* Cherry-pick important fixes to 2.1.2-esp
- CVE-2020-22283: Attacker could craft a packet that would disclose 8 bytes of some heap memory:
- icmp6: Don't copy too much data
- icmp6: Fix copying of chained pbuf in reply
- icmp6: keep to the RFC and send as much as possible with icmp6 error messages
- CVE-2020-22284: ZEP - ZigBee Encapsulation Protocol/6LoWPAN is not supported in IDF,
the netif module (zepif.c) is not included in the build, but users can still inject
the file into compilation process, implement IO interface and use this.
- zepif: Copy possibly chained output pbuf properly
- Add #define for minimum IPv6 MTU length
- pbuf: Add pbuf_copy_partial_pbuf library function
* PPPoS: Fix null-deref when processing double break packet
- pppos: fix in_tail null (espressif/esp-lwip@537c69d5)
- PPP: Add test exhibiting empty packet null-deref (espressif/esp-lwip@202a07da)
* NAPT: Fix PBUF_REF type to clone the pbuf before forwarding
- IP-FORWARD: If packet-type is PBUF_REF clone it before forwarding
- Add NAPT unit test to exercise NAT feature for both RAM and REF pbuf types
* version: Update version numbers to match 2.1.2-esp
* Update submodule: 2749568fe1...76303df238
- test/napt: Add unit test for IP forward with PBUF_REF (espressif/esp-lwip@76303df2)

- version: Update version numbers to match 2.1.2-esp (espressif/esp-lwip@2b922919)
- pppos: fix in_tail null (espressif/esp-lwip@537c69d5)
- PPP: Add test exhibiting empty packet null-deref (espressif/esp-lwip@202a07da)

- icmp6: Fix copying of chained pbuf in reply (espressif/esp-lwip@7c822ff4)
- icmp6: keep to the RFC and send as much as possible with icmp6 error messages (espressif/esp-lwip@29100ab6)
- dns: Add API to clear dns cache (espressif/esp-lwip@ee59f77d)
- CI: Fixed adding gitlab key (espressif/esp-lwip@5a2bdba7)
- test case: modify test case test_tcp_new_max_num_remove_FIN_WAIT_1 (espressif/esp-lwip@6b090f7d)

Moved FreeRTOSConfig.h from include/freertos to include/esp_additions/freertos.
Updated FreeRTOS.h file to include FreeRTOSConfig.h without the
freertos/ prefix to match with the upstream file.
Renamed architecture specific FreeRTOSConfig.h files to FreeRTOSConfig_arch.h

LWIP has two definess for setting max number of sntp servers:
- Total number of handled servers
- max number of sntp's picked via DHCP
by default both values are equal to 1, but could be set separately

When client's request refused by sending NAK, its record still resided
in the linked list of pooled addresses. It is okay from the spec
perspective (RFC2131.p16: Server MAY mark the offered address
unavailable), but would consume some memory if the client didn't retry.

This commit brings two esp-lwip fixes to IDF:
1) Add configuration to disable DHCP client identification
2195f7416f
This config could be used to disable option 61 in DHCP packets, so that
clients will be identified by their chaddr only.
(This is the lwip upstream original behaviour)
2) Fix server_idx increasing to DNS_MAX_SERVERS and trigger the LWIP_ASSERT
5a567d52f7
When lwip doesn't have DNS server and resolve a domain address, the server_idx
will increase to DNS_MAX_SERVERS, which will trigger the LWIP_ASSERT and make device crash.
Closes https://github.com/espressif/esp-idf/issues/6878
