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.

s4-heimdal: Remove the execute flag of cfx.c.

The scripts which are extracting debuginfo are looking for files with
the executable bit and find cfx.c which isn't a executable.
heimdal: Fix the build on FreeBSD

We don't have BACKTRACE_SYMBOLS by default
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.

This hopefully fixes the build on AIX:

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.
