Networking: A placeholder for some missing logic in the previous change related to monitoring network status for dup'ed sockets. If one of the dup'ed socket's is closed, then network monitor resources associated with that one socket must be recovered. Also, in the event that socket is being used on one thread, but then closed on another, any threads waiting for events from the socket should be informed of the closure. That latter requirement is not implemented because current data structures do not support it.

Networking: TCP disconnection callbacks are not retained in a list. This will support mutiple callbacks per lower-level TCP connection structure. That is necessary for the cae where a socket is dup'ed and shares the same lower-level connection structure. NOTE: There still needs to be a call to tcp_start_monitor() when the socket is dup'ed.

6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started.

Add user-space networking stack API (usrsock)
...
User-space networking stack API allows user-space daemon to
provide TCP/IP stack implementation for NuttX network.
Main use for this is to allow use and seamless integration of
HW-provided TCP/IP stacks to NuttX.
For example, user-space daemon can translate /dev/usrsock
API requests to HW TCP/IP API requests while rest of the
user-space can access standard socket API, with socket
descriptors that can be used with NuttX system calls.
