In coda-5.3.5 (at least), install-server and install-client both
install "au" and "filcon". This causes a minor administrative problem
for the NetBSD packages constructed from those targets, coda-client-*
and coda-server-*. Installing both on the same machine produces
warnings, but worse, if someone installs the server, installs the
client, and then deinstalls the client, those programs will no longer
be present on the server. And vice-versa. Even if folks simply install
and upgrade both packages together, they're going to see warnings,
which will result in bug reports.

"filcon" looks to be a debugging tool, that could go either way, or
not at all. "au" seems pretty important, but is it reasonable to put
it only on the client? Do folks run servers without a client in the
same room (or on same machine)?

If not, if they can't go in one or the other, we have to factor out a
"coda-common" package, or something like that. Thoughts?
