[PATCH v2 03/11] test-util-sockets: Clean up SocketAddress construction

[Markus Armbruster]

The thread functions build the SocketAddress from global variable
@abstract_sock_name and the tight flag passed as pointer
argument (either NULL or (gpointer)1).  There is no need for such
hackery; simply pass the SocketAddress instead.

While there, dumb down g_rand_int_range() to g_random_int().
