Xiang Xiao 6a3c2aded6 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

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

* Name: nxtk_setsize
*
* Description:
* Set the size for the selected client window. This size does not
* include the sizes of the borders nor for any toolbar. Those sizes
* will be added in to set the full window size.
*
* Input Parameters:
* hfwnd - The window handle returned by nxtk_openwindow
* size - The new size of the client sub-window.
*
* Returned Value:
* OK on success; ERROR on failure with errno set appropriately
