replace the set_socket() method of passing an extra struct socket*
argument to ip6_output() with a new explicit struct in6pcb* argument.
(The underlying socket can be obtained via in6pcb->inp6_socket.)

remake the sets if the set files are newer than METALOG.
Useful for running DISTRIBUTION_DONE= nbmake in src/etc in order to
rebuild with new kernels and/or new ramdisk.
- If DISTRIBUTION_DONE is defined, don't add the 'root' directory to METALOG.
(maybe install -M shouldn't write to the METALOG file if it doesn't install
the file either)
- Don't re-compress the kernels if the compressed file is newer than the
kernel.
Useful if all you want to do is rebuild the ramdisk image.

Fixes a problem with signal handlers for synchronous signals noted by
Matthias Drochner on current-users.
observation is that some 570x devices can get themselves into a state
where they miscompute off-loaded TCP or UDP checksums on packets so
small that Ethernet padding is required. Further obsevation suggests
that the bge checksum-offload hardware is adding those padding bytes
into its TCP checksum computation. (Once a 5700 gets in this state,
even a warm boot won't fix it: it needs a hard powerdown.)
Work around the problem by padding such runts with zeros: even if the
checksum-offload adds in extra zeros, the resulting sum will be correct.
Also, dont trust the checksum-offload on received packets smaller than
the minimum ethernet frame, in case the Rx-side has a similar bug.
Finally, on packets where we do trust the outboard Rx-side TCP or UDP
checksum, the bge did not include the pseudo-header. Set the
M_CSUM_NO_PSEUDOHDR bit as well as M_CSUM_DATA, and rely on
udp_input() or tcp_input() adding in the sum via in_cksum_phdr().
* use ${G_HCONFIG_H} instead of hconfig.h as a dependency.
* hconfig.h: auto-build.h dependency is bogus, remove.
* misc cleanup of ".c depends on .h" -> ".o depends on .h"
* options.h was missing from CLEANFILES.
With these changes running make in this directory doesn't do a
*complete* rebuild anymore. Still not foolproof, because gen* host
tools do not overwrite generated files that are not changed, so we
really need to use stamp file style dependencies for those, like gcc
makefile does.
Ok by Matthew Green <mrg@netbsd>.
if we m_dup() a packet to compactify it, and later run out of DMA
descriptors, bge_encap() will return ENOBUFS, hoping the driver will
try again later. But we have just m_freem()'d the original chain
which was m_dup()'d, leaving a pointer to the just-freed packet header
in the tx queue.
Fix by always walking the chain, shuffling data towards the head;
except if we find a runt in the very last mbuf, we must borrow data
from its predecessor.
(Patch is verbatim from a third-party tree, apologies for any style woes.)
