Add secure cookie support

Remove the existing support for creating trivial cookies.  Add new
functions to fast_util.c for reading and generating secure cookies.
Add new kdcpreauth callbacks "get_cookie" and "set_cookie" to allow
preauth mechs to retrieve and set cookie values.

Based on a patch by Nathaniel McCallum.
