cyrus-imapd-2.4.17-caldav-beta4 released

Hi Sebastian,

The calendar and contact data is stored within a user's normal mailbox heirarchy.  imapd from cyrus-imapd-caldav-2.4.17 knows to not return the calendar and contact folders to an IMAP client in LIST output.

If you just copy the htttpd binary in place, I think it should work, but your IMAP users will see those folders.  At the very least they'll wonder what they are.  At the worst, they'll manipulate them with an IMAP client and make them unstable for CalDAV use.

If I missed anything, I'm sure Ken can chime in.

I have successfully installed and tested this version on a test VM. I'm
considering a limited test on our production server. There we run 2.4.17
built using Simon Matter's RPM. I wasn't able to adapt the SPEC file to use
the caldav-beta tgz, so I compiled manually using the same configure
parameters that Simon uses. Now I wonder if it would be considered safe to
manually install just the httpd binary and to use it alongside the ones
provided by the RPM?
