* [PATCH lksctp-tools 01/12] build: remove internal copy of kernel header

To: linux-sctp
The library should not use a static copy, as that creates problems on
how to conform to what the kernel expects. One example is the struct
sctp_event_subscribe, which the kernel only accepts buffers up to the size
it wants. Larger buffers, which would happen if an updated library is
built/ran under an old kernel, are rejected.
Subsequent patches will adjust the library so it can adapt itself to the
kernel-headers available at compile time.
