* add an architecture guide to the documentation
* released without any changes
* increased default BUFSIZE to 16 kB to accept max headers of 8 kB which is
compatible with Apache. This limit can be configured in the makefile now.
Thanks to Eric Fehr for the checks.
* added a per-server "source" option which now makes it possible to bind to
a different source for each (potentially identical) server.
* changed cookie-based server selection slightly to allow several servers to
share a same cookie, thus making it possible to associate backup servers to
live servers and ease soft-stop for maintenance periods. (Alexander Lazic)
* added the cookie 'prefix' mode which makes it possible to use persistence
with thin clients which support only one cookie. The server name is prefixed
before the application cookie, and restore back.
* fixed the order of servers within an instance to match documentation. Now
the servers are *really* used in the order of their declaration. This is
particularly important when multiple backup servers are in use.
