Networking: Fixes another CONFIG_NET_NOINTS issues. When called sem_timedwait() with the network locked, the network stays logcked while we wait which is not what we want (without CONFIG_NET_NOINTS, interrupts are re-enabled while we wait and all is well).

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).

Unix domain/FIFOs: Fix a race condition between FIFO buffer operations and the opening and closing of FIFOs which necessary when the FIFOs are used to support Unix domain, datagram sockets. The default policy is the deallocate FIFO buffering when the last client closes the pipe. When when used for datagram communicatinos, packets left in the FIFO will be lost. Some like UDP read-ahead is needed: The buffered data in the FIFO needs to be retained until the reader gets a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to control the buffer policy. Default (0) is the legacy behavior; Unix domain datagram logic sets the alternative policy so that the packet data persists after the FIFO is closed.

Networking: Fix a major TCP bug introduced with commit e71c09ce9777ff732cb60bd07fb43d85522f79d6. Some connection logic was reorder -- setting the socket got moved BEFORE the point where the check was made if the socket was already connected. The resulting behavior was odd: Telnet would connect, but then when you exit and reconnect, it would fail to connect. But then if try again, it would connect okay. So the symptom was connect-fail-connect-fail-...

Networking: Fix another deadlock condition. tcp_write_buffer_alloc() calls sem_wait() with network locked. That worked if CONFIG_NET_NOINTS was not defined because interrupts are automatically restored when the wait happens. But with CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad style and also can lead to a deadlock condition

Networking: The are issues with the TCP write-ahead buffering if CONFIG_NET_NOINTS is enabled: There is a possibility of deadlocks in certain timing conditions. I have not seen this with the Tiva driver that I have been users but other people claim to see the issue on other platforms. Certainly it is a logic error: The network should never wait for TCP read-ahead buffering space to be available. It should drop the packets immediately.
...
This was fixed by duplicating most of the IOB interfaces: The versions that waited are still present (like iob_alloc()), but now there are non-waiting verisons of the same interfaces (like iob_tryalloc()). The TCP read-ahead logic now uses only these non-waiting interfaces.
