<net/if.h>: Do not include <net/if_var.h> for _KERNEL

* Clean up an ancient leftover: do not include <net/if_var.h> from <net/if.h>
for kernel stuffs.

* Adjust various files to include the necessary <net/if_var.h> header.

NOTE:
I have also tested removing the inclusion of <net/if.h> from <net/if_var.h>,
therefore add <net/if.h> inclusion for those files that need it but only
included <net/if_var.h>. For some files, the header inclusion orderings are
also adjusted.

network - Fix altq_red

* altq_red was asserting that it could only be called from PF when in fact
it can also be called via ifq_enqueue().

* Add code to handle the ifq_enqueue path.

pf: Update to OpenBSD 4.2

All sorts of informations is now stored directly in
the mbuf header instead of a seperate mbuf tag. This
brings in a 100% performance increase in comparison
to OpenBSD 4.1. For DragonFly this basically means
this is the same performance as in 2.6, but we are
equal again with OpenBSD's pf data structures.

Necesary additions:

sys/net: add more interface groups related functions

if_creategroup()
if_addgroup()
if_delgroup()
if_getgroup()
if_getgroupmembers()

Imported from OpenBSD

carp: add carp_group_demote_adj()

altq: re-add check of packet tagging

fairq & red support, UDP nat'ing, reassembly fixed by Matthew Dillon

pf: Update packet filter to the version that comes with OpenBSD 4.1

The original OpenBSD 4.1 defaults to "keep state flags S/SA" for
all pass rules. In contrast to that we default to "no state". As
in earlier verions of pf in DragonFly the default keep-state
policy can still be set with the keep-policy option (e.g. "set
keep-policy keep state (pickups)").

DragonFly additions to pf have been kept: fairq support,
pickups.

Detailed Info on changes/additions:
* ALTQ: Fix altq to work with pf_mtag
Patch by Matthew Dillon
* libkern: Revert commit e104539
strchr was added to libkern.h together with strrch
* net/if.h: add interface groups
Imported from FreeBSD.
* netinet6/in6.h: add macros
IN6_IS_ADDR_MC_INTFACELOCAL
IN6_IS_SCOPE_EMBED
PV6_ADDR_SCOPE_INTFACELOCAL
* sys/libkern.h: Add strchr and strrchr as inline functions
Brought in from FreeBSD
* sys/net/if_var.h: Import interface groups
Import interface groups and event handlers from FreeBSD
* sys/net/if_var.h: add if_pf_kif, if_groups to struct ifnet
obtained from: Open/FreeBSD
* net/if_types.h: add IFT_ENC to non-IATA-assignments
obtained from Open/FreeBSD
* net/bpf.c: add bpf_mtap_hdr from OpenBSD
Con up a minimal dummy header to pacify bpf. Allocate
(only) a struct m_hdr on the stack.

Rename printf -> kprintf in sys/ and add some defines where necessary
(files which are used in userland, too).

Rename malloc->kmalloc, free->kfree, and realloc->krealloc. Pass 1

Rename functions to avoid conflicts with libc.

Import ALTQ support from KAME. This is based on the FreeBSD 4 snapshot.
This includes neither the ALTQ3 compat code nor the !DragonFly defines.
The macros have been replaced with inline functions in net/ifq_var.h.

This also renames pkthdr.pf_flags as it is intended as general flag bit.
Currently supported are ppp(4), sppp(4), tun(4) and wi(4), more drivers
are coming later.
