Lionel Sambuc 11be35a165 Importing NetBSD "Kyua" test framework 
To do so, a few dependencies have been imported:

 * external/bsd/lutok
 * external/mit/lua
 * external/public-domain/sqlite
 * external/public-domain/xz

The Kyua framework is the new generation of ATF (Automated Test
Framework), it is composed of:

 * external/bsd/atf
 * external/bsd/kyua-atf-compat
 * external/bsd/kyua-cli
 * external/bsd/kyua-tester
 * tests

Kyua/ATF being written in C++, it depends on libstdc++ which is
provided by GCC. As this is not part of the sources, Kyua is only
compiled when the native GCC utils are installed.

To install Kyua do the following:

 * In a cross-build enviromnent, add the following to the build.sh
   commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes

WARNING:
  At this point the import is still experimental, and not supported
  on native builds (a.k.a make build).

* Testing of atf_process_fork is quite messy. We want to be able to test
* all the possible combinations of stdout and stderr behavior to ensure
* that the streams are manipulated correctly.
*
* To do this, the do_fork function is a wrapper for atf_process_fork that
* issues stream-specific hooks before fork, while the child is running and
* after the child terminates. We then provide test cases that just call
* do_fork with different hooks.
*
* The hooks are described by base_stream, and we then have one *_stream
* type for ever possible stream behavior.
