Make the link local negotiation for IPV6 in PPP optional and
configurable.
This is because some modems do not support the IPV6 negotiation and
sending IPV6CP frames would in some cases break the network
configuration phase, resulting in a timeout during the Phase Network.
Please note that this does not disable the IPV6 support for the outgoing
communication (IPV6 is still enabled even if this option is not
selected) but just for the local link between lwIP and modem.

SOMAXCONN is expected to be defined in this header, but for the esp32
port is found in net/if.h from newlib.
Avoid the issue by including the net/if.h header in sys/socket.h so that
compatibility is preserved.

Some applications (i.e. Azure IoT SDK) are expecting this header to
exist and to contain the tcp constants and description.
The esp32 did not wrap the lwip/tcp.h header, thus this commit adds a
compatibility layer.

LwIP has support for IP_PKTINFO, but it cannot be activated as it is
not configurable. This fix adds in the ability to configure it.
