Usability improvements to the emulab-sync programs: * Terminating a TCP client before the barrier is reached will back out any changes to the barrier's count. * You can SIGHUP the server to clear all of the barriers and release the clients with an exit value of 240. * Basic error reporting is supported using the "-e" option and the program's exit code. * On FreeBSD, the server will respond to a SIGINFO (^T) by printing out the list of active barriers. * More checking of the inputs.
