d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

adb5d5afb4 * kame/sys/netinet6/nd6.c (nd6_rtrequest): changed a condition to 
decide whether to create an empty llinfo stricter so that a user

  also, sync up with RFC2460 routing header definition (no "strict" source
  routing mode any more)

4be7a2dcf3 Add a new feature-test macro, _NETBSD_SOURCE. If this is defined 
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
  can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
  various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
  !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them.  In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

10c252ba47 Changes to allow the IPv4 and IPv6 layers to align headers themseves, 
as necessary:
* Implement a new mbuf utility routine, m_copyup(), is is like
  m_pullup(), except that it always prepends and copies, rather
  than only doing so if the desired length is larger than m->m_len.
  m_copyup() also allows an offset into the destination mbuf, which
  allows space for packet headers, in the forwarding case.
* Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP.  These
  macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that
  architectures which do not have strict alignment constraints don't
  pay for the test or visit the new align-if-needed path.
* Use the new macros to check if a header needs to be aligned, or to
  assert that it already is, as appropriate.

Note: This code is still somewhat experimental.  However, the new
code path won't be visited if individual device drivers continue
to guarantee that packets are delivered to layer 3 already properly
aligned (which are rules that are already in use).
