Log Message:
support for privilege elevation.

with privilege elevation no suid or sgid binaries are necessary any
longer.  Applications can be executed completely unprivileged. Systrace
raises the privileges for a single system call depending on the
configured policy.

Idea from discussions with Perry Metzger, Dug Song and Marcus Watts.
Approved by christos and thorpej.
