* PHY status API for W5500 & ENC28J60 drivers
* move linkStatus() from ArduinoEthernet:: to LwipIntfDev::
* LwipIntfDev: include PHY status into ::connected()
When using previous IDE versions, the use of an invalid category value caused a warning to be displayed on every compilation:
WARNING: Category 'Network' in library lwIP_PPP is not valid. Setting to 'Uncategorized'
WARNING: Category 'Network' in library lwIP_enc28j60 is not valid. Setting to 'Uncategorized'
WARNING: Category 'Network' in library lwIP_w5500 is not valid. Setting to 'Uncategorized'
WARNING: Category 'Network' in library lwIP_w5500 is not valid. Setting to 'Uncategorized'

* Disable WiFi at boot by default
* +define WIFI_IS_OFF_AT_BOOT
* remove now useless example
* mv enableWiFiAtBootTime() to core_esp8266_features.h
* sync with master
* per @earlephilhower review: a file was missing
* doc
* WiFi persistence is now false by default
* fix doc
* ditto
* doc: remove sphinx warnings (fix links and formatting)
* fix link name
* fix doc
* legacy: restore persistence
* undeprecate preinit()
* move force modem up to when mode has changed (per @mcspr review)
* do not wake up from sleep when mode if OFF
* fix doc per review
This commit adds W5500 W5100 and ENC28j60 drivers from @njh with credits
They are available in libraries/
An example is added in W5500 examples directory
plus:
* Extract dhcp server from lwip2 and add it to the core as a class.
It must always be present, it is linked and can be called by fw on boot.
So it cannot be stored in a library.
* ethernet: static or dhcp works
* PPPServer: example
* bring WiFi.config() to the lwIP generic interface (argument reorder common function)
* move hostname() from WiFI-STA to generic interface
* remove non readable characters from dhcp-server comments
* dhcp-server: magic_cookie is part of bootp rfc
* fixes from https://github.com/d-a-v/W5500lwIP/issues/17
* enable lwip_hook_dhcp_parse_option()
* +ethernet tcp client example in w5500 library examples
