Details:


file: "lwip/opt.h"  add folowing #define

/**
 * MEMP_LIBC_MALLOC==1: Use malloc/free/realloc provided by your C-library
 * instead of the lwip internal allocator. Can save code size if you
 * already use it.
 */
#ifndef MEMP_LIBC_MALLOC
#define MEMP_LIBC_MALLOC                 0
#endif



file: "lwip/memp.c"

only const u16_t memp_sizes[MEMP_MAX] is used

memp_malloc(type) uses mem_malloc(memp_sizes[type]) instead of memp_memory
memp_free(type, mem) uses mem_free(mem) instead of memp_memory


I think it generates lesser code when using malloc/free with C-Library if the
compiler have them
