If we touch the global krb5_ccache we want to make that explicit,
so calling krb5_cc_default[_name] will result in an error during
the next patches.

While Active Directory does not support yet RFC 8009 encryption and
checksum types, it is possible to verify these checksums when running
with both MIT Kerberos and Heimdal Kerberos. This matters for FreeIPA
domain controller which uses them by default.

The two callers of this function want two very different things, the
common point was wanting to call smb_krb5_kt_seek_and_delete_old_entries()
however this is now done earlier in sdb_kt_copy() with
smb_krb5_remove_obsolete_keytab_entries() or an unlink() in
libnet_export_keytab().

The existing implementation did not differentiate between the case where
the relevant component was not present, and that where talloc_strndup()
failed. To correct this situation, put the result into an out parameter
on success and return an error on failure.

MIT Kerberos implements krb5_free_enctypes(), Heimdal is missing it and
offers krb5_xfree() instead.
This introduces a wrapper krb5_free_enctypes() around krb5_xfree() for
Heimdal.

We can't unconditionally assume (as we did in
third_party/heimdal_build/wscript_configure) that Heimdal has this type,
since we may have an older system Heimdal that lacks it. We must also
check whether krb5_pac_get_buffer() is usable with krb5_const_pac, and
declare krb5_const_pac as a non-const typedef if not.

HEIMDAL kerberos offers already tracing via a logging facility
through smb_krb5_init_context().
MIT kerberos offers to register a callback via krb5_set_trace_callback
with which tracing information can be routed to a common logging facility.
This is now integrated into smb_krb5_init_context_basic() offering
the same functionality for both kerberos fragrances.
