[PATCH 0/5] Towards a Git to SVN bridge

Hi,

Thanks to Jonathan, Junio, Peter, and Erik among others for reviewing previous iterations of this series. This iteration should take care of most error handling and design issues addressed in the previous iterations- it also comes along with a battery of tests.

Small introduction: svn-fi's design is modelled after git-fast-import.
It aims to be more comprehensive and production-ready than the
existing alternative, git2svn.  It converts a fast-import stream
to a Subversion dumpfile which can be loaded using `svnadmin load` (or
alternatively using `svnrdump load`, which will feature in Subversion
1.7).  The shortcomings can be summarized as follows:
1. dir_cache is a very naive implementation using string_list.  This
will not scale well either in memory or time, and should be replaced
with a prefix tree in future.
2. It currently only supports one branch. For supporting multiple
branches, two things need to be implemented: a branch-specific
dir_cache, and a mapper that maps branch names to directories (if the
standard "trunk", "branches", "tags" layout is not to be hardcoded).
3. Tags are currently unsupported, although it should be trivial to
implement once a mapping is in place.
4. Merges are unsupported.  This requires more thought.
5. The `from` command in the fast-import stream is ignored.  This
should probably be implemented like branching.
6. The data can't make round trips back-and-fourth yet.  Although this
topic has been discussed at length, there is no implementation of this
yet.

Thanks for reading.
