Use P-256 for EC tests

Fedora/RedHat OpenSSL supports only P-256, P-384 and P-521.

The new mkcert.sh script can create updated certs when these
expire on Jan 17th 2038.
env KRB5CCNAME=/tmp/foocc kinit ignores the env

The problem is that fcc_get_cache_next() is called in a context where
context->default_cc_name is not set.  We should call
krb5_cc_default_name(), and that fixes the problem.  There's a comment
warning that this can result in reentering krb5_cc_cache_match(), but
nothing in libkrb5 calls krb5_cc_cache_match(), so the comment is wrong,
at least in the github tree.

An alternative would be to call krb5_cc_set_default_name(NULL) in
kuser/kinit.c before calling krb5_cc_cache_match(), however, that seems
like an insufficiently general solution.  Also, the semantics of
krb5_cc_cache_match() would differ from MIT's -- it seems better to
match MIT's semantics.
More complete logging of capths violations

It is much easier (i.e. actually possible) to debug transit path policy
violations when the logs specify the client and server realms, not just
the transit realm.
Add missing KRB-FX-CF2 test vectors (3DES broken)

Note that this shows that the our KRB-FX-CF2 is broken as to 3DES (and
the 1DES PRF is still missing).
Fix DES3 PRF

RFC 3961 says the simplified profile PRF should truncate the hash
output to "multiple of m", which MIT krb5 interprets as the largest
possible multiple of m.  RFC 6113 appendix A also uses that
interpretation for the KRB-FX-CF2 test vector.  So the DES3 PRF should
truncate the 20-byte SHA-1 result to 16 bytes, not 8.  Also make
krb5_crypto_prf_length work with DES3 by giving the DES3 enctype a
non-zero PRF length.

redhat have Linux SE rules that slows down openssh when heimdal tries

heimdal: handle referrals for 3 part DRSUAPI SPNs

This handles referrals for SPNs of the form
E3514235-4B06-11D1-AB04-00C04FC2DCD2/NTDSGUID/REALM, which are
used during DRS replication when we don't know the dnsHostName of the
target DC (which we don't know until the first replication from that
DC completes).

We use the 3rd part of the SPN directly as the realm name in the
referral.

heimdal:lib/krb5: don't name a struct 'token'

This is a static const struct and the name is never used,
so just make it an anonymous struct.

heimdal: Fix CID 240779 Allocation size mismatch

(rebased on current Heimdal by abartlet)

The error Coverity complains about is in the malloc. krb5_enctypes is
an enum, so it is usually smaller than the size of a pointer. So we
overallocate, but in the memcpy further down we copy from potentially
invalid memory.
