chao.an 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.

Author: Gregory Nutt <gnutt@nuttx.org>

    Run all .h and .c files modified in last PR through nxstyle.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    Net cleanup (#17)

    * Fix the semaphore usage issue found in tcp/udp

    1. The count semaphore need disable priority inheritance
    2. Loop again if net_lockedwait return -EINTR
    3. Call nxsem_trywait to avoid the race condition
    4. Call nxsem_post instead of sem_post

    * Put the work notifier into free list to avoid the heap fragment in the long run.  Since the allocation strategy is encapsulated internally, we can even refine the implementation later.

    * Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include:

    1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer
    2. Remove the net lock since xxx_callback_free already do the same thing
    3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all

    * Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention

    * Remove the unused _SF_[IDLE|ACCEPT|SEND|RECV|MASK] flags since there are code to set/clear these flags, but nobody check them.

Gregory Nutt a7fd58c4db Squashed commit of the following:
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

Gregory Nutt 21041af8a7 This commit modifies the Unix domain local socket design. Local sockets are built on top of pipes. The Local socket implementation maintained file descriptors to interrupt with the pipes. File descriptors have the bad property that they are valid only while running on the thread within the task that created the local socket.
As a policy, all internal OS implementations must use "detached" files which are valid in any context and do not depend on the validity of a file descriptor at any point in time.  This commit converts the usage of file descriptors to detached files throughout the local socket implementation.

Squashed commit of the following:

    net/local: Finish change to eliminate use of file descriptors.
    net/local:  A little more of the conversion.
    net/local: Beginning of chnages to eliminate use of file descriptors in the local socket implementeation. poll() will be a problem.
