Fix the rest of the apr_pool_userdata_setn() bogosity w.r.t. DSO modules.
It's totally unsafe to use apr_pool_userdata_setn() in the post_config
phase of a module, since on some platforms when the DSO gets reloaded
between phases, the data segment will be at a different address on the
second phase and the userdata_get() call will fail.
