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
stdin 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.
