* All variables are now embraced: ${foo}
* All comparisons against some value now take the form:
[ "${foo}" ? "value" ]
where ? is a comparison operator
* All empty string tests now take the form:
[ -z "${foo}" ]
* All non-empty string tests now take the form:
[ -n "${foo}" ]

respectively logging and dropping ICMP REDIRECT packets.
Note that there is no rate limiting on the log messages, so log_redirect
should be used with caution (preferrably only for debugging purposes).

Allow a ppp startup option in rc.conf.
Adjust sysinstall so that it appends to the end of ppp.conf
and uses the generated profile to start ppp in auto mode on
boot.

get a list of interfaces, and then automatically configure them if
${ifconfig_${ifn}} or /etc/start_if.${ifn} exists.
This makes it a lot easier to deal with machines that constantly change
their network configuration as you can leave ifconfig settings for all
the possible cards - just the ones that are present will be configured.
and set it to "/etc/pccard.conf.sample" in /etc/defaults/rc.conf.
Perhaps this default value can be inappropriate,
but I set to this value for the convenience of PC-card boot.flp users.
Please correct it if there are better solutions.
Do discard standard output from the sysctl for approxy_all, and echo
what this sysctl is doing in the usual way. This fix is probably
backwards. We should probably just use the standard sysctl output
in all cases (it needs to have a newline filtered out).
Echo what the sysctls for nfs_reserved_port_only and nfs_access_cache
are doing.

Despite their name it doesn't keep TCP sessions alive, it kills
them if the other end has gone AWOL. This happens a lot with
clients which use NAT, dynamic IP assignment or which has a 2^32
* 10^-3 seconds upper bound on their uptime.
There is no detectable increase in network trafic because of this:
two minimal TCP packets every two hours for a live TCP connection.
Many servers already enable keepalives themselves.
The host requirements RFC is 10 years old, and doesn't know about
the loosing clients of todays InterNet.
log_in_vain:
log_in_vain turns on logging for packets to ports for which
there is no listener.
rc.sysctl:
A generic way to set sysctl values. It reads /etc/syslog.conf
and sets values based on that. No /etc/syslog.conf has been
checked in yet, and I've not added this to the makefile yet
until I get more feedback.

This is closely tied to Hellmuth's impending rc patches for ISDN, but
sppp can also be used separately (thus it doesn't go directly into the
planned ISDN section of rc.conf).
