e7a0a93a40 fix(lwip): Fix potential data-race in ping tcpip callback 
Need to use tcpip_api_call() instead of tcpip_callback(), since the
former waits for the tcpip task to complete and thus prevents potential
data races with subsequent TCP/IP tasks.

2822cc671a fix(lwip): Fix ping_v6 receiving to accept only echo replies 
This fixes a bug where we ping our own IP and the request itself
bounces back to the raw receive function and is incorrectly treated as
reply. (this bug was discovered when fixing ICMPv6 pings with incorrect
checksums, while the ping request was dropped in icmpv6.c due to wrong
checksum, but was also fed to raw layers where it was treated as
"correct" response, so the PINGv6 to ourselves still worked)

649816d9a1 fix(lwip/dhcps): Fallback DNS option to DHCP server's IP by default 
Adds backward compatibity option CONFIG_LWIP_DHCPS_ADD_DNS, which
prevents breaking changes.
This option should be removed in IDF v6.0

3035ce294d feat(esp_netif): add support for DHCP Option 114 captive portal URI 
DHCP Option 114 provides a modern method of indicating a captive
portal redirect to DHCP client. This introduces Option 114 to
the DHCPS component as well as provides examples for usage.

e8ee09d817 lwip/sntp: Fix esp_sntp_ API races 
Some of the esp_sntp_...() APIs that wrap lwip's SNTP
module use tcpip_callback() to execute the lwip functionality
in the correct state (either with locked TCP/IP core,
or within the TCP/IP thread).
tcpip_callback() however doesn't wait for completion of the callback,
which doesn't prevent from using the stack variables after destroy
if used as a parameter.
Introduced in a71fa82.
Fixed by using of tcpip_api_call() instead of the tcpip_callback().

b5d13b9837 lwip/dhcpserver: Support for adding extra opts 
This enables users appending an extra, user defined options in dhcp
server messages. Example of adding captive_portal option (160) to dhcp
offer message is provided:
* Add idf-lwip hook file (project makefile):
  idf_component_get_property(lwip lwip COMPONENT_LIB)
  target_compile_options(${lwip} PRIVATE "-I${PROJECT_DIR}/main")
  target_compile_definitions(${lwip} PRIVATE "-DESP_IDF_LWIP_HOOK_FILENAME=\"add_captive_portal.h\"")
* Implement appending (add_captive_portal.h):
  #pragma once
  #define LWIP_HOOK_DHCPS_POST_APPEND_OPTS(netif, dhcp, state, pp_opts) \
  if ((state)==DHCPOFFER) { *(pp_opts) = append_captive_portal_uri(*(pp_opts)); }
  static inline uint8_t *append_captive_portal_uri(uint8_t *optptr)
  {
    const static uint8_t DHCP_OPTION_CAPTIVE_PORTAL=160;
    const static char CAPTIVE_PORTAL_URI[]="my_uri";
    int size = sizeof(CAPTIVE_PORTAL_URI) - 1;
    *optptr++ = DHCP_OPTION_CAPTIVE_PORTAL;
    *optptr++ = size;
    for(int i = 0; i < size; ++i) {
        *optptr++ = CAPTIVE_PORTAL_URI[i];
    }
    return optptr;
  }

7b91343ca7 lwip: Fix ping socket create to allow for fd=0 
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)

96911fb7ea lwip: Fix DHCP Server to remove clients record if request not acked 
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.
