MINOR: stream: add a new target_addr entry in the stream structure

Browse Source 
The purpose will be to store the target address there and not to
allocate a connection just for this anymore. For now it's only placed
in the struct, a few fields were moved to plug some holes, and the
entry is freed on release (never allocated yet for now). This must
have no impact. Note that in order to fit, the store_count which
previously was an int was turned into a short, which is way more
than enough given that the hard-coded limit is 8.
