Log Message:
PR bin/42464: Timothy McIntosh: Fix timed interoperability

Fix is a combination of FreeBSD fix and submitted patch.

[From the FreeBSD change]
The timed protocol is not implemented in a compatible way by all
vendors; the size of the tsp_name field is OS-dependent.  4.3BSD
used a 32-byte field, FreeBSD uses MAXHOSTNAMELEN and RedHat
apparently uses a 64-byte field.  As a result, sanity checking code
added a few months ago to detect short packets will fail when
interoperating with one of these other vendors.

Change the short packet detection code to expect a minimum packet
size corresponding to the 4.3BSD implementation, which should be
a safe minimum size.
