netdev-dpdk: Add new DPDK RFC 4115 egress policer

This patch adds a new policer to the DPDK datapath based on RFC 4115's
Two-Rate, Three-Color marker. It's a two-level hierarchical policer
which first does a color-blind marking of the traffic at the queue
level, followed by a color-aware marking at the port level. At the end
traffic marked as Green or Yellow is forwarded, Red is dropped. For
details on how traffic is marked, see RFC 4115.

This implementation could probably be folded into the existing
egress-policer with the only side effect that it needs to run through
two meters. The configuration would be backwards compatible as the
default queue's configuration will be the same as the port. The initial
reason for having a separate implementation was to fix/find bugs related
to adding an additional policer.

This patch also does not yet include the documentation/vswitch.xml update,
will add this when this patch moves from an RFC patch to a real one.

Note this patch needs to be applied to dpdk-latest with the appropriates latest
DPDK version.

v1 -> v2:
  Rebase so it would apply to the dpdk-latest branch and latest DPDK master
