Import lutok-0.3.

The main reason for this update is the addition of support for Lua 5.2,
which we will want to import sometime.

Released on 2013/06/14.

* Issue 1: Added support for Lua 5.2 while maintaining support for Lua
  5.1.  Applications using Lutok can be modified to use the new
  interface in this new version and thus support both Lua releases.
  However, because of incompatible changes to the Lua API, this release
  of Lutok is incompatible with previous releases as well.

* Issue 3: Tweaked configure to look for Lua using the pkg-config names
  lua-5.2 and lua-5.1.  These are the names used by FreeBSD.

Interface changes:

* New global constants: registry_index.

* New methods added to the state class: get_global_table.

* Removed global constants: globals_index.
Update kyua-cli to 0.7:

The major reason for this update is to support the just-imported lutok-0.3
and, in turn, support the eventual update of the in-tree lua to 5.2.

Changes:

Experimental version released on October 18th, 2013.

* Made failures from testers more resilent.  If a tester fails, the
  corresponding test case will be marked as broken instead of causing
  kyua to exit.

* Added the '--results-filter' option to the 'report-html' command and
  set its default value to skip passed results from HTML reports.  This
  is to keep these reports more succint and to avoid generating tons of
  detail files that will be, in general, useless.

* Switched to use Lutok 0.3 to gain compatibility with Lua 5.2.

* Issue 69: Cope with the lack of AM_PROG_AR in configure.ac, which
  first appeared in Automake 1.11.2.  Fixes a problem in Ubuntu 10.04
  LTS, which appears stuck in 1.11.1.
