[StGit PATCH 00/10] Infrastructure rewrite series

I've expanded on the infrastructure rewrite series. As of now, clean, applied, unapplied, goto, uncommit, and the new command coalesce have been converted.

The main new development is support for index and worktree operations, so that it can do conflicting merges. This made it possible to convert "stg goto", but the main practical attraction is the vastly improved "stg coalesce", which can now take an arbitrary list of patches and reorder them so that they can be joined to one big patch. It will do so entirely automatically if the merges resolve automatically, and if they don't it will pretend to have done a series of pops, pushes, and deletes, and leave the user to manually resolve the first conflicting push.

The implementation of coalesce -- particularly the ability to fail gracefully on conflicts at any intermediate step -- is helped a lot by some new cool transaction stuff.
