Note: besides the esp-netif component, this commit also disables
net_sockets.c from mbedtls, which is one of the base components and uses BSD API (not specifically lwIP). This might be refactored to use CONFIG_SUPPORT_BSD_API instead of CONFIG_ESP_NETIF_TCPIP_LWIP
in the future.
It also disables smartconfig_ack.c and wifi_init.c from esp_wifi
component for referencing some lwIP config options (smartconfig_ack.c changes might be also
updated to check CONFIG_SUPPORT_BSD_API)
Merges https://github.com/espressif/esp-idf/pull/5856
On update of any interface (set up/down) a routing preference is updated calling esp_netif_update_default_netif() that is called from
lwip context. But if the related netif was ppp type, the set_default api used user-mode, thus causing a dead lock.
