lwip/netif struct has two places to store user's data
* netif->state (1 void*) but that might be occupied in special cases
* netif->client_dtat (n void*s) but that must be enabled in opts.h
This commit stores esp_netif_t* primarily in state, but if any special
netif is enabled in menuconfig (bridgeif, pppos), it uses netif->client_data.
This commit also fixes incorrect esp_netif that is attached to
IP_EVENT_GOT_IP6 event posted by pppos interfaces in:
c585618b97/components/esp_netif/lwip/esp_netif_lwip_ppp.c (L114)
Closes https://github.com/espressif/esp-idf/issues/9345
Fix dependency tree so that lwip doesn't depend on any specific network
interface component.
Network interface drivers shall depend on esp_netif.
esp_netif shall depend on lwip (but not on any specific interface
driver) -- it optionally depends on vfs and esp_eth (need ethernet
header for L2/bridge mode)
* esp-netif to optionally depend on esp-eth (only for l2tap config)
* esp_eth.h now includes the original ethernet header and the
ethernet-netif glue layer
* Updated examples and test to explicitely use esp-eth dependency if
needed
* Extended storage for staipassigned events to pass client's MAC address.
* Added client's MAC to dhcp server callback
* Posting the staipassigned events with clients IP and MAC address
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.
On startup of the common interface (ethernet, wifi), the lwip netif hostname was assigned to confg value .
Fixed to assign to esp-netif hostname if it exists
Closes https://github.com/espressif/esp-idf/issues/4737
To allow setting auth_type to PPPAUTHTYPE_NONE, add NETIF_PPP_AUTHTYPE_NONE
to esp_netif_auth_type_t.
So even PAP/CHAP are enabled in lwIP, the application still can set
auth_type to PPPAUTHTYPE_NONE.

Also added guide for creating a custom network capable I/O driver
And added notes about default wifi interfaces and implications of using
default short-hand creation functions.
