Refactor klist insertion and removal
Rename klist_{insert,remove}() to klist_{insert,remove}_locked().
These functions assume that the caller has locked the klist. The current
state of locking remains intact because the kernel lock is still used
with all klists.
Add new functions klist_insert() and klist_remove() that lock the klist
internally. This allows some code simplification.

Simplify filterops routines where klist_invalidate() is used. klist_invalidate() detaches knotes from the list and rewires them synchronously so that the original filterops routines do not get called after the invalidation. OK anton@, mpi@

poll handlers must return a poll(2) revents value, not errno(2) values. Some drivers have returned ENXIO (6) if the device is not available which incorrectly translates into POLLPRI|POLLOUT (2|4) in userland. Change it to POLLERR for now, but it might as well be POLLHUP. OK mpi@

Fix mbuf releated crashes in switch(4). They have been found by syzkaller as pool corruption panic. It is unclear which bug caused what, but it should be better now. - Check M_PKTHDR with assertion before accessing m_pkthdr. - Do not access oh_length without m_pullup(). - After checking if there is space at the end of the mbuf, don't overwrite the data at the beginning. Append the new content. - Do not set m_len and m_pkthdr.len when it is unclear whether the ofp_error header fits at all. Use m_makespace() to adjust the mbuf.

Teach switch(4) device read(2) operations to behave like a stream socket, so the userland programs can use it without having to do any special treatment (e.g. having to read() whole packets with just 1 call or lose it). This also allows userland to read more than one ofp header/payload with one syscall. ok mikeb@
