Use fallbacks in the wrappers for Subversion support, instead of prefixes. The change only applies to the ambiguous URL schemes: file, http and https. The others - svn+ssh and svn - behave the same as previously. For http and https, the wrapping is implemented in 'svnrepo.py': Only when the attempt to create a httprepo instance fails, will the URL be considered for Subversion URL. For file, the ambiguity is treated much like the Mercurial core distinguishes bundle and directories. In this case, a directory that looks like a Subversion repository will *not* be considered for a Mercurial clone. Tthe command lines are more similar to before this refactor. The only option added to push & pull is --stupid; others are only added to clone. Any of these options specified to clone will be added to the generated '.hgrc'. Also, the -r/--rev option now works for clone & push.
