Add support for the "rxkad-kdf" protocol for deriving rxkad session keys
from non-DES Kerberos session keys. This allows rxkad to be used in
realms where the KDC is unwilling or unable to issue tickets with
single-DES session keys.
The KDC Option and Ticket Flag for the anonymous extension were changed
from 14 to 16 due to a conflict with S4U2Proxy in version 11 of the anonymous
draft (now RFC6112). Fix the definitions
A comparison of (len > len + 1) is permitted to be optimized out
as dead code because it can't be true. Overflowing is an exceptional
condition that results in undefined behavior. The correct conditional
is (len == SIZE_MAX) when len is size_t.

Now that test_fx checks 1DES keys, we need to call allow_weak_crypto on
the test's context.
Without this fix, "make check" was failing with the following error:
lt-test_fx: krb5_crypto_init: Encryption type des-cbc-crc not
supported
The hdb_ldap_create and hdb_ldapi_create prototypes use the "static"
keyword, but the functions themselves are not implemented as static.
Heimdal's buildsystem dynamically adds function declarations to
hdb-protos.h based on the actual function implementations. Those
declarations in hdb-protos.h are not declared as static.
Since the build system generates the declarations dynamically, just
remove them from hdb-ldap.c.
When we added the get-keys privilege we lost the ability to setup
keytabs with the kadmin ext command. The fix is to note that we got
bogus key data and randkey (as we used to).
(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.

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

It is necessary to use the RFC3961 random_to_key operation when
creating a key from a bitstring.
Signed-off-by: Nicolas Williams <nico@cryptonector.com>
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.
