Add u6rd-1.7.1 based on packaging provided in PR#47254

u6rd is a user-space 6rd (RFC 5569) implementation, which uses
tun(4) and the raw socket interface.

It runs on the 6rd border router of a 6rd site that is isolated from
the native IPv6 Internet.  In other words, it does not provide the
functionality of 6rd "relay" routers.
+u6rd
Added net/u6rd version 1.7.1
Adding the Creative Commons Attribution-NonCommercial-ShareAlike 3.0
Unported license. wip/celery is distributed under this license and that's
the only item barring its import into HEAD. cc-by-nc-sa-v3.0 is not being
added to DEFAULT_ACCEPTABLE_LICENSES, because there's no documentation
regarding its status on OSI nor FSF.
Updated to latest release 3.3.17. Remove py26 incompatibility directive.
This seems to have been fixed in a previous version. At least "import
billiard" works from the interpreter. From CHANGES.txt:

- Fixes SemLock on Python 3.4 (Issue #107) when using
  ``forking_enable(False)``.

- Pool: Include more useful exitcode information when processes exit.
Updated parallel/py-billiard to 3.3.0.17
Import py27-celery-3.1.11 as net/py-celery.

Celery is an asynchronous task queue/job queue based on distributed message
passing. It is focused on real-time operation, but supports scheduling as well.

The execution units, called tasks, are executed concurrently on a single or more
worker servers using multiprocessing, Eventlet, or gevent. Tasks can execute
asynchronously (in the background) or synchronously (wait until ready).
Added net/py-celery version 3.1.11
Fix dependency versions (unsaved edit).
Bump PKGREVISION

* Do not set plugin environmental variable
Updated www/firefox to 28.0nb4
Fix PR pkg/48726 for NetBSD 6.*

* Update sqlite3 requimenent version
Update to 0.12

* Security update for CVE-2013-6370 and CVE-2013-6371
* Update API version

0.12

  * Address security issues:
    * CVE-2013-6371: hash collision denial of service
    * CVE-2013-6370: buffer overflow if size_t is larger than int

  * Avoid potential overflow in json_object_get_double

  * Eliminate the mc_abort() function and MC_ABORT macro.

  * Make the json_tokener_errors array local.  It has been deprecated for
     a while, and json_tokener_error_desc() should be used instead.

  * change the floating point output format to %.17g so values with
     more than 6 digits show up in the output.

  * Remove the old libjson.so name compatibility support.  The library is
      only created as libjson-c.so now and headers are only installed
      into the ${prefix}/json-c directory.

  * When supported by the linker, add the -Bsymbolic-functions flag.

  * Various changes to fix the build on MSVC.

  * Make strict mode more strict:
    * number must not start with 0
    * no single-quote strings
    * no comments
    * trailing char not allowed
    * only allow lowercase literals

  * Added a json_object_new_double_s() convenience function to allow
    an exact string representation of a double to be specified when
    creating the object and use it in json_tokener_parse_ex() so
    a re-serialized object more exactly matches the input.

  * Add support NaN and Infinity
Updated textproc/json-c to 0.12
