OK, I shall arrange that each type libxl_FOO has a libxl_FOO_init which
cannot fail and which is (normally) generated from the IDL. Likewise I
will arrange for a libxl_FOO_setdefaults which can fail.

This gives us the freedom to have non-zero representation for the
default on a per-type or per-field exceptional basis.

This will however make this series even larger...
