c65d8e6a23 net/socket: add MSG_DONTWAIT support 
MSG_DONTWAIT (since Linux 2.2)
  Enables nonblocking operation; if the operation would block, the
  call fails with the error EAGAIN or EWOULDBLOCK. This provides
  similar behavior to setting the O_NONBLOCK flag (via the fcntl(2)
  F_SETFL operation), but differs in that MSG_DONTWAIT is a per-call
  option, whereas O_NONBLOCK is a setting on the open file description
  (see open(2)), which will affect all threads in the calling process
  and as well as other processes that hold file descriptors referring
  to the same open file description.

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

cbdd590c82 Revert "include/nuttx/sched.h: Add storage for a previous signal mask. arch/: In all syscall implementations, block all signals before dispatching a system call; resotre signal mask when the system call returns." 
Using the sigprocmask() for this purpose has too many side-effects.

This reverts commit 344f7bc9f6.

93ed8b66d9 net/netlink: Add partial support for the NETLINK poll() operation. Still missing is some signal handling logic that actually wakes up the poll() when an asynchronous NETLLINK response is available. 
So although the poll() implemenation is still not yet usable, the commit is useful because it (1) does not harm, and (2) incidentally fixes a few other issues in the NETLONK response queuing that I noted in the process.
