Here are the upgrade steps when running nnimap-split-with-parent, when
it needs to load the history-cache:

1) does the history-cache (nnmail cache version 2) file exist?  if
   yes, go to (3)

2) upgrade ~/.nnmail-cache to a new history-cache file, or create a
   new history-cache file if ~/.nnmail-cache does not exist

a) creating a new file: just touch the file 

b) upgrading: all lines get prefixed with the return value of
nnmail-cache-primary-backend, then a \t character

3) load the history-cache file with the
   "backend\tmessage-id\tgroupname" format

Does that makes sense?  From (3) on, all work is done with the new
history-cache file.  The user could even go back to using the old
nnmail-split-with-parent function in their nnmail split, since
~/.nnmail-cache would be the same as before.
