as to the type of the command argument: int -> u_long.
These types have different widths in the 64-bit world.
Add a note to UPDATING because the change breaks KBI

stop looking there for things like rc.d and periodic. This avoids
duplicating effort when /usr/X11R6 is a symlink to /usr/local,
which it is by default now.
It is not anticipated at this time that we will MFC this change, since
we'd like to avoid breaking legacy systems. However, there is a fix for
/etc/rc.subr in the works to avoid running any rc.d scripts twice which
we should be able to MFC.

arm and powerpc have 64KB as the maximum argument size, so one
cannot run "make delete-old" on arm or powerpc anymore. Stop
special-casing powerpc and give it 256KB of arguments like all
other platforms, but keep arm on 64KB for now. There may be a
purpose to it that doesn't exist for powerpc.
* "compression_program" support uses an external program
* Portability: no longer uses "struct stat" as a primary

out copy_stat() and stat() functions
* More complete tests for archive_entry
* Finish archive_entry_clone()
* Isolate major()/minor()/makedev() in archive_entry; remove
these from everywhere else.
* Bug fix: properly handle decompression look-ahead at end-of-data
* Bug fixes to 'ar' support
* Fix memory leak in ZIP reader
* Portability: better timegm() emulation in iso9660 reader
* New write_disk flags to suppress auto dir creation and not
overwrite newer files (for future cpio front-end)
* Simplify trailing-'/' fixup when writing tar and pax

To enable dcons in kernel, put the following lines in /boot/loader.conf.
You may also want to enable dcons in /etc/ttys.

- bounded cookie-life to 1 second minimum in socket option set.
- Delayed_ack_time becomes delayed_ack per new socket api document.
- Improve port number selection, we now use low/high bounds and
no chance of a endless loop. Only one call to random per bind
as well.
- fixes so set_peer_primary pre-screens addresses to be
valid to this host.
- maxseg did not allow setting on an assoc basis. We needed
to thus track and use an association value instead of a inp value.
- Fixed ep get of HB status to report back properly.
- use settings flag to tell if assoc level hb is on off not
the timer.. since the timer may still run if unconf address
are present.
- check for crazy ENABLE/DISABLE conditions.
- set and get of pmtud (fixed path mtu) not always taking into account ovh.
- Getting PMTU info on stcb only needs to return PMTUD_ENABLED if
any net is doing PMTU discovery.
- Panic or warning fixed to not do so when a valid ip frag is
taking place.
- sndrcvinfo appearing in both inp and stcb was full size, instead
of the non-pad version. This saves about 92 bytes from each struct
by carefully converting to use the smaller version.
- one-2-one model get(maxseg) would always get ep value, never the
tcb's value.
- The delayed ack time could be under a tick, this fixes so
it bounds it to at least 1 tick for platforms whos tick
is more than a ms.
- Fragment interleave level set to wrong default value.
- Fragment interleave could not set level 0.
- Defered stream reset was broken due to a guard check and ntohl issue.
- Found two lock order reversals and fixed.
- Tighten up address checking, if the user gives an address the sa_len
had better be set properly.
- Get asoc by assoc-id would return a locked tcb when it was asked
not to if the tcb was in the restart hash.

Add sysctl net.inet.tcp.syncache.rst_on_sock_fail defaulting to enable
that controls the behavior on socket creation failure for a otherwise
successful 3-way handshake. The socket creation can fail due to global
memory shortage, listen queue limits and file descriptor limits. The
sysctl allows to chose between two options to deal with this. One is
to send a reset to the other endpoint to notify it about the failure
(default). The other one is to ignore and treat the failure as a
transient error and have the other endpoint retransmit for another try.
