bundle-uri: unit test "key=value" parsing Create a new 'test-tool bundle-uri' test helper. This helper will assist in testing logic deep in the bundle URI feature. This change introduces the 'parse-key-values' subcommand, which parses an input file as a list of lines. These are fed into bundle_uri_parse_line() to test how we construct a 'struct bundle_list' from that data. The list is then output to stdout as if the key-value pairs were a Git config file. We use an input file instead of stdin because of a future change to parse in config-file format that works better as an input file.

bundle-uri: allow relative URLs in bundle lists Bundle providers may want to distribute that data across multiple CDNs. This might require a change in the base URI, all the way to the domain name. If all bundles require an absolute URI in their 'uri' value, then every push to a CDN would require altering the table of contents to match the expected domain and exact location within it. Allow a bundle list to specify a relative URI for the bundles. This URI is based on where the client received the bundle list. For a list provided in the 'bundle-uri' protocol v2 command, the Git remote URI is the base URI. Otherwise, the bundle list was provided from an HTTP URI not using the Git protocol, and that URI is the base URI. This allows easier distribution of bundle data.

bundle-uri: parse bundle list in config format 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.
