e479bd56df Fix LWIP_ERROR macro - it should never be fatal (LWIP_ASSERT)
The only difference should be:
- LWIP_DEBUG enabled  -> print a diag message
- LWIP_DEBUG disabled -> NO diag message is printed

b1d3dcb8d7 tcp: don't reset dupack count upon non-empty packet receive
According to rfc5681:

https://tools.ietf.org/html/rfc5681

Paragraph 3.2.  Fast Retransmit/Fast Recovery
The TCP sender SHOULD use the "fast retransmit" algorithm to detect
and repair loss, based on incoming duplicate ACKs.  The fast
retransmit algorithm uses the arrival of 3 duplicate ACKs (as defined
in section 2, without any intervening ACKs which move SND.UNA) as an
indication that a segment has been lost.  After receiving 3 duplicate
ACKs, TCP performs a retransmission of what appears to be the missing
segment, without waiting for the retransmission timer to expire.

Now consider the following scenario:
Server sends packets to client P0, P1, P2 .. PK.
Client sends packets to server P`0 P`1 ... P`k.

I.e. it is a pipelined conversation. Now lets assume that P1 is lost, Client will
send an empty "duplicate" ack upon receive of P2, P3... In addition client will
also send a new packet with "Client Data", P`0 P`1 .. e.t.c. according to sever receive
window and client congestion window.

Current implementation resets "duplicate" ack count upon receive of packets from client
that holds new data. This in turn prevents server from fast recovery upon 3-duplicate acks
receive.
This is not required as in this case "sender unacknowledged window" is not moving.

b4be0d8808 mdns: added support for searching services
Two new API:
err_t mdns_search_service(const char *name, const char *service, enum mdns_sd_proto proto,
                          struct netif *netif, search_result_fn_t result_fn, void *arg,
                          s8_t *request_id);
void mdns_search_stop(s8_t request_id);

One compilation flags:
LWIP_MDNS_SEARCH

One options flags:
MDNS_MAX_REQUESTS

Some structure declarations moved to allow use by callback result function.

Result domain names are early uncompress before calling application callback
because it cannot be made by application itself.

Allow search services with multiples labels included, like '_services._dns-sd'.

Search for `_services._dns-sd._udp.local.` is handled in a special way.
Only `PTR` answers are send back to the application.

The `mdns_search_service()` function won't assert if no more space in `mdns_request`
table, just return an error if too many simultanous requests.

9263d44847 Small documentation fix for TFTP
Apparently the TFTP server now also invokes the error() function in the
tftp_context struct.

Some tftp clients (for example Windows 10 TFTP client) will open the
remote file before checking the local file can be opened - and will then
send an error indication to the server to indicate there was an error
opening the local file. When the happens, the LWIP tftp server will
invoke the error() member of the tftp_context.

8f2f43f093 Implement RFC4075 Receive SNTP servers via DHCPv6
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.

c02fea0961 PPP, PPPoE: use service name and concentrator name
Make pppoe_create() actually store the passed service name and
concentrator name, so that they are passed in the PADI/PADR/PADS
packets.

Assume that the user application won't be freeing the strings and just
copy the string pointers, therefore remove the mem_free() in
pppoe_destroy().

Since only the pointers are copied now, make them 'const' in
pppoe_softc.
