libc4.6.27.

I left out two changes that weren't related to that problem but
were necessary to get arlad to compile and both caused fairly obvious
compile-time problems.  The arla.c change should probably be replaced
by an implementation of krb_get_err_text and shouldn't be necessary
for a modern kerberos, but it's there for completeness.

Everything that didn't compile with these patches needed libkafs,
which I don't have yet.
