These libraries are linked to directly by applications rather than
opened at runtime via dlopen().

pkgbase: Move libcap_ to FreeBSD-runtime

A lot of binaries present in FreeBSD-runtime depend on it so move
the libs there.

Introduce channel flags in libcasper.

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.

The name of the library is exactly the same like one of name the name of the
functions.

We should not create MLINKS for that one, because it's break a build.

Introduce syslog service for 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.
