New PKINIT bits, anonymous and enterprise support

I've just added anonymous Kerberos/pkinit to the KDC and the client libraries. Still only AS-REQ, what is missing is TGS-REQ and GSS-API support.
kinit --anonymous REALM

What have been implemented is draft-ietf-krb-wg-anon-04.

At the same time support for enterprise names when using PK-INIT slipped it. This is very cool, just point a cert, and the kinit will search the cert for a windows nt-name, use that with a client referrals (enterprise name) and return you a ticket for your real principal name. The only problem is that right now windows 2008 DC doesn't return client referrals PA-DATA, so that why we use --windows in the example below, it disable the client check.
kinit --windows --pk-enterprise --canon -C FILE:w2k8.pem WINDOWS2008.DOMAIN

The implementation show that the krb5_get_init_creds and friends need to be more aware PK-INIT and certificate selection. The reason the interface look the way it does is to avoid exposing that we are using hx509 beneath the kerberos library. So far I've not come up with a good langauge to express what certificate to select.

There is a query language in hx509, but its not something that you want to expose users too. Here are some examples:
%{certificate.issuer} == "C=SE,CN=hx509 Test Root CA"
%{certificate.subject} TAILMATCH "C=SE"
%{certificate.hash.sha1} EQ "412120212A2CBFD777DE5499ECB4724345F33F16"

Heimdal will show up for the Interop event in Redmond at the end of March, part of that we will do PK-INIT testing.

One things that really should be working by the is support for EC certificate and ECDSA, right now that support it not there in hx509 or hcrypto.
