Remove a useless kernel lock from the TCP socket splicing path. When send buffer space in the drain socket becomes available, a task is added to move data, and also the userland was informed. The latter is not usefull as this would mix a kernel and user stream. So programs do not wait for this event. Avoid calling sowakeup() from sowwakeup(), this also reduces grabing the kernel lock. Instead inform the userland about the write event when the splicing is dissolved in sounsplice(). OK claudio@

On localhost a user program may create a socket splicing loop. After writing data into this loop, it was spinning forever causing a kernel hang. Detect the loop by counting how often the same mbuf is spliced. If that happens 128 times, assume that there is a loop and abort the splicing with ELOOP. Bug found by tedu@; OK tedu@ millert@ benno@

Implement an idle timeout for the socket splicing. A new `sp_idle' field of the `splice' structure can be used to specify a period of inactivity after which splicing will be dissolved. ETIMEDOUT error retrieved with a SO_ERROR indicates the idle timeout expiration. With comments from and OK bluhm.

There existed a race when a process was trying to read from a spliced socket. soreceive() releases splsoftnet for uiomove(). In that moment, somove() could pull the mbuf from the receive buffer. After that, soreceive removed the mbuf again. The corrupted length accounting resulted in a panic. The fix is to block read calls in soreceive() until splicing has been finished. just commit deraadt@
