[RESEND PATCH 03/12] golang/xenlight: fix string conversion in generated toC functions



In gengotypes.py, the toC functions only set C string fields when
the Go strings are non-empty. However, to prevent segfaults in some
cases, these fields should always at least be set to nil so that the C
memory is zeroed out.

Update gengotypes.py so that the generated code always sets these fields
to nil first, and then proceeds to check if the Go string is non-empty.
And, commit the new generated code.
