This reverts commit 8b4a8159a898795ef0fc9226dae1ce66531ad487.
We do not want to do this shortly before a release. Reformatting (buggy reformatting) may introduce new bugs.
When the network is changed, dhcp is rebooted.
It will send a dhcp request again to verify it's lease.
DHCP requests are send out in selecting state, rebinding, renewing
and rebooting. But in the rebooting state the hostname option is
not included. This means that after reboot, the hostname will be
unknown to the DNS.

This fixes an issue seen on MacOS with Clang 9.0.0:
../../../../lwip/src/core/ipv4/etharp.c:1069:142: error: format specifies type 'unsigned short' but the argument has type 'netif_addr_idx_t'
(aka 'unsigned char') [-Werror,-Wformat]
LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_query: dropped previously queued packet %p for ARP entry %"U16_F"\n", (void *)q, i));
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~
../../../../lwip/src/core/ipv4/etharp.c:1074:120: error: format specifies type 'unsigned short' but the argument has type 'netif_addr_idx_t'
(aka 'unsigned char') [-Werror,-Wformat]
LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_query: queued packet %p on ARP entry %"U16_F"\n", (void *)q, i));
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~
By default, netif_addr_idx_t is u8_t, so cast up to u16_t to match the format type
If a chained pbuf starts with DHCP_OPTION_PAD, an overflow check
triggers and the packet is ignored.
Fix this by changing the way the offset is increased for PAD.
Also ignore a packet that is missing the END option.

Can be combined into a single check using LWIP_MIN.

The new NULL checking against netif_input_fn make ppp stop working
because in ppp_new() it calls netif_add with NULL netif_input_fn.

Fix the case where nd6_send_rs() fails: send one solicitation here,
not LWIP_ND6_MAX_MULTICAST_SOLICIT.

... and add a unit test for it.
Moved resetting netif->rs_count from all reports to link-up and netif-up only.
While at it, clean up the interface a bit so that netif->rs_count is touched
from nd6.c only.

arp table functions, nd6 destination cache and struct netif_hint
can now be u16_t or u8_t depending on table size, so up to 32K
entries can be used in these tables (s16_t)

This should hide the internal type used for access to the ARP table
which currently is s8_t or u8_t, depending on the use case.
