Fix log message weird suffixes.

I think these were leftovers from the removal of %z for MSVC that happened
some time ago.

ofproto: Use OFPRR_GROUP_DELETE

Use OFPRR_GROUP_DELETE as the reason for deleting flows due
to the removal of a group that they use.

This implementation adds an delete_reason member to struct ofputil_flow_mod
as a convenient way to set the reason used by delete_flows__() when it is
called indirectly from delete_group__().

OPENFLOW-1.1+: OFPRR_METER_DELETE is used

My reading of handle_delete_meter() is that OFPRR_METER_DELETE is used.
Accordingly delete the entry relating to it from OPENFLOW-1.1+.

lib/classifier: Fix incorrect pointer type.

This bug did not manifest due to 'hmap_node' being in the same offset
in both struct cls_partition and struct cls_subtable.

lib/cmap: Simplify iteration with C99 loop declaration.

This further eases porting existing hmap code to use cmap instead.

The iterator variants taking an explicit cursor are retained (renamed)
as they are needed when iteration is to be continued from the last
iterated node.

socket-util: Disable dscp setting on Windows.

According to msdn documentation, one is discouraged from using
IP_TOS for ipv4 sockets (it apparently does not actually set
anything). Also, IPV6_TCLASS does not work in
Windows (it always returns an error and also is undocumented).
Looks like Microsoft recommends QoS2 APIs to achieve
the same. Till we add those API calls, simply return on Windows.

(Noticed while running unit tests for ipv6. set_dscp would fail.)

ofproto-dpif: Move RECIRC_RULE_PRIORITY to common header

actions added as a result of processing (MPLS) actions.

ofproto-dpif: Add recirc_id field to struct rule_dpif

This is to allow a recirculation id to be associated with a rule
in the case that its actions cause recirculation.

In such a case if the recirc_id field is non-zero then that value should be
used, otherwise a value should be obtained using
ofproto_dpif_alloc_recirc_id and saved in recirc_id field.

When destructing the rule if the recirc_id field is non-zero then
the associated internal flow should be deleted.

This is in preparation for using the same helper as part of support
for using recirculation in conjunction series of actions including
with MPLS actions that are currently not able to be translated.

ofproto-dpif: Add idle_timeout parameter to ofproto_dpif_add_internal_flow()

This is in preparation for using the same helper as part of support

with MPLS actions that are currently not able to be translated.

In that scenario the idle timeout will be used to expire internal
rules that are added to handle recirculation.

userspace: add support for pop_eth and push_eth actions

These actions will allow L2->L3 and L3->L2 switching, and are supposed
to be added to flows installed in the datapath transparently by
ovs-vswitchd.

userspace: add layer 3 flow and switching support

This commit relaxes the assumption that all packets have an Ethernet
header, and adds support for layer 3 flows.  For each packet received on
the Linux kernel datapath the l2 and l3 members of struct ofpbuf are
intialized appropriately, and some functions now expect this (notably
flow_extract()), in order to differentiate between layer 2 and layer 3
packets.  struct flow has now a new 'base_layer' member, because we
cannot assume that a flow has no Ethernet header when eth_src and
eth_dst are 0.  For layer 3 packets, the protocol type is still stored
in the eth_type member.

Switching L2->L3 and L3->L2 are both implemented by adding the pop_eth
and push_eth actions respectively when a transition is detected.  The
push_eth action puts 0s on both source and destination MACs.  These
addresses can be modified with mod_dl_dst and mod_dl_src actions.

Added new prerequisite MFP_ETHERNET for fields MFF_ETH_SRC, MFF_ETH_DST,
MFF_VLAN_TCI, MFF_DL_VLAN, MFF_VLAN_VID and MFF_DL_VLAN_PCP.
