bundle: extend the format of --type to support version and compression

We had some basic undocumented support for uncompressed bundle2 support. We now
have an official extensible syntax to specify both format type and compression
(eg: bzip2-v2).

In practice, this changeset introduce the 'v1' and 'v2' identifier to make it
possible to combine format and compression. The default format is still 'v1'.
We'll care about picking 'v1' or 'v2' in regard with general delta in the next
changesets.

    If you omit the destination repository, then hg assumes the
    destination will have all the nodes you specify with --base
    parameters. To create a bundle containing all changesets, use
    -a/--all (or --base null).

    You can change compression method with the -t/--type option.
    The available compression methods are: none, bzip2, and
    gzip (by default, bundles are compressed using bzip2).

    The bundle file can then be transferred using conventional means
    and applied to another repository with the unbundle or pull
    command. This is useful when direct push and pull are not
    available or when exporting an entire repository is undesirable.

    If you omit the destination repository, then hg assumes the
    destination will have all the nodes you specify with --base
    parameters. To create a bundle containing all changesets, use
    -a/--all (or --base null).

    You can change bundle format with the -t/--type option. You can
    specify a compression, a bundle version or both using a dash
    (comp-version). The available compression methods are: none, bzip2,
    and gzip (by default, bundles are compressed using bzip2). The
    available format are: v1, v2 (default to v1).

    The bundle file can then be transferred using conventional means
    and applied to another repository with the unbundle or pull
    command. This is useful when direct push and pull are not
    available or when exporting an entire repository is undesirable.
