Ben Pfaff d12f128a31 ofp-errors: Fix bugs in treatment of OpenFlow experimenter errors. 
OpenFlow 1.2 and later have "experimenter errors".  The OVS implementation
was buggy in a few ways.  First, a bug in extract-ofp-errors prevented
OF1.2+ experimenter errors from being properly decoded.  Second,
OF1.2+ experimenter errors have only a type, not a code, whereas all other
types of errors (standard errors, OF1.0/1.1 Nicira extension errors) have
both, but extract-ofp-errors didn't properly enforce that.

This commit fixes both problems and improves existing tests to verify that
encoding and decoding of experimenter errors now works properly.

This commit also fixes the definition of OFPBIC_DUP_INST.  It claimed to
have an OF1.1 experimenter error value although OF1.1 didn't have
experimenter errors.  This commit changes it to use a Nicira extension
error in OF1.1 instead.

* Linux, FreeBSD, OpenBSD, and Windows.)

/* 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. */
