This commit removes the lock from the list manipulation code in esp_netif_objects.c,
because we already have another lock/task context for lwip.
So the list manipulation is unsafe and safety must be assured by the stack layer
(in esp_netif_lwip).
Problems with current locking:
* implementation of locking was wrong -- lazy init style of creating the mutex is not
thread safe (and destroying it if we have no interface makes the problem exhibit very frequently)
* locking only the list won't solve issues when assessing interfaces atomically
* maintaining multiple locks is problematic, as we often switch between
lwip context and user context in internal implementation of esp_netif_lwip

esp_netif_set_dns_info() was available only for standard interfaces, not
for Point to point types (PPP, SLIP), but it should be normally
supported. Moreover DNS servers are global in lwip, so it doesn't really
depend on type of the interface.
Also added some minor fixes to the esp_netif_get_dns_info() to allow for
NULL parameters (as it's a public API) and hardcode the IPv4 type in
case of DHCP server capable interface.
Updated logs and added error checks to the original API, before we
launch the lwIP counterpart.
Closes https://github.com/espressif/esp-idf/issues/8648
IP update notification for "point to point" interfaces is performed
via the same callback function as for any other interfaces (dhcp_cb,
although it's not DHCP related). In P2P interfaces we have to assure
that we always get a notification, so we can set the interface up.
This was omitted when getting the same IP address for the second
time, causing the PPPoS interface (in esp-modem applications) failing
to reconnect if disconnected.

It is required to define a mandatory dependency on lwip, so we
introduced esp_netif_stack component and made it require lwip, instead
of directly depending on lwip.
This enables building w-out lwip and support other TCP/IP stacks.
