This improves the general abstraction of OXM/NXM by eliminating direct
knowledge of it from the meta-flow code and other places.
Some function renaming might be called for; for example, mf_oxm_header()
may not be the best name now that the function is implemented within
nx-match. However, these renamings would make this commit larger and
harder to review, so I'm postponing them.

This is a first step toward improving the abstraction of OXM and NXM in the
tree. As an immediate improvement, this commit removes all of the
definitions of the OXM and NXM constants from the top-level header files,
because they are no longer used anywhere.

Until now, knowledge about OpenFlow has been somewhat scattered around the
tree. Some of it is in ofp-actions, some of it is in ofp-util, some in
separate files for individual actions, and most of the wire format
declarations are in include/openflow. This commit centralizes all of that
in ofp-actions.
Encoding and decoding OpenFlow actions was previously broken up by OpenFlow
version. This was OK with only OpenFlow 1.0 and 1.1, but each additional
version added a new wrapper around the existing ones, which started to
become hard to understand. This commit merges all of the processing for
the different versions, to the extent that they are similar, making the
version differences clearer.
Previously, ofp-actions contained OpenFlow encoding and decoding, plus
ofpact formatting, but OpenFlow parsing was separated into ofp-parse, which
seems an odd division. This commit moves the parsing code into ofp-actions
with the rest of the code.
Before this commit, the four main bits of code associated with a particular
ofpact--OpenFlow encoding and decoding, ofpact formatting and parsing--were
all found far away from each other. This often made it hard to see what
was going on for a particular ofpact, since you had to search around to
many different pieces of code. This commit reorganizes so that all of the
code for a given ofpact is in a single place.
As a code refactoring, this commit has little visible behavioral change.
The update to ofproto-dpif.at illustrates one minor bug fix as a side
effect: a flow that was added with the action "dec_ttl" (a standard
OpenFlow action) was previously formatted as "dec_ttl(0)" (using a Nicira
extension to specifically direct packets bounced to the controller because
of too-low TTL), but after this commit it is correctly formatted as
"dec_ttl".
The other visible effect is to drop support for the Nicira extension
dec_ttl action in OpenFlow 1.1 and later in favor of the equivalent
standard action. It seems unlikely that anyone was really using the
Nicira extension in OF1.1 or later.

Until now, sets of actions have been abstracted separately outside
ofp-actions, as enum ofputil_action_bitmap. Drawing sets of actions into
ofp-actions, as done in this commit, makes for a better overall
abstraction of actions, with better consistency.
A big part of this commit is shifting from using ofp12_table_stats as if
it were an abstraction for OpenFlow table stats, toward using a new
struct ofputil_table_stats, which is what we generally do with other
OpenFlow structures and fits better with the rest of the code.

The translation into OpenFlow 1.2 didn't trim off the OpenFlow 1.3 specific
bits. This fixes the problem.
It would probably be wise to introduce an ofputil_table_stats structure.
Using ofp12_table_stats is somewhat confusing.

OpenFlow 1.2 standardized experimenter error codes in a way different from
the Nicira extension. This commit implements the OpenFlow 1.2+ version.
This commit also makes it easy to add error codes for new experimenter IDs
by adding new *_VENDOR_ID definitions to openflow-common.h.

Initial OpenFlow 1.3 support with new include/openflow/openflow-1.3.h.
Most of the messages that differ from 1.2 are implemented. OFPT_SET_ASYNC
is implemented via NX_SET_ASYNC_CONFIG, other new message types are yet to
be implemented. Stats replies that add duration fields are implemented at
encode/decode level only. Test cases for implemented features are included.
Remaining FIXME:s should not cause runtime aborts. Make check comes out
clean.

OpenFlow 1.1 and 1.2 action numbering is compatible, in that no
OpenFlow 1.2 action uses an OpenFlow 1.1 action number in a different
way from OpenFlow 1.1. So it's confusing and unnecessary to have
separate definitions for these numbers.

OpenFlow headers are not as uniform as they could be, with size, alignment,
and numbering changes from one version to another and across varieties
(e.g. ordinary messages vs. "stats" messages). Until now the Open vSwitch
internal APIs haven't done a good job of abstracting those differences in
header formats. This commit changes that; from this commit forward very
little code actually needs to understand the header format or numbering.
Instead, it can just encode or decode, or pull or put, the header using
a more abstract API using the ofpraw_, ofptype_, and other APIs in the
new ofp-msgs module.

This code, which leverages the existing NXM implementation,
adds parsing and serialisation of OXM matches. Test cases
have also been provided.
This patch only implements parsing and serialisation of OXM fields that
are already handled by NXM.
It should be noted that in OXM ports are 32bit whereas in NXM they
are 16 bit. This has been handled as a special case as all other field
widths are the same in both OXM and NXM.
This patch does not address differences in wildcarding between OXM and NXM.
It is planned that liberal wildcarding policy dictated by either OXM or
NXM will be implemented.
This patch also does not address any (subtle?) differences between
OXM and NXM treatment of specific fields. It is envisages that his
can be handled by subsequent patches.
