 Modify the preath plugin interface so that a plugin's context is
 global to all the modules within a plugin.  Also, change the
 client-side interface so that the preauth plugin context (once
 created) lives the lifetime of a krb5_context.  This will allow
 future changes that can set plugin parameters.  The client side
 request context lives the lifetime of a call to krb5_get_init_creds().
 
 Make the sample preauth plugins buildable outside the source tree.
 
 Fix minor memory leak in sort_krb5_padata_sequence().
 
 Add a prototype for krb5_do_preauth_tryagain() and change the plugin
 interface.
 
 Incorporates fixes from Nalin Dahyabhai <nalin@redhat.com> for leaks
 of the function table pointers (rt #4566) and fix KDC crash (rt #4567)
