First unit tests

Bugs that still remain:

• The socketaddr factory (DNS lookup) does not yet seam to be fully functional.
• UDP socket test needs to pass
• TCP socket test needs to pass
• Unit Test for socketaddr Factory lookups
• Segfault at test shutdown needs to be fixed.
• fcntl needs to be checked for correct flag retuns
