Subject: git-svn: fix "Malformed network data" with svn:// servers
X-Git-Tag: v1.5.3.2~37

git-svn: fix "Malformed network data" with svn:// servers

We have a workaround for the reparent function not working
correctly on the SVN native protocol servers.  This workaround
opens a new connection (SVN::Ra object) to the new
URL/directory.

Since libsvn appears limited to only supporting one connection
at a time, this workaround invalidates the Git::SVN::Ra object
that is $self inside gs_fetch_loop_common().  So we need to
restart that connection once all the fetching is done for each
loop iteration to be able to run get_log() successfully.
