When a repository is transferred from one file system to another, many of the config settings that represent the properties of the file system may be wrong. This adds a new public API that will refresh the config settings of the repository to account for the change of file system. This doesn't do a full "reinitialize" and operates on a existing git_repository object refreshing the config when done. This commit then makes use of the new API in clar as each test repository is set up. This commit also has a number of other clar test fixes where we were making assumptions about the type of filesystem, either based on outdated config data or based on the OS instead of the FS.
