Core: use ngx_palloc_small() to allocate ngx_pool_large_t. This structure cannot be allocated as a large block anyway, otherwise that will result in infinite recursion, since each large allocation requires to allocate another ngx_pool_large_t. The room for the structure is guaranteed by the NGX_MIN_POOL_SIZE constant.
