In preparation for moving sockbuf locks into the containing socket, provide alternative macros for the sockbuf I/O locks: SOCK_IO_SEND_(UN)LOCK() and SOCK_IO_RECV_(UN)LOCK(). These operate on a socket rather than a socket buffer. Note that these locks are used only to prevent concurrent readers and writters from interleaving I/O. When locking for I/O, return an error if the socket is a listening socket. Currently the check is racy since the sockbuf sx locks are destroyed during the transition to a listening socket, but that will no longer be true after some follow-up changes. Modify a few places to check for errors from sblock()/SOCK_IO_(SEND|RECV)_LOCK() where they were not before. In particular, add checks to sendfile() and sorflush().
