TCP: add writable check during poll
...
When a poll requesting POLLOUT happens, the poll should return
immediately if a write will not block. This change adds that, as
opposed to the old behaviour of blocking until a timer from the
Ethernet driver eventually triggers the poll to complete.
This is only implemented for buffered TCP. Unbuffered TCP should
behave as before.

net/socket and net/tcp: Fix a problem in whent there are multiple network devices. Polls were being sent to all TCP sockets before. This is not good because it means that packets may sometimes be sent out on the wrong device. That is inefficient because it will cause retransmissions and bad performance. But, worse, when one of the devices is not Ethernet, it will have a different MSS and, as a result, incorrect data transfers can cause crashes. The fix is to lock into a single device once the MSS is locked locked down.

net/: Lots of build problems introduced into multiple NIC support. Many places where conditional logic based on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK. Lots of code changed with IPv6 that was never compiled with MULTINIC enabled. Still some problem with parameter passing.

ICMPv6: Adds basic logic to support verification that we have the IPv6 address in the Neighbor Table. This feature is important because otherwise the first packet sent to a remote peer will fail (it will be replaced with a Neighbor Solicitation).

net/socket and net/tcp: When we are ready to receive data or when we have outgoing data ready to be sent, we need to the notify the appropriate device driver of this condition. The notifying socket will be configured as either PF_INET or PF_INET6 and must look up the correct driver using the correct IP domain.

net/socket, net/tcp, net/udp: Add logic to select the domain of the outputgoing packet before sending any UDP or TCP packet. This sets the bit to indicate the IPv4 or IPv6 domain and the correct offset to the output going payload data.

Networking: Replace all references to net_ipaddr_t with either in_addr_t on net_ipv6addr_t. The goal is to support both IPv4 and IPv6 simultaneously. This requires that the two types be distinct and not conditionally typedef'ed to net_ipaddr_t.

If CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send operations will call arp_send() before attempting the real send operation. arp_send() will check if the the IP address mapping is in the ARP table and, if not send ARP requests periodically until it is. This eliminates losing the first outgoing message because there is not mapping in the ARP table.
