Gregory Nutt 42a0796615 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

devif

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.

ipforward

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).

net_initialize.c

Addes support for read-only routing tables. Prior to this change, routing tables were only support in RAM and had to be initialized with explicit logic to add the necessary routes to the routing table. With this change, routes may be defined in the pre-initialized, read-only routing table provided by the board-specific logic
