Bug in run_events()

Guys,

The current run_events() in the samba-3.0.25 tree claims to
run all events but currently does not as it breaks out at
the first event that is not ready to run ignoring any
remaining events in the list.

I've tested the attached patch with some other changes
to winbindd_cred_ccache.c and it fixes the krb5 ticket
refresh bug I'm seeing.

Comments?

Note that resetting the iterator at the end of the
processing loop could cause us to rescan previously
future events, but this is the same behavior as we
had previously when relying on the event to remove
itself from (and possibly re-add itself to the list).





cheers, jerry
