The whole idea of the patch-set introduce module for LuaJIT C tests. It
also, can be used for unit tests.
* The first patch is the prerequisite for the patch-set. It fixes
  LD_LIBRARY_PATH definition.
* The 2nd and 3d patches provides an API and helper for writing the tests.
* The last 2 patches rewrite existing tests that should be written in C in
  the proper way.

I'll be glad to hear some suggestions and ideas to improving the test
module:).
