convert-legacy-stream is only used for incomming migration from pre Xen 4.7, and verify-stream-v2 appears to only be used by me during migration development - it is little surprise that they missed the main converstion effort in Xen 4.13. Fix it all up. Move open_file_or_fd() into a new util.py to avoid duplication, making it a more generic wrapper around open() or fdopen(). In libxc.py, drop all long() conversion. Python 2 will DTRT with int => long promotion, even on 32bit builds. In convert-legacy-stream, don't pass empty strings to write_record(). Join on the empty argl will do the right thing.
