kerberos: Fix numerous segfaults when using weak crypto

Weak crypto is provided by the openssl legacy provider which is
not load by default. Load the legacy providers as needed.

When the legacy provider is loaded into the default context the default
provider will no longer be automatically loaded. Without the default
provider the various kerberos applicaions and functions will abort().

This is the second attempt at this patch. Instead of linking
secure/lib/libcrypto at build time we now link it at runtime, avoiding
buildworld failures under Linux and MacOS. This is because
TARGET_ENDIANNESS is undefined at pre-build time.

Revert "kerberos: Fix numerous segfaults when using weak crypto"

This revision breaks Linux and MacOS cross builds because
TARGET_ENDIANNESS is not define during bootstrapping on these
platforms.

I think the correct approach would be to separate the new
fbsd_ossl_provider_load() and unload functions into their own
library (instead of libroken). This avoids the less desirable
option of including bsd.cpu.mk in secure/lib/Makefile.common,
which does build but could complicate future work.

Update the existing heimdal implementation for OpenSSL 1.1.

Existing work is underway to import a newer version of heimdal, but
this patchset gets us to a fully working tree to enable more wide
spread testing of OpenSSL 1.1 for now.

I've also enabled WARNS=1 for kerberos (which is the reason for the
change in libroken). Having -Werror enabled was useful during the
1.1 updates and we probably should have warnings enabled by default
for kerberos anyway.

This passes make tinderbox, and I have also done some very light
runtime testing on amd64.

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.

Define OPENSSL_DES_LIBDES_COMPATIBILITY so that Heimdal will build with
OpenSSL 0.9.7 when it is imported. (This currently has no effect.)
