svn-fe produces fast-import stream for a fixed refs/heads/master ref.
It is usually desired to write to a different ref. In a remote helper
it would be a ref in private namespace. If svn-fe is used by someone
directly it'll be more safe to remind where the commits can go. And
in both cases it may be needed to import from two repos and hence to
different refs.
Add a destination ref parameter to vcs-svn/, a corresponding parameter
to svn-fe and a simple test for it.
$ svn-fe --ref=refs/heads/master ...
is an explicit way to stay with the default destination.
