Jan Scheurich f839892a20 OF support and translation of generic encap and decap 
This commit adds support for the OpenFlow actions generic encap
and decap (as specified in ONF EXT-382) to the OVS control plane.

CLI syntax for encap action with properties:
  encap(<header>)
  encap(<header>(<prop>=<value>,<tlv>(<class>,<type>,<value>),...))

For example:
  encap(ethernet)
  encap(nsh(md_type=1))
  encap(nsh(md_type=2,tlv(0x1000,10,0x12345678),tlv(0x2000,20,0xfedcba9876543210)))

CLI syntax for decap action:
  decap()
  decap(packet_type(ns=<pt_ns>,type=<pt_type>))

For example:
  decap()
  decap(packet_type(ns=0,type=0xfffe))
  decap(packet_type(ns=1,type=0x894f))

The first header supported for encap and decap is "ethernet" to convert
packets between packet_type (1,Ethertype) and (0,0).

This commit also implements a skeleton for the translation of generic
encap and decap actions in ofproto-dpif and adds support to encap and
decap an Ethernet header.

In general translation of encap commits pending actions and then rewrites
struct flow in accordance with the new packet type and header. In the
case of encap(ethernet) it suffices to change the packet type from
(1, Ethertype) to (0,0) and set the dl_type accordingly. A new
pending_encap flag in xlate ctx is set to mark that an corresponding
datapath encap action must be triggered at the next commit. In the
case of encap(ethernet) ofproto generetas a push_eth action.

The general case for translation of decap() is to emit a datapath action
to decap the current outermost header and then recirculate the packet
to reparse the inner headers. In the special case of an Ethernet packet,
decap() just changes the packet type from (0,0) to (1, dl_type) without
a need to recirculate. The emission of the pop_eth action for the
datapath is postponed to the next commit.

Hence encap(ethernet) and decap() on an Ethernet packet are OF octions
that only incur a cost in the dataplane when a modifed packet is
actually committed, e.g. because it is sent out. They can freely be
used for normalizing the packet type in the OF pipeline without
degrading performance.

* Linux, FreeBSD, OpenBSD, and Windows.)
*
* - OpenFlow standard and vendor extension error codes use the range

/* OpenFlow error codes
* --------------------
*
* The comments below are parsed by the extract-ofp-errors program at build
* time and used to determine the mapping between "enum ofperr" constants and
* error type/code values used in the OpenFlow protocol:
*
* - The first part of each comment specifies the vendor, OpenFlow versions,
* type, and sometimes a code for each protocol that supports the error:
*
* # The vendor is OF for standard OpenFlow error codes. Otherwise it
* is one of the *_VENDOR_ID codes defined in openflow-common.h.
*
* # The version can specify a specific OpenFlow version, a version
* range delimited by "-", or an open-ended range with "+".
*
* # Standard OpenFlow errors have both a type and a code. Extension
* errors generally have only a type, no code. There is one
* exception: Nicira extension (NX) errors for OpenFlow 1.0 and 1.1
* have both a type and a code. (This means that the version
* specification for NX errors may not include version 1.0 or 1.1 (or
* both) along with version 1.2 or later, because the requirements
* for those versions are different.)
*
* - Additional text is a human-readable description of the meaning of each
* error, used to explain the error to the user. Any text enclosed in
* square brackets is omitted; this can be used to explain rationale for
* choice of error codes in the case where this is desirable.
*
*
* Expected duplications
* ---------------------
*
* Occasionally, in one version of OpenFlow a single named error can indicate
* two or more distinct errors, then a later version of OpenFlow splits those
* meanings into different error codes. When that happens, both errors are
* assigned the same value in the earlier version. That is ordinarily a
* mistake, so the build system reports an error. When that happens, add the
* error message to the list of "Expected duplications" below to suppress the
* error. In such a case, the named error defined earlier is how OVS
* interprets the earlier, merged form of the error.
*
* For example, OpenFlow 1.1 defined (3,5) as OFPBIC_UNSUP_EXP_INST, then
* OpenFlow 1.2 broke this error into OFPBIC_BAD_EXPERIMENTER as (3,5) and
* OFPBIC_BAD_EXT_TYPE as (3,6). To allow the OVS code to report just a single
* error code, instead of protocol version dependent errors, this list of
* errors only lists the latter two errors, giving both of them the same code
* (3,5) for OpenFlow 1.1. Then, when OVS serializes either error into
* OpenFlow 1.1, it uses the same code (3,5). In the other direction, when OVS
* deserializes (3,5) from OpenFlow 1.1, it translates it into
* OFPBIC_BAD_EXPERIMENTER (because its definition precedes that of
* OFPBIC_BAD_EXT_TYPE below). See the "encoding OFPBIC_* experimenter errors"
* and "decoding OFPBIC_* experimenter errors" tests in tests/ofp-errors.at for
* full details.
