* libnetworking/kern/uipc_socket2.c,
libnetworking/netinet/tcp_usrreq.c,
libnetworking/netinet/udp_usrreq.c,
libnetworking/rtems/rtems_bsdnet.h, libnetworking/rtems/rtems_glue.c:
Add configuration parameters for network stack efficiency multiplier
and default socket buffer sizes. Change default multiplier from 8 to
2 to match GNU/Linux. This has no impact on performance on the BSPs
tested.
