fix bug in copy_string_to_graph, adjust n_free_words when copying pointers in an array (memory is allocated on the stack AND the heap)

fix timeout by checking the socket for errors

Closes iTasks-SDK#348

See merge request !4

In the old situation when the connect didn't immediately return, the
socket was placed in a select.
An error was throws only when the socket was in the exceptset. However,
sockets are only in the exceptset in very particular cases (see man
select). Unable to connect is not one of those cases.

Therefore to actually check if a connection was refused, the error
status must be checked with getsockopt.
