Fix a problem not letting plugins work when the client is built on RedHat and derived systems (Fedora is affected too). Completely avoid apr_dso_load() on Linux (they modified it to open libraries with RTLD_NOW | RTLD_GLOBAL | RTLD_DEEPBIND). Get a standard DSO handle with RTLD_NOW | RTLD_GLOBAL flags instead, and convert it to a valid APR one by using apr_os_handle_put().
