This adds support for RFC4075 SNTP server configuration via DHCPv6.
The DHCPv6 options transmitted are now conditional on how LwIP is
configured.
A new SNTP application option SNTP_GET_SERVERS_FROM_DHCPV6 is used
to enable. For simplicity this is configured to use the global
LWIP_DHCP6_GET_NTP_SRV configuration setting.
Tests:
- Check the global options now control the DHCPv6 request sent
in Wireshark
- Check against 0, 1 and 3 SNTP servers configured on an odhcpd
server configured to support RFC 4075 SNTP server lists.
Verify that the SNTP server list is updated on connection
establishment on an ESP8266 WeMOS D1.
- Verify that SNTP packets are sent and recieved from a
configured server and that system time is updated.

This reverts commit 1570dd8ad1c6afd2438dcb8b18d9eed794f78baa.
Buffering pcb->local_port is needed because TCP_PCB_REMOVE_ACTIVE()
sets it to 0 via tcp_pcb_remove() (comment: "reset the local port
to prevent the pcb from being 'bound'").

"sockets.c: Don't rely on #defines in socket.h to be in sync with ip.h
Map SO_* to SOF_* #defines"
Reported by Joan Lledó on mailinglist 6.Sep.2018
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.
