Reworked patches

Running unit test in the CI

Add as a separate commit

.gitlab-ci.yaml
test/unit/lwipopts.h
jira sync
unit test: tcp-state, PPP, NAPT

Reworked socket interface

Issue: Idiomatic C++ might have issues with some macros

Use upstream version
Add socket API that #undef's macros and create static-inline functions
LWIP_COMPAT_SOCKET_INET to include lwip_inet_ntop/pton()
lwip_{set/get}sockopt_impl_ext() -- maybe post upstream

Moved to port layer

Use upstream version and move patches to esp/post

sys_thread_sem_func(), sys_sem_signal_isr(), g_lwip_task
dns_clear_servers()
use custom_pbufs
ip4_route_src_hook() -> components/lwip/port/esp32/hooks/lwip_default_hooks.c
netif_update_hook on auto-ip, dhcp-cb, nd6-cb
PPP: pppapi_set_auth() thread safe
GARP to set user-timer
num sys timeout to be moved to lwipopts.h: LWIP_NUM_SYS_TIMEOUT_INTERNAL
define mem_clib_{m|c}alloc if CONFIG_WIFI_LWIP_ALLOCATION_FROM_SPIRAM_FIRST
ip6_autoconfig_enabled

DNS related changes

FALLBACK_DNS_SERVER_ADDRESS
Implement dns_server_is_set() for the dns_gethostbyname_addrtype() to fail if no-server set (not just the dns_servers[0])
