sched/group: On task creation, do not clone uninitialized descriptors.
...
Sockets are created in two steps:
1. The socket is allocated, then
2. The socket is initialized.
In SMP mode, there is a possibility that a pthread executing one CPU may create a new task while a pthread on another CPU has allocated the socket but not yet initialized it. This commit updates the socket clone test to assure that the socket is both allocated and initailized.
Without the change, it is possible that uninitialized sockets could be cloned, leading to errors later in the newly started task.

Squashed commit of the following:
...
psock_close() and net_close() are internal OS functions and should not set the errno variable.
psock_ioctl() and netdev_ioctl() are internal OS functions and should not set the errno variable.
net_dupsd() and net_dupsd2() are internal OS functions and should not set the errno variable.
net/ and fs/: net_vfcntl(), file_fcntl(), file_dup(), and file_dup2() are all internal OS interfaces and should not modify the errno value.

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.

TCP: check for connection before deleting it
...
It is possible for a socket to have no connection, for example if a TCP
socket is waiting in accept. This checks for this condition in case the
socket is closed from a different thread.

TCP: attempt to flush the write buffers before closing
...
When a socket is closed, it should make sure that any pending write
data is sent before the FIN is sent. It already would wait for all
sent data to be acked, however it would discard any pending write
data that had not been sent at least once.
This change adds a check for pending write data in addition to unacked
data. However, to be able to actually send any new data, the send
callback must be left. The callback should be freed later when the socket
is actually destroyed.

TCP networking: Since the network monitor now allocates a callback structure, it is critical to make sure that the networking monitor is stopped when the socket is closed or any other loss of connection. What was innocuous before would now be a memory leak

net_startmonitor.c always returned zero. In the case where a socket has already been closed, it correctly handled the disconnetion event but still returned OK. Returning OK causes the callers of net_startmonitor to assume that the connection was okay, undoing the good things that net_startmonitor did and causing the socket to be marked as connected. This behavior was noted by Pelle Windestam.

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.
