctl: Document 'cookie' argument to learn action.

This has always been supported, but the documentation was missing.

ovs-ofctl: Support "send_flow_rem" in "learn" actions.

This flag was overlooked when support for the "learn" action was added.
(It was always supported in the OpenFlow code, just not in the ovs-ofctl
interface.)

ofp-actions: Store cookie in network byte order in struct ofpact_learn.

Most other code in Open vSwitch that works with flow cookies keeps them
in network byte order.  Using network byte order in struct ofpact_learn,
also, reduces the number of byte order conversions needed across the
source tree.

netflow: Fold netflow_expire() into netflow_flow_clear().

netflow_flow_clear() asserted that no packets or bytes were included
in the statistics for the flow being cleared.  Before threading Open
vSwitch, this assertion was always true because netflow_expire() was
always called before calling netflow_flow_clear().  Since Open
vSwitch was threaded, however, it was possible that a packet arrived
after netflow_expire() but before netflow_flow_clear(), since each of
these function separately took the netflow mutex.

This commit fixes the problem by merging netflow_expire() into
netflow_flow_clear(), under a single acquisition of the netflow
mutex.

acinclude.m4: dpdk: link with -ldl if necessary

On some systems libintel_dpdk.a fails to link with libopenvswitch
unless -ldl is used. This should address the issue
