Replace pre_connection module call with a register_hook call and
implement pre_connection as a hook. The intent is that these hooks will
be extended to allow Apache to be multi-protocol, and also to allow the
calling order to be specified on a per-hook/per-module basis. [Ben Laurie]
Port a bunch of modules to the new module structure.
