[PATCH 05/10] vcs-svn: split off function to export result from delta application

[Jonathan Nieder <jrnieder@gmail.com>]

In this time of heavy experimentation, we will need multiple
fast_export_blob_delta variants.  Make this easier by factoring
out the common part.

Also not needed, except perhaps as code cleanup.
