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.

It is necessary to use the RFC3961 random_to_key operation when
creating a key from a bitstring.

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.

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.
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.
Add a version of usleep() which is capable of sleeping in one
millisecond increments instead of microseconds.

openpty() is not available on all Linux distributions. Trust autoconf's
determination for HAVE_OPENPTY instead of unconditionally using
openpty() on all Linux.
The pop3, telnet and rsh/rcp support was removed from the tree in
e55b0d0ca5. Delete the corresponding
Makefiles so autoconf doesn't try to look for them.
hx509_ca_tbs_set_signature_algorithm was added by commit
c69c4634ad. It must be exported
for use by hxtool on Windows.
