MFC r342605:

TCP_PAWS_IDLE is does not exist in NetBSD and illumos. In FreeBSD
TCP_PAWS_IDLE is defined in netinet/tcp_seq.h, however this header
isn't included explicitly or implicitly at this point therefore
as far ipfilter is concerned TCP_PAWS_IDLE is not defined. Remove
the #ifdef and include netinet/tcp.h unconditionally.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Resolve conflicts (and believe me...you don't want to know).

* Someone imported a lot of files with the wrong CVS tag, so lots of files need
that fixed in them....
* Keep unnecessary files out of the non-vendor part of this CVS repository.
