[PATCH 0/6] archive: refactor and cleanup

This series is a collection of cleanups for git archive that I finally need to get out, reviewed and (hopefully!) integrated. It should make adding more format backends easier.

Patch 2 adds a context parameter to read_tree_recursive(), thus affecting all its callers. The rest of the patches change *archive*.[ch], only.
