vcs-svn: avoid using ls command twice
Currently there are two functions to retrieve the mode and content
at a path:
const char *repo_read_path(const uint32_t *path);
uint32_t repo_read_mode(const uint32_t *path)
Replace them with a single function with two return values. This
means we can use one round-trip to get the same information from
fast-import that previously took two.
