from its parent so that LOG_PERROR would work. However, this caused
dhclient(8)'s stdio streams to remain open across daemonization, breaking
the ability to capture its foreground output as done in netconfig_ipv4.
Fix this by reverting r341692 and instead passing the parent's stderr
descriptor as an argument to cap_openlog() only when LOG_PERROR is specified
in logopt.

Instead of passing flags (which describe a type of nvlist)
every send/recv we remember them in channel.
It's enough for use to extract them only during unwrap.
This simplify use of Casper.

syslog in libc secretly reconnects to the daemon.
Another issue is that we don't have any information from openlog(3) if we
succeeded to open log or not so we don't know if we are ready
to enter cabability mode.
Because all of that we decided we need a syslog service for Caspser.
