  Revert r156046. We support setting dumpdev via loader tunable again.

MFC r272770 (modified version):
  When tunneling interface is going to insert mbuf into netisr queue after stripping
  outer header, consider it as new packet and clear the protocols flags.

  This fixes problems when IPSEC traffic goes through various tunnels and router
  doesn't send ICMP/ICMPv6 errors.

The SYSCTL data pointers can come from userspace and must not be
directly accessed. Although this will work on some platforms, it can
throw an exception if the pointer is invalid and then panic the kernel.

Clarify that pthread_cleanup_push()/pop() are implemented as macros that

Rework the EXAMPLES section to be a bit clearer.
- Add an example of using etcupdate diff.
- Create a subsection on bootstrapping that is below the simple
  examples.  This should make it clearer that 'etcupdate extract' is
  a one-time operation and not part of the common workflow.  It also
  adds more suggestions on when bootstrapping is needed and additional
  steps to make future merges simpler.
