>Description:
	
	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 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.
