Add a simple tool to bind netatalk sockets and perform send operations.

This isn't a classic regression test in that it doesn't have a notion of
pass fail, it's more of an exercise tool.  It attempts to exercise
unbound, bound, unconnected, and connected variations on SOCK_DGRAM
sockets.

+ * This is a simple test tool to bind netatalk SOCK_DGRAM sockets and perform
+ * simple send operations that exercise each combination of bound and
+ * connected endpoints, with the intent of exercising the various kernel send
+ * case.
+ *
+ * In order to run this test, configure NETATALK into the kernel.  Use
+ * ifconfig to set an appletalk address on an interface.  Run this tool with
+ * two arguments: a local address and port number, and a remote address and
+ * port number.
+ *
+ * It is recommended that you try running it with some interesting address
+ * and port thresholds, including ATADDR_ANYNET, ATADDR_ANYNODE,
+ * ATADDR_ANYPORT, and ATADDR_ANYBCAST.  Try both remote unicast addresses
+ * and the local address, which will help to test local delivery (although
+ * not socket receive).
