When a bundle provider wants to operate independently from a Git remote, they want to provide a single, consistent URI that users can use in their 'git clone --bundle-uri' commands. At this point, the Git client expects that URI to be a single bundle that can be unbundled and used to bootstrap the rest of the clone from the Git server. This single bundle cannot be re-used to assist with future incremental fetches. To allow for the incremental fetch case, teach Git to understand a bundle list that could be advertised at an independent bundle URI. Such a bundle list is likely to be inspected by human readers, even if only by the bundle provider creating the list. For this reason, we can take our expected "key=value" pairs and instead format them using Git config format. Create bundle_uri_parse_config_format() to parse a file in config format and convert that into a 'struct bundle_list' filled with its understanding of the contents. Be careful to use error_action CONFIG_ERROR_ERROR when calling git_config_from_file_with_options() because the default action for git_config_from_file() is to die() on a parsing error. The current warning isn't particularly helpful if it arises to a user, but it will be made more verbose at a higher layer later. Update 'test-tool bundle-uri' to take this config file format as input. It uses a filename instead of stdin because there is no existing way to parse a FILE pointer in the config machinery. Using git_config_from_mem() is overly complicated and more likely to introduce bugs than this simpler version.
