* Fix the use of strlcpy.

* Allow lists as arguments in commands by using '{' and '}'. The list
will be recursed and all '$' will be called, while '~' will only be
expanded when in the first element in the list. E.g "execute =
touch,{~/tmp/,$get_client_version=}"

* Added rak::path_expand that works on char buffers.

* Fixed RequestList::calculate_pipe_size so it doesn't request too
many pieces from fast peers.

* Added 'execute_log' for logging the result of calls to 'execute'.
