svn rev #17579: trunk/src/lib/krb5/krb/

[tlyu@MIT.EDU]

Commit By: tlyu
Log Message: 
	* gc_frm_kdc.c: Rewrite to modularize significantly.  (~400-line
	functions do not deserve to live.)  The outer loop no longer
	explicitly attempts the direct path to the target; that attempt
	has been folded into the inner loop.  Remove some redundant
	credential lookups present in the old code.  Treat unexpected
	realm referrals as soft errors, in case some intermediate KDC
	disagrees with client regarding a transit path.
