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
- Fix sys_untimeout implementation should not modify timer values since we are now using absolute timeouts.c
- Cleanup and simplify sys_check_timeouts() implementation
- Implement sys_restart_timeouts to rebase all timeouts based on next timer to expire
Changes by me:
- Rename TIME_LESS_THAN to TIME_LESS_OR_EQUAL_THAN
This can be used to post preallocated messages from an ISR to the tcpip thread
when using FreeRTOS, where where calls differ between task level and ISR level.

The netif_do_set_{ipaddr|netmask|gw} are static functions what won't be called
directly, thus move LWIP_ASSERT_CORE_LOCKED to netif_set_{ipaddr|netmask|gw}.
This avoid duplicated LWIP_ASSERT_CORE_LOCKED checking by netif_set_addr().

This ensures the core is locked when executing the init done function
passed to tcpip_init
The could manifest as a synchronization issue during early init if
another thread was in the LwIP context at the same time
This broke when IPv6 got scopes added. Scopes/zones are checked
even if none of the compared addresses are link local.
Result of the bug was that IPv6 replies were always sent unicast to
the source instead of to the multicast address.
Add ip-generic version that ignores IP zone info, since the v6 group
address is not tied to any netif.
This fixes a bug in tcp_split_unsent_seg() where a chained pbuf was
not correctly updating pcb->snd_queuelen during trimming and snd_queuelen
would desynchronize if pbuf_realloc() freed some of the chain
Also, use pbuf_clen() for adding the new remaining segment rather than ++.
The new remaining segment should always be one pbuf due to the semantics
of PBUF_RAM, but this follows the best practice of using pbuf_clen()
