No functional change. Minor API change that is nicer for consumers. ABI is
identical; the routine never needed to modify the pointed to value.

operation & ~limit where limit is a bool is clearly not what was intended,
given the line prior. Correct it to use the calculated mask for validation.
The cap_sysctl tests should now be functional again.
These complement cap_sysctlbyname(3) to provide a drop-in
replacement for the corresponding libc functions.
Also revise the libcap_sysctl limit interface to provide access
to sysctls by MIB, and to avoid direct manipulation of nvlists
by the caller.

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.

CASPER_SERVICE_STDIO - Casper will not close the first three descriptors (stdin,
stdout and stderr) this can be helpful for debugging.
CASPER_SERVICE_FD - Capser will not close all other descriptors, this can
be useful for a filesystem service.
After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.
