kerberos: Request the OpenSSL 1.1 API

This is needed to build with OpenSSL 3.0; a future update should switch
to using native OpenSSL 3 APIs.

pkgbase: split kerberos binaries and libs

Summary:
This allows installing packages that depend on kerberos libraries
without pulling in all the binaries. It also moves libgssapi to runtime
to allow installing kerbereos libraries without adding a dependancy on
the large utilities package. It makes sense to put libgssapi in runtime
rather than kerberos-lib since this is a plugin layer which is intended
to support any GSS-API mechanisms, not just kerberos.

A good example of a package which uses kerberos libraries without
needing the kerberos utilities is sshd. This uses the kerberos GSS-API
libraries to implement its GSSAPIAuthentication option.

Convert kerberos to LIBADD and reduce overlinking of the kerberos binaries and
libraries

* Remove headers from SRCS that are not generated
(and are in /usr/src/crypto/heimdal/).

* Avoid race conditions with 'make -j<N>'.

- Add missing interdependencies to kerberos libraries. Some of the
kerberos libraries were not linked properly (missing dependencies),
which causes 3rd party applications linking to fail when --as-needed
ld flag is used. I also added the --no-undefined ld(1) flag to make
sure that there're no missing dependencies.

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.

Fix conflicts after heimdal-1.1 import and add build infrastructure. Import
all non-style changes made by heimdal to our own libgssapi.
