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
