net/tcp: Same change to tcp_send_buffered.c probably also applies to sixlowpan_tcpsend.c and inet_recvfrom.c

TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a situation where a NULL pointer may be dereferenced. In this configuration, the TCP connection's 'semi-permnanent' callback, s_sndcb was nullified in tcp_close_disconnect. However, other logic in tcp_lost_connection() attempt to use that callback reference after it was nullifed. Fixed in tcp_lost_connectino() by adding a NULL pointer change before the access. This was reported by Dmitriy Linikov in Bitbucket Issue 72.

Squashed commit of the following:
...
sched/semaphore: Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable. Changed all references to sem_post in the OS to nxsem_post().
sched/semaphore: Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable. Changed all references to sem_destroy() in the OS to nxsem_destroy().
libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable. Changed all references to sem_setprotocol in the OS to nxsem_setprotocol(). sem_getprotocol() was not used in the OS

Squashed commit of the following:
...
libc/semaphore: Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable. Changed all references to sem_getvalue in the OS to nxsem_getvalue().
sched/semaphore: Rename all internal private functions from sem_xyz to nxsem_xyz. The sem_ prefix is (will be) reserved only for the application semaphore interfaces.
libc/semaphore: Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable. Changed all references to sem_init in the OS to nxsem_init().
sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.
sched/semaphoate: Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.

Networking: Fix a race condition. The accept() operation is performed with the network locked. However, the network is unlocked BEFORE the connected state is set. Therefore, a context switch may occur and the socket may no longer be connected when it is marked so. Noted by Pascal Speck.

Networking: Clean up some naming that has bothered me for a long time... There are no interrupts and no interrupt handlers in the network. There are events and event handler (there used to to be interrupt logic in there years ago but that is long, long gone).

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.
