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;
  }

05911fd4a1 lwip: Add dhcp servers post processing hook
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.

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.

72d54b68a6 lwip: dhcp-server fix static analysis warnings
1) kill_oldest_dhcps_pool() is only called when list has at least two members (assured with kconfig value limit), added assertion to ensure this function is used only when prerequisities are met
2) use after free reported in two places, since the analyzer checks also the scenario when the linked list has loops, added ignore tags

ffe043b1a8 esp_netif: Introduction of esp-netif component as a replacement of tcpip_adpter
- provides object oriented access to network intefaces
- not limited to default netifs
- more generic abstraction to network input output functions
- event handler registration removed from component responsibility
- backward compatibility layer for legacy tcpip_apapter APIs

Closes IDF-39

27cc0d1f91 modify the behavior for dhcpserver and tcpip_adapter:
1. dhcp_server: suppress send_offer debug output
2. tcpip_adapter: zero-initialize system_event_t structures
3. tcpip_adapter: pass client IP address along with SYSTEM_EVENT_AP_STAIPASSIGNED
