meta-flow: New library for working with fields by id.
OVS already has a fairly good set of functions for working with fields that
are known at compile time, but support for working with fields that are
known only at runtime is fairly limited (and fairly unneeded). However,
with NXM identifiers becoming more and more widely used throughout Nicira
extensions, it's becoming corresponding more and more common to need to
refer to fields at runtime. This new library represents a first attempt
at a systematic approach for doing so.

debian: Apply Ubuntu patch to add DKMS support.
I tested that installing openvswitch-datapath-dkms worked OK on my own
Debian machine.
The bulk of this patch is taken from downstream Ubuntu DKMS support written
by Chuck Short <zulcss@ubuntu.com>, version 1.2.0-1ubuntu1. I made the
following changes:
* Update debian/.gitignore.
* Update debian/automake.mk.
* Correct description in debian/control (it was a cut-and-paste from
the openvswitch-datapath-source description without editing).
* Fix up for --with-l26 to --with-linux and datapath/linux-2.6 to
datapath/linux transitions.
