of struct ifchd_clients.

31d6d4cd92 Some options are never sent to ifchd, but we unfortunately would need to 
sacrifice type checking to remove them from the options table.  It may
be worth doing that, but I want to audit each call point before.

8caf9e7d7a Remove support for RFC868 Time Server options. Totally obsolete, and 
ifchd just had empty hooks that never received work messages anyway.

Shorten the names of ifchd commands.  This breaks wire protocol, but
thankfully I haven't released yet!

77af1d81fe Relicense under New BSD (2-clause) license. I don't see any advantage to 
restricting use unnecessarily, and simple attribution is fine.

8ede75738f When setting route, don't print an error if EEXIST is returned by the ioctl(). 
This 'error' merely means that the installed route already exists.

d72b24a2fe Theoretical correctness fix: 
Handle EAGAIN and EWOULDBLOCK more gracefully when dealing with safe_read().
All occurrences of safe_read() should only be invoked on fds that have signaled
ready-to-read state via the epoll() mechanism, so this change should not
result in any observable difference, but it is best to be safe.

Additionally, a constant stack variable is converted to an equivalent
macro define for cleanliness.

Finally, print the error type encountered if reading data from an ARP response
fails with a read error.
