systrace UI to be attached and re-attached, it also multiplexes across
systrace process so that one UI can function as central notification

support for a new kernel message that informs userland that an in-kernel
...
policy has been freed. this allows us to enforce the kernel policy size
limit for users while users are still able to execute an arbitary number
of applications; the protocol change is backwards compatible.

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.

sync up with latest openbsd systrace.
...
- avoid race conditions by having seqno in ioctl
- better uid/gid tracking
- "replace" policy to replace args
- less diffs, as many of local changes were fed back to openbsd already
due to the 1st item, it was impossible for us to provide backward-compatibility
(new kernel + old bin/systrace won't work). upgrade both.
