hcrypto: Add exports for more crypto algorithms

Export some additional algorithms so we can make use
of them elsewhere in the code.

Allow some rfc3961 functionality to be disabled

It conflicts with v5gen in rxkad/ticket5.c

Also add include guards, which were missed previously.

libafsrpc: link afsrpc.dll to afsrfc3961.lib

Change-Id: I5bf48ed29522c0cbdc43dda63487012f14d39bbf
Update the WiX installer to know about afsrfc3961.dll
Use rfc3961 library to decrypt kerberos 5 tickets

Decrypt tickets with non-des enctypes by calling out to the rfc3961 library.
This requires the security object to be given an enhanced get_key callback
that supports looking up keys by enctype.
Include a wrapper around afsconf_GetKeyByTypes so rxkad doesn't have
to know anything about libauth internals/interfaces

Asetkey now handles afsconf_rxkad_krb5 keys too

afsconf_rxkad_krb5 keys can hold any kerberos enctype, not just des.
Allow asetkey to copy them into KeyFileExt and print them, too.

Krb5 ticket support for server-to-server and localauth

Create a tkt_MakeTicket5 that creates a native krb5 rxkad token with
a service key supported by the rfc3961 library (session keys must be
provided as DES)

Update GenericAuth to search for rxkad_krb5 keys and call tkt_MakeTicket5
if it finds any.

Derive DES/fcrypt session key from other key types

If a kerberos 5 ticket has a session key with a non-DES enctype,
use the NIST SP800-108 KDF in counter mode with HMAC_MD5 as the PRF to
construct a DES key to be used by rxkad.

To satisfy the requirements of the KDF, DES3 keys are first compressed into a
168 bit form by reversing the RFC3961 random-to-key algorithm

Windows has three additional places to get tokens, who knew?

Use the string form of key types in asetkey

Check for rxkad-k5 keys in the six-argument form and warn they are
unsupported.  Do sanity-checking on the type.

Change-Id: I571fcf88744dec271265e6a47f7d9831f867115b
Update the asetkey man page for rxkad-k5

Also add the usage for the six-argument form while here.

Update some generic text to account for the existence of rxkad-k5,
and mention that the Update Server is not the only thing which can copy
around KeyFiles.  Give an example of the seven-argument form's usage for
rxkad-k5.
Add support for deriving DES keys to klog.krb5

Merge branch 'rxkad-kdf-master' into HEAD

Merge the current OpenAFS master branch with the branch on which
OpenAFS-SA-2013-003 and OpenAFS-SA-2013-004 were developed.
