The commit configures the masks generated from megaflows and pushes
them through the dpif layer.
With this commit and a wildcard supporting OVS kernel module,
ovs-vswitchd's flow setup rate is very close to that of the Linux
bridge.

In addition to the changes to ofproto, this commit changes all of the
instances of "struct flow" in the tree so that the "in_port" member is an
OpenFlow port number. Previously, this member was an OpenFlow port number
in some cases and an ODP port number in other cases.
Until now, packet processing in ovs-vswitchd has been split between two
components: ofproto, for basic OpenFlow functionality, and bridge, for
OFPP_NORMAL processing. This architecture will not work as Open vSwitch
starts to support a wider variety of underlying hardware, because it
imposes a model in which the bridge needs to be able to look at every
exact-match flow within a OpenFlow flow, which most hardware doesn't
support.
Therefore, this commit moves all of the packet processing code in
bridge into ofproto, as preparation for generalizing further.
This is intended to provide controllers enough information to determine
whether a switch is overloaded or busted, to enable them to spread load
fairly across a group of switches.
Feature #2421.
