tcpdump: Do not hard code HAVE_LIBCRYPTO in config.h

Partially revert r323866.

Using HAVE_* is a internal tcpdump style standard.
We want to be consistent with the standard to upstream those changes in
the future.

Requested by: glebius@

We use a few different ifdef's names to check if we are using Casper or not,
let's standardize this. Now we are always use WITH_CASPER name.

Reduce diff to upstream using HAVE_CAPSICUM instead of __FreeBSD__. It'll also
make it easier to upstream HAVE_CASPER patch.

Fix spelling of the casper introduced in the r296047.

Convert casperd(8) daemon to the libcasper.
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.

Regenerate our usr.sbin/tcpdump/tcpdump/config.h for tcpdump 4.1.1, and
remove unused HAVE_RC5_H and HAVE_CAST_H defines from CFLAGS.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.
