Ralph Boehme 593abe5f6b s3:rpc_server: allow building RPC services as shared modules
This is the general RPC subsystem change, existing modules must be
tweaked to support being loaded as a module.

The next commit shows how to do this for the Spotlight RPC service.

The general syntax is: --with-shared-modules=rpc_NAME_module
