Pre-initialize libapreq2. Applications (except apache modules using mod_apreq2) should call this exactly once before they register custom parsers with libapreq2. mod_apreq2 does this automatically during the post-config phase, so modules that need call apreq_register_parser should create a post-config hook using APR_HOOK_MIDDLE.<p>
