r8280: - added irpc_connect() for connecting to a irpc server by name
- make the dcerpc pipe in rpc_connect() a talloc child of the ejs connection variable. That means when the connection variable goes out of scope, the connection is automatically closed. That makes for a more natural interface for closing connections in a scripting language (tpot, you may wish to use mprSetPtrChild() in your smb glue code too) (This used to be commit 1c170138a8e82cb42958b88b94a1d567ffa88a92)
