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.

(cherry picked from commit 8f2f43f0937dcb192351f89df78157a814f37b21)
TLS clients that need 2-way authentication (e.g. Amazon AWS IoT cloud mqtt)
need to pass a certificate and private key when creating the tls altcp_pcb.
Added a new function altcp_tls_create_config_client_2wayauth() for this that
replaces altcp_tls_create_config_client() for such clients.
See bug #54601.
e.g. if the calling stack should not invoke the mdns functions due
to high stack usage, disable the option and trigger it yourself.

Fail to build if PPP_SUPPORT is disabled because PPP_NUM_TIMEOUTS
references defines that are unknown if PPP_SUPPORT == 0. Move
PPP_NUM_TIMEOUTS to PPP_SUPPORT block and set a default value to 0
if PPP_NUM_TIMEOUTS is still not defined at the end of ppp_opts.h.

A deep analysis of simultaneously running timers showed we can use a
slightly smaller value for PPP_NUM_TIMEOUTS_PER_PCB, value which was
arbitrarily chosen to a safe value based on the number of enabled PPP
features. Add the boring and long analysis to the end of our internal
header file and use the result in ppp_opts.h.

Only the transmission side works for now (todo: dual and tradeoff mode).
Also, only a 10 second timeout mode is implemented for now.

We never use the current peer NS value but always the next expected peer
NS value (current value plus one).

... 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.

This timeout is used to measure TFTP_TIMEOUT_MSECS fine enough.
Calling tftp_tmr at a 50ms interval to handle a 1 seconds timeout
produces way too much cpu load (and prevents sleep).
