* 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)
- napt: Fix PBUF_REF type to clone the pbuf before forwarding (espressif/esp-lwip@39068263)
- 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)
- pbuf: Add pbuf_copy_partial_pbuf library function (espressif/esp-lwip@1c9cd9c1)
- Add #define for minimum IPv6 MTU length (espressif/esp-lwip@d2dc577b)
- zepif: Copy possibly chained output pbuf properly (espressif/esp-lwip@64ab7f2a)
- icmp6: Don't copy too much data (espressif/esp-lwip@4a64731b)
- 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)

This commit updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
`lwip_select` uses `sys_arch_sem_wait` function making the assumption that it
is POSIX compliant. This commit makes that function wait for at least
timeout (milliseconds), as required by POSIX specification.

This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
In order to access DHCP messages from clients in different states
and possibly to implement custom handlers that alter the current state,
e.g. reject a client with specific hostname using NAK.
* Extended storage for staipassigned events to pass client's MAC address.
* Added client's MAC to dhcp server callback
* Posting the staipassigned events with clients IP and MAC address
This is a preparation for adding 6LoWPAN config options. We would
optionally add:
* "lwip/src/netif/lowpan6_common.c"
* "lwip/src/netif/lowpan6.c"
* "lwip/src/netif/lowpan6_ble.c"
But only if LWIP_LOWPAN6_SUPPORT is enabled in lwip menuconfig.

The following changes have been made:
1. All FreeRTOS kernel source files are now placed in the
freertos/FreeRTOS-Kernel folder to match with the upstream folder structure.
2. All kernel include files are now placed in freertos/FreeRTOS-Kernel/include.
3. All port files are now placed in freertos/FreeRTOS-Kernel/portable.
4. All additions/customizations are placed in freertos/esp_additions.
5. All other miscellaneous files (README, License files etc.) are moved to
freertos/FreeRTOS-Kernel folder to match with the upstream.
6. Updated esp-cryptoauthlib to latest commit to resolve FreeRTOS
include dependencies.

0 is a valid socket description, so should be accepted after we create a
socket. In IDF, though, it's just a theoretical issue, as customers have
to configure:
* FD_SETSIZE = CONFIG_LWIP_MAX_SOCKETS (from makefiles)
* CONFIG_VFS_SUPPORT_IO = n (from menuconfig)
(this configuration is currently broken, but if we adjust the IDF here
and there we could reproduce the issue)
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
