vcs-svn: simplify repo_modify_path and repo_copy
Restrict the repo_tree API to functions that are actually needed. - decouple reading the mode and content of dirents from other operations. - remove repo_modify_path. It is only used to read the mode from dirents. - remove the ability to use repo_read_mode on a missing path. The existing code only errors out in that case, anyway.
