Added lwIP hooks which could be optionally overwritten in the
application code. These three options are provided in Kconfig:
* NONE: No hook support
* DEFAULT: Default implementation is provided. If IDF doesn't
have a specific hook implementation, an empty stub is provided, which
could be overwritten by strong implementation in application code.
* CUSTOM: Hooks are declared only to be implemented in application code.

When setting hostname using esp_netif_set_hostname_api() failed for some reason, the netif pointer might be freed while lwip pointer stil point to that location and could be used. Fixed by moving the freeing and string duplication to the block where lwip hostname is set.
Closes https://github.com/espressif/esp-idf/issues/6048
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)

* changing dependencies from unity->cmock
* added component.mk and Makefile.projbuild
* ignore test dir in gen_esp_err_to_name.py
* added some brief introduction of CMock in IDF
Extended test cases for DHCP server and DHCP client state transitions to include also manual transitions using esp_netif_dhcps_start/stop() esp_netif_dhcpc_start/stop()
The interface name can be used in socket API, i.e. setsockopt(). The API esp_netif_get_netif_impl_name() shoudl be used to populate standard
interface structure struct ifreq.
Use the configured esp-netif netmask to update the dhcp struct when
starting the server or starting the netif itself.
Use the netmask in dhcps setters and getters.
calling esp_netif_up() and esp_netif_down() was not supported if the
underlying netif wos of ppp type. Updated the code to enable setting
these interfaces up/down and registered actions in moden_netif glue for
connection/disconnection events to set the netif up/down.
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.
