Without -n, we now only print a "network name" without the prefix length
under the following conditions:
1) the network address and mask matches a classful network prefix;
2) getnetbyaddr(3) returns a network name for this network address.
With -n, we unconditionally print the full unabbreviated CIDR network
prefix in the form "a.b.c.d/p". 0.0.0.0/0 is still printed as "default".

- Multichannel safe, endian safe, format safe
* Large part of critical pcm filters such as vchan.c, feeder_rate.c,
feeder_volume.c, feeder_fmt.c and feeder.c has been rewritten so that
using them does not cause the pcm data to be converted to 16bit little
endian.
* Macrosses for accessing pcm data safely are defined within sound.h in
the form of PCM_READ_* / PCM_WRITE_*
* Currently, most of them are probably limited for mono/stereo handling,
but the future addition of true multichannel will be much easier.
- Low latency operation
* Well, this require lot more works to do not just within sound driver,
but we're heading towards right direction. Buffer/block sizing within
channel.c is rewritten to calculate precise allocation for various
combination of sample/data/rate size. As a result, applying correct
SNDCTL_DSP_POLICY value will achive expected latency behaviour simmilar
to what commercial 4front driver do.
* Signal handling fix. ctrl+c of "cat /dev/zero > /dev/dsp" does not
result long delay.
* Eliminate sound truncation if the sound data is too small.

2) Do a comparison between "cat state*.au > /dev/dsp" and

- there should be no "perceivable" differences.

The head of the file ObsoleteFiles.inc contains instructions how to add

files to this list, when he removes a file/dir/lib from the basesystem.

Design goals:
- allows full control by the user (default interactive mode)
- possibility of scripted removal of obsolete files (batch mode)
- opt-in removal of files (explicit list of files)
- seperate removal of libs (2 delete targets)
Important design decissions:
- structured list of files to remove instead of a plain text file:
* allows to remove additional files if a NO_foo knob is specified
without the need to change the targets (no NO_foo knob is respected

calls to ntpd -g. ntpd is noticably slower than ntpdate, but is also more
accurate. This removes the nasty hackery in rc.d/ntpdate that would parse
out ntp servers from /etc/ntp.conf (ntpd knows how to read its own config
file). By default, ntpd *will* sync with its listed time servers. To
turn this off so that ntpd does not sync, ntpd_sync_on_start="NO" can be
added to /etc/rc.conf. If ntpd is not enabled (the default), then time is
not synced on startup. ntpdate's use has been depreciated by the ntpd
authors for quite some time so this change shouldn't be unexpected.

o Separate out local (ports) scripts that use rc.d, and the old style
startup/shutdown scripts and execute them separately. On startup the
rc.d style scripts are executed first and then the old-style scripts.
On shutdown, exactly the reverse happens.
o The rc.d ports scripts should now behave more like base system scripts.
Scripts ending in .sh will be sourced into the current shell, while the
rest will be executed in a subshell. Previously, all ports scripts,
regardless of the .sh suffix, were executed in a subshell.
o The parent script, /etc/rc.d/localpkg, passes its command line arguments
straight to the rc.d ports scripts. This means they should now honor
faststop and faststart commands as well. Old style scripts, should not see
any differences. They will still get either a start or stop command.
o The initial phrase shown during shutdown has been changed to use
"local packages" instead of "daemon processes" to be more inline with the
phrase used during local package startup. The phrases are also used only for
old-style ports script startup/shutdown, whereas previously they were being
used for both rc.d and old-style scripts. This should make startup/shutdown
