The Uplink_test used to end in an uncaucht exception about a failed packet allocation on several x86_32 platforms. * Destruct and re-construct the corresponding TX packet allocator during a link-down-up step in the Uplink test. Fixes the exceptions but results in a never ending test. * Decouple the link-down-up steps from the handling of packet stream signals by simply triggering it with a local periodic timeout of 1 sec period. This prevents that the Uplink_test never finishes because it destructs the Uplink connection too often. * The test finishes not before at least 3 link-down-up steps were executed. * Replace the Allocator_avl's used for the TX packet allocators of the Nic and Uplink Connection with the better suited Nic::Packet_allocator.
