MFC r311769:

Fix rstat: symbol not in namelist from netstat

Sponsored by: Multiplay

MFC: 292394

Switch the IPsec related statistics to using the built in sysctl
variable set rather than reading from kernel memory.
This also makes the -z (zero) flag work correctly

MFC r287649:
Use a common subroutine to fetch and zero protocol stats instead of
duplicating roughly similar code for each protocol.

MFC r285782:
Fix counter reads on platforms where sizeof(uint64_t) != sizeof(uint64_t *).

PR: 201700

MFC r266418, r266448

Add the flowtype to the inpcb.

r260524:
Add -4/-6 shorthand for -finet/-finet6 in route(8) and netstat(8).

r260540:
Bump dates in nestat(1) and route(8) man pages.
Fix several small errors introduced by r260524.

Merge r262763, r262767, r262771, r262806 from head:
- Remove rt_metrics_lite and simply put its members into rtentry.
- Use counter(9) for rt_pksent (former rt_rmx.rmx_pksent). This
removes another cache trashing ++ from packet forwarding path.
- Create zini/fini methods for the rtentry UMA zone. Via initialize
mutex and counter in them.
- Fix reporting of rmx_pksent to routing socket.
- Fix netstat(1) to report "Use" both in kvm(3) and sysctl(3) mode.

Switch netstat -rn to use standard API for retrieving list
of routes instead of peeking inside in-kernel radix via kget.

Bulk sync of pf changes from head, in attempt to fixup broken build I
made in r263029.

Merge r257186,257215,257349,259736,261797.

These changesets split pfvar.h into several smaller headers and make
userland utilities to include only some of them.
