There is a data pending race involving late population of the streams in

This is caused by the fact that streams are added to the hash table only

This results in data_pending() incorrectly returning that there is no

Relayd "unique" ids wrap every 32-bit, and in some cases, negative

Change this to make the error value specifically -1ULL, use a direct
comparison (since we use an unsigned 64-bit integer, comparison with 0
becomes incorrect).
Since we now use a 64-bit ID, it is assumed to _never_ wrap-around
(remember, value -1ULL is an _error_). Therefore,
consumer_add_relayd_socket() can become much more strict than it was:
instead of accepting re-use of net_seq_idx, we can now assert that upon

This patch adds the session_id_per_pid to the channel creation message
