MD4 cipher requires OpenSSL3's "legacy" provider, while MD5 fetched from
the "default" one. Both ciphers are unavailable in FIPS mode, however
MD5 is tolerated for RADIUS requests on local host.
The OpenSSL3 library context was missing the "default" provider, causing
MD5 encryption to fail in FIPS mode.

libkrad allows to establish connections only to UNIX socket in FIPS
mode, because MD5 digest is not considered safe enough to be used for
network communication. However, FreeRadius requires connection on TCP or
UDP ports.
This commit allows TCP or UDP connections in FIPS mode if destination is
localhost.

change_set_password() was changed to prefer TCP. However, because
UDP_LAST falls back to UDP after one second, we can still get a replay
error due to a dropped packet, before the TCP layer has a chance to
retry.
Instead, try k5_sendto() with NO_UDP, and only fall back to UDP after
TCP fails completely without reaching a server. In sendto_kdc.c,
implement an ONLY_UDP transport strategy to allow the UDP fallback.

Global dejagnu tests in src/tests/dejagnu were not following the
enforced test suite directory naming.
Resolves: rhbz#2053133
Signed-off-by: Julien Rische <jrische@redhat.com>
Since version 1.6.3, dejagnu started to enforce a naming convention that
was already in place, but not mandatory: dejagnu test directories have
to be named "testsuite". If they don't implicit relative sub-paths
resolution (e.g. "lib", "config") is not forking.
This commit renames kadm5 library's unit tests directory to match this
requirement.
This fix won't be applied upstream because these tests were removed in
version 1.20.

CMS digest and signature algorithm for the anonymous PKINIT is changed
from SHA-1 to SHA-256. SHA-1 hasn't been considered secure anymore for
this kind of purposes for some years already.

Bypass OpenSSL's restrictions to use KRB5KDF in FIPS mode in case at
least one of AES SHA-1 HMAC encryption types are used.
Use OpenSSL 3.0 library context to access MD4 and MD5 lazily from
legacy provider if RADIUS is being used or RC4 encryption type is
enabled, without affecting global context.
Remove EVP_MD_CTX_FLAG_NON_FIPS_ALLOW flag since does not have any
effect anymore.
Such exceptions should not be allowed by the default FIPS crypto
policy.
