[StGit PATCH 00/13] Eliminate 'top' and 'bottom' files

The following series removes the 'bottom' and 'top' files for each patch, and instead uses the commit objects to keep track of the patches.

The patches are based on kha/safe 24a81d7a94cd7c9ad2fc741b0179db5b830cce78 and will conflict with the 'conflict' series in at least one place.

The first ten patches are actually only cleanups and refactoring that could go in regardless of the last ones. Some of the changes are not really necessary, but I did them while digging into the the code, and believe they are improvements. They should not change the way stg behaves in any way.

The eleventh one is just a sanity check before applying the last two that removes the top and bottom files.

The last two patches do the final cleansing. Obviously, this changes the format, and the format version should be increased and and update function be written. So it's not really ready to go in yet.

Also, there are some documentation changes not included in this.

Maybe I should have sent the first ten patches separately, but this makes it clearer why I did it.
