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.

- Update FreeBSD Heimdal distribution to version 1.5.1. This also brings
several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.

We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.

- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.

- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.

- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.

- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.

- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.
