Fix wait loop and void cast ( #24 )
...
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage

sched/wdog: wd_start() is an internal OS function and should not set the errno value. Reviewed and updated every call to wd_start() to verify if return value is used and if so if the errno value is accessed.

Squashed commit of the following:
...
Change all calls to mq_send() and mq_timedsend() in the OS to calls to nxmq_send() and nxmq_timedsend(), making appropriate changes for differences in return values.
sched/mqueue: Add internal function nxmq_send() and nxmq_timedsend() that are equivalent to mq_send() and mq_timedsend() except that they do not create cancellation points and do to not modify the errno variable.

wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx. For the same reason, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide.
