While here, remove a bogus INET6 check.

kernel: Remove explicit dependencies on <sys/malloc.h> in headers.

All except <net/if_var.h> for now, it needs decoupling in drm first.
* Include <sys/malloc.h> in foo.c if they have kmalloc()/kfree() calls.
* Consistently check if MALLOC_DECLARE was declared before.
* <sys/mountctl.h>: include <sys/thread.h> for _KERNEL_STRUCTURES too
since the "struct journal" embeds "struct thread".
* <sys/tty.h>: Only two kernel sources makes use of M_TTYS.
* <sys/socketvar2.h>: Make it kernel only header.

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

pf: convert to use kmalloc instead of zalloc

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

Kernel part of PF

Kernel part of PF

Ported-by:
- Max Layer (original patch set, FreeBSD PF maintainer)
- Devon O'Dell, Simon 'corecode' Schubert (integration and DragonFly specific
changes)

In contrast to FreeBSD and OpenBSD, use direct flags in pkthdr instead of
m_tags. This reduces allocation and processing overhead.

Keep the IP header in Host Byte Order like the rest of the tree assumes.

Module support has a memory leak for vm_zones when unloading pf.ko.

pf: Update packetfilter to OpenBSD 4.4

* As correct pf function depends directly on pfsync now
compile if_pfsyn.c into pf.ko. pflog is already part
of pf.ko.

* Activate pfsync function by default. It's not a kernel
option anymore, but pfsync is very unlikley to work.
Anyway our ifconfig is missing all pfsync related options.
I will try to make pfsync working again after upgrading to
pf from OpenBSD 4.5 as pfsync changes completley then
and is not compatible anymore with prior versions.

* Also make the module unloading sane in if_pflog.c

Thanks to Alex Hornung and Aggelos Economopoulos for debugging.

PF: Fix Operating System Fingerprinting

Due to some wrongly imported byte-order conversions osfp was
broken.

Reported and tested by: Matthias Schmidt (matthias@dragonflybsd.org)

pf(4): Remove a ', 1' that had no effect (OpenBSD dev too tired, I guess).

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

all pass rules. In contrast to that we default to "no sta

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.
