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.

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.

TCP connect. Move the location where the socket is marked as connected in order to avoid a potential race condition

TCP networking: In the TCP connection operation, it was trying to setup the network monitor BEFORE the socket was successfully connected. This, of course, has ALWAYS failed because the socket is not yet connected and the TCP state is not yet correct for a connected socket. However, because of other changes net_startmonitor(0 no returns a failure condition that causes worse problems when trying to connect. The fix is to move the logic that starts the network monitor to AFTER the socket has been successfully connected.

Costmetic changes to networking logic

33085cb309
Networking: The network device list was protected by a re-entrant semaphore. With the recent change to support network device callback, the network stack needs to access the network device list too. Some drivers, however, run the network stack from the interrupt level -- this is bad but a fact in the current state. Of course,those drivers are unable to take the semaphore and will assert.
...
The solution here is to eliminate the device devices semaphore altogether. This eliminates netdev_semtake() and netdev_semgive() and replaces them with net_lock() and net_unlock() which have larger scope as needed for this purpose.

Networking: setsockopt() fails when setting timeouts to values less that an 100 msec. That is because the timeout is limited to stops of 1 decisecond and because the conversion of structure timeval was truncating the microsecond remainder. The utility net_timeval2dsec now accespts and option to determin how it handles the remainder: truncate, discarding the remainder, use the remainder to round to the closed decisecond value, or use any non-zero remainder to the next larger whole decisecond value.
...
For the setsockopt() case, it will always use the final option. This means that a time of zero (i.e., not timeout) can only occur if the value zero was explicated provided to setsockopt().

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.
