Addition of libbitdht.

============================================================ This is intended to be a completely independent library from RS, (hosted at sf.net/projects/bitdht) hence is being commited at the top level. As initial further development / testing will be driven by RS integration it is being added to the RS repository. Equally important is ensuring that RS can compile without requiring aux libraries. Once libbitdht is further developed, this section of the repository is expected to be removed... But that will not be for a while, I expect. drbob. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@3276 b45a01b8-16f6-495d-af2f-9b41ad6348cc
