9ef2a48919 net/local: Support SO_SNDBUF option in getsockopt
For datagram unix sockets, the `SO_SNDBUF` value imposes an upper limit on the size of outgoing datagrams.

Note: We don't support to change the buffer size yet, so only add support to getsockopt now.

719191ac72 net/local: Return an error when write the too big packet.
Verification:
  Write a packet, the length is bigger than CONFIG_DEV_FIFO_SIZE.
  The return value should be -1, and the errno is EMSGSIZE.

Implement si_send/sendto/recvfrom with si_sendmsg/recvmsg, instead of
the other way round.

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.
