Peter Krempa 69615c91c8 scripts/apibuild: Extract and format API ACLs 
As an additional step before processing the API parse the protocol file
and extract all ACL definitions. This way we can distribute them for any
user of the libvirt API XML files. We will be also able to avoid another
call to gendispatch, which generates all this data into a standalone
XML.

The remote procedure to API name is inspired by what rpcgen does.
