Junio C Hamano d475536658 Merge branch 'svn-fe' of git://repo.or.cz/git/jrn into jn/svn-fe ...

This simplifies svn-fe a great deal and fulfills a longstanding wish:
support for dumps with deltas in them, and incremental imports.

The cost is that commandline usage of the svn-fe tool becomes a little
more complicated since it no longer keeps state itself but instead reads
blobs back from fast-import in order to copy them between revisions and
apply deltas to them.

Also removes a couple of custom data structures and replaces them with
strbufs like other parts of Git.

  vcs-svn: reset first_commit_done in fast_export_init
