Add asn1c generated code for keytab controls
Instead of manually encoding controls, use an actual asn1 compiler.
The file asn1/asn1c/ipa.asn1 will contain ipa modules. The generated code
is committed to the tree and built into a static library that is linked
to the code that uses it.
The first module implements the GetKeytabControl control.
