65917bb8c3 fix(esp_netif): Lock netif list with TCPIP context
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

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
