Make the appendfile class inline-data index friendly The appendfile class needs a few changes to make it work with interleaved index files. It needs to support the tell() method, opening in a+ mode, and it needs to delay the checkinlinesize call until after the append file is written. Given that open(file, "a+") doesn't always seek to the end of the file, this adds seek operations to appendfile that understand whence args
