vcs-svn: set up channel to read fast-import cat-blob response
Set up some plumbing: teach the svndump lib to pass a file descriptor number to the fast_export lib, representing where cat-blob/ls responses can be read from, and add a get_response_line helper function to the fast_export lib to read a line from that file. Unfortunately this means that svn-fe needs file descriptor 3 to be redirected from somewhere (preferrably the cat-blob stream of a fast-import backend); otherwise it will fail: $ svndump <path> | svn-fe fatal: cannot read from file descriptor 3: Bad file descriptor For the moment, "svn-fe 3</dev/null" works as a workaround but it will not work for very long. A fast-import backend that can retrieve old commits is needed in order to be able to fulfill svn "Node-copyfrom-rev" requests that refer to revs from a previous run.
