All to change krb5_get_credentials() ..

	* send_tgs.c (krb5_send_tgs()) Added check for a valid krb5_creds * arg.

	* mk_req_ext.c (krb5_mk_req_extended()) Require caller to pass in a
		valid krb5_creds * arg, and removed kdc_options krb5_flags
		and krb5_ccache from arg list.
	* send_tgs.c (krb5_send_tgs())
	* sendauth.c (krb5_sendauth())
		Fix calls to krb5_mk_req_extended()

	* gc_frm_kdc.c (krb5_get_cred_from_kdc()) Changed krb5_creds * in/out
		arg to be an in only arg and added krb5_creds ** out arg.

	* gc_via_tgt.c (krb5_get_cred_via_tgt()) Changed krb5_creds * in/out
		arg to be an in only arg and added krb5_creds ** out arg.

	* gc_2tgt.c (krb5_get_cred_via_2tgt()) Changed krb5_creds * in/out
		arg to be an in only arg and added krb5_creds ** out arg.

	* int-proto.h Updated prototypes for krb5_get_cred_via_tgt() and
		krb5_get_cred_via_2tgt().

	* get_creds.c (krb5_get_credentials()) Changed krb5_creds * in/out
		arg to be an in only arg and added krb5_creds ** out arg.
	* sendauth.c (krb5_sendauth())
		Routines that also require krb5_creds * in/out arg to be
		appropriately changed because krb5_get_credentials() changed.
	* gc_frm_kdc.c (krb5_get_cred_from_kdc())
	* get_fcreds.c (krb5_get_for_creds())
	* mk_req.c (krb5_mk_req())
		Other routines that needed adjusting because
		krb5_get_credentials() changed but didn't need an API change.

	* int-proto.h Don't prototype krb5_get_cred_via_tgt() twice. Use the
		second to prototype krb5_get_cred_via_2tgt().
