 ticket: 6869

 Fix a conceptual bug in r24639: the intermediate key container length
 should be the hash's output size, not its block size.  (The bug did
 not show up in testing because it is harmless in practice; MD5 has a
 larger block size than output size.)

 subject: hmac-md5 checksum doesn't work with DES keys
 target_version: 1.9
 tags: pullup

 krb5int_hmacmd5_checksum calculates an intermediate key using an HMAC.
 The container for this key should be allocated using the HMAC output
 size (which is the hash blocksize), not the original key size.  This
 bug was causing the function to fail with DES keys, which can be used
 with hmac-md5 in PAC signatures.
