History
andre c59c83ebb6 Replace the ill-named ZERO_COPY_SOCKET kernel option with two 
more appropriate named kernel options for the very distinct
send and receive path.

"options SOCKET_SEND_COW" enables VM page copy-on-write based
sending of data on an outbound socket.

NB: The COW based send mechanism is not safe and may result
in kernel crashes.

"options SOCKET_RECV_PFLIP" enables VM kernel/userspace page
flipping for special disposable pages attached as external
storage to mbufs.

Only the naming of the kernel options is changed and their
corresponding #ifdef sections are adjusted.  No functionality
is added or removed.

Discussed with:	alc (mechanism and limitations of send side COW)
