containing the userland visible thinks (i.e. ioctl definitions).
Remove all (both) old ioctls, as they had a brain dead API and made keeping
binary compatibility more or less impossible.
Replace by several new ioctls. While there, remove any arbitrary limits
(resulting from the old, broken ioctls) and allow any length of names
and passwords.
we can run LCP and subsequent PPP negotiation.
- suppress too noisy printf() for about AIS event (if you remove the cable,
it will bark forever).
- sppp_dequeue() can return NULL even when sppp_isempty() is false, so check
it and do not deref NULL pointer.
- sppp_flush() on LMC interface shutdown.
- prepare to change BPF type on the fly (bpf_change_type).
change DLT type to cisco HDLC, as lmc driver is hardwired to cisco HDLC
on driver attach. XXX we may need to revisit this, as if_spppsubr may want
to alter this later.

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.
