We want avocado tests to not require specific directories,
the user should be able to arrange them in the dir structure
they see fit. Also, if a test requires data, we suppose their
data dir is located in the same directory as the source file,
with the name:

[modulename].data

Re arrange the test dir to reflect this new structure.

Make the names used consistent between attributes and
methods inside the Test class.

This is a new implementation of avocado.utils.archive,
built upon Python stdlib zipfile and tarfile modules,
with a class that creates zip files or tarballs based on the filename
and a few helper functions, to create and extract compressed files.
