prior to this change, global_init() could create a new CephContext and assign it to g_ceph_context. it's our responsibilty to release the CephContext explicitly using cct->put() before the application quits. but sometimes, we fail to do so. in this change, global_init() will return an intrusive_ptr<CephContext>, which calls `g_ceph_context->put()` in its dtor. this ensures that the CephContext is always destroyed before main() returns. so the log is flushed before _log_exp_length is destroyed. there are two cases where global_pre_init() is called directly. - ceph_conf.cc: g_ceph_context->put() will be called by an intrusive_ptr<> deleter. - rgw_main.cc: global_init() is called later on on the success code path, so it will be taken care of.
