data to be signed/sealed. We can use this to split the data from the signature portion of the resultant wrapped packet. This required merging the gsskrb5_wrap_size patch from lorikeet-heimdal, and fixes AES encrption issues on DCE/RPC (we no longer use a static 45 byte value). This fixes one of the krb5 issues in my list. Andrew Bartlett (This used to be commit e4f2afc34362953f56a026b66ae1aea81e9db104)
