The LWIP_PBUF_MEMPOOL define used MEMP_ALIGN_SIZE instead of
LWIP_MEM_ALIGN_SIZE to calculate the element size of PBUF_POOL pbufs.
This is wrong for MEMP_OVERFLOW_CHECK, since MEMP_ALIGN_SIZE adds
MEMP_SANITY_REGION_AFTER_ALIGNED. This should be only added during
pool_base buffer allocation but for PBUF_POOL, it changed the size
of the pool elements.
This cleans up the code: sys_timeouts_mbox_fetch() was only used from
tcpip.c anyway, so let's move it there.

fuzz test revealed that an ip header with options might land in ip4_frag() via ICMP. In this case, we can't use LWIP_ERROR() to check for not having ip options as that might be defined to assert
The callers already ensure the ipaddr/netmask/gw won't be NULL, so remove
the duplicated NULL checking in these static functions.
While at it, also move the code saving old_address for netmask/gw as
it's only used when address is actually being changed.

Replace NULL pointers by IP4_ADDR_ANY4 - at sometime in the future, we make the NULL pointer handling obsolete and we can remove all the NULL pointer checks in the code
